The piano, which was featured in Big.

Big Piano (The Walking Piano) is a musical instrument, invented in 1976 by Philadelphia, Pennsylvania kinetic artist and inventor Remo Saraceni,^[1][2][3] merging dance, music, and play. The Piano is played by the user's feet where shoes, socks, or toes can tap the keys that make the music.

The film Big brought attention; the filmmakers saw it on display at the FAO Schwarz toy store with other Saraceni's designs and inventions. In a demonstration, Tom Hanks and Robert Loggia play "Heart and Soul" and "Chopsticks" without any film tricks. After Big, museums now have their own.^{[citation needed]} The synthesizer is updated to produce realistic piano sounds electronically.

Big is a 1988 romantic comedy film directed by Penny Marshall and stars Tom Hanks as Josh Baskin, a young boy who makes a wish "to be big" to a magical wishing machine and is then aged to adulthood overnight. The film also stars Elizabeth Perkins, and Robert Loggia and was written by Gary Ross and Anne Spielberg.

Big was the latest, and most successful, of a series of age-changing comedies produced in the late 1980s; the others being: Like Father Like Son (1987), 18 Again! (1988), Vice Versa (1988), the Italian film Da grande (1987).^[2][3][4][5]

Plot[link]

After being told he is too short for a carnival ride while attempting to impress an older girl (Kimberlee M. Davis), 12-year-old Josh Baskin (David Moscow) from Cliffside Park, New Jersey goes to a wishing machine called Zoltar Speaks, and wishes that he was "big." His wish is granted, but he finds out that the machine is unplugged, and backs away. By the next morning he is shocked to discover that he has been transformed into a 30-year-old man (Tom Hanks), and when he goes back to the wishing machine he finds that the carnival has already left. Fleeing from his mother (Mercedes Ruehl), who thinks he is a strange man who has kidnapped her son, Josh then finds his best friend, Billy Kopecki (Jared Rushton), at the school they both attend; Billy is shocked at first, but Josh convinces him of his identity by singing a secret song that only the two of them know. With Billy's help, he learns that it would take a couple of months to find the Zoltar Speaks machine, so Josh rents a flophouse room in New York City and gets a data entry job at MacMillan Toy Company.

By chance, Josh meets the company's owner, Mr. MacMillan (Robert Loggia), checking out the products at FAO Schwarz, and impresses him with both his extensive knowledge of current toys and his happy-go-lucky childlike enthusiasm. In a now-famous scene, the two end up playing duets together on a foot-operated electronic keyboard, performing "Heart and Soul" and "Chopsticks". This earns Josh a promotion to a dream job: testing toys all day long and getting paid for it. With his promotion, Josh's larger salary enables him to move out of the workingman's hotel and into a spacious apartment, which he and Billy fill with toys, their own Pepsi vending machine and a pinball machine. Josh soon attracts the attention of Susan Lawrence (Elizabeth Perkins), a fellow toy executive. A romance begins to develop, much to the annoyance of Susan's competitive boyfriend, Paul Davenport (John Heard). Josh becomes increasingly entwined in his "adult" life by spending more time with Susan, mingling with her friends and moving in with her. His new ideas become valuable assets to MacMillan Toys; however, Billy begins feeling annoyed and neglected, feeling that Josh has forgotten who he really is.

MacMillan asks Josh to come up with proposals for a new line of toys. Josh is intimidated by the need to formulate the business aspects of such a proposal, and Susan insists that she will handle the business end; that Josh need only rely on his affinity for toys to come up with a good idea. Nonetheless, Josh soon begins to feel overly pressured by this new life. When he expresses doubts to Susan and attempts to explain that he is really a child, she interprets this as fear of commitment on his part, and dismisses his explanation in frustration.

Longing to return to the life of a child, Josh eventually learns from Billy that the Zoltar Speaks machine is at Sea Point Park. In the middle of presenting their proposal to MacMillan and other executives, Josh leaves. After Susan realizes something is wrong, she leaves as well and encounters Billy, who tells her where Josh went. At the park, Josh finds the machine and makes a wish to become "a kid again." He is then confronted by Susan, who, seeing the machine and the fortune it gave Josh, realizes he was telling the truth. Susan becomes despondent at realizing their relationship is over. Josh tells Susan she was the one thing about his adult life he wishes would not end, and suggests she use the machine to turn herself into a little girl. She declines, indicating that being a child once was enough, and takes Josh home. After sharing an emotional goodbye, Josh, now 13, reverts to his child form and is reunited with his family.

Inventor(s)	Bartolomeo Cristofori
Developed	Early 18th century
Playing range

The piano is a musical instrument played by means of a keyboard. It is one of the most popular instruments in the world. Widely used in classical and jazz music for solo performances, ensemble use, chamber music and accompaniment, the piano is also very popular as an aid to composing and rehearsal. Although not portable and often expensive, the piano's versatility and ubiquity have made it one of the world's most familiar musical instruments.

Pressing a key on the piano's keyboard causes a felt-covered hammer to strike steel strings. The hammers rebound, allowing the strings to continue vibrating at their resonant frequency.^[1] These vibrations are transmitted through a bridge to a sounding board that more efficiently couples the acoustic energy to the air. The sound would otherwise be no louder than that directly produced by the strings. When the key is released, a damper stops the string's vibration. See the article on Piano key frequencies for a picture of the piano keyboard and the location of middle-C. In the Hornbostel-Sachs system of instrument classification, pianos are considered chordophones.

The word piano is a shortened form of pianoforte (PF), the Italian word for the instrument (which in turn derives from the previous terms "gravicembalo col piano e forte" and fortepiano). The musical terms "piano" and "forte" mean "quiet" and "loud," and in this context refers to the variations in volume of sound the instrument produces in response to a pianist's touch on the keys: the greater a key press's velocity, the greater the force of the hammer hitting the string(s), and the louder the note produced.

History[link]

Grand piano by Louis Bas of Villeneuve-lès-Avignon, France, 1781. Earliest French grand piano known to survive; includes an inverted wrestplank and action derived from the work of Bartolomeo Cristofori (ca. 1700) with ornately decorated soundboard.

Early piano replica by the modern builder Paul McNulty, after Walter & Sohn, 1805

The piano was founded on earlier technological innovations. The first string instruments with struck strings were the hammered dulcimers.^[2] During the Middle Ages, there were several attempts at creating stringed keyboard instruments with struck strings.^[3] By the 17th century, the mechanisms of keyboard instruments such as the clavichord and the harpsichord were well known. In a clavichord the strings are struck by tangents, while in a harpsichord they are plucked by quills. Centuries of work on the mechanism of the harpsichord in particular had shown the most effective ways to construct the case, soundboard, bridge, and keyboard.

The invention of the modern piano is credited to Bartolomeo Cristofori (1655–1731) of Padua, Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany, as the Keeper of the Instruments. He was an expert harpsichord maker, and was well acquainted with the body of knowledge on stringed keyboard instruments. It is not known exactly when Cristofori first built a piano. An inventory made by his employers, the Medici family, indicates the existence of a piano by the year 1700; another document of doubtful authenticity indicates a date of 1698. The three Cristofori pianos that survive today date from the 1720s.^[4][5]

While the clavichord allowed expressive control of volume and sustain, it was too quiet for large performances. The harpsichord produced a sufficiently loud sound, but had little expressive control over each note. The piano was likely formed as an attempt to combine loudness with control, avoiding the trade-offs of available instruments.

Cristofori's great success was solving, with no prior example, the fundamental mechanical problem of piano design: the hammer must strike the string, but not remain in contact with it (as a tangent remains in contact with a clavichord string) because this would dampen the sound. Moreover, the hammer must return to its rest position without bouncing violently, and it must be possible to repeat a note rapidly. Cristofori's piano action was a model for the many different approaches to piano actions that followed. Cristofori's early instruments were made with thin strings, and were much quieter than the modern piano—but compared to the clavichord (the only previous keyboard instrument capable of dynamic nuance via the keyboard) they were much louder and had more sustain.

Cristofori's new instrument remained relatively unknown until an Italian writer, Scipione Maffei, wrote an enthusiastic article about it (1711), including a diagram of the mechanism. This article was widely distributed, and most of the next generation of piano builders started their work due to reading it. One of these builders was Gottfried Silbermann, better known as an organ builder. Silbermann's pianos were virtually direct copies of Cristofori's, with one important addition: Silbermann invented the forerunner of the modern damper pedal, which lifts all the dampers from the strings simultaneously.

Silbermann showed Johann Sebastian Bach one of his early instruments in the 1730s, but Bach did not like it at that time, claiming that the higher notes were too soft to allow a full dynamic range. Although this earned him some animosity from Silbermann, the criticism was apparently heeded. Bach did approve of a later instrument he saw in 1747, and even served as an agent in selling Silbermann's pianos.^[6]

Piano-making flourished during the late 18th century in the Viennese school, which included Johann Andreas Stein (who worked in Augsburg, Germany) and the Viennese makers Nannette Streicher (daughter of Stein) and Anton Walter. Viennese-style pianos were built with wood frames, two strings per note, and had leather-covered hammers. Some of these Viennese pianos had the opposite coloring of modern-day pianos; the natural keys were black and the accidental keys white.^[7] It was for such instruments that Wolfgang Amadeus Mozart composed his concertos and sonatas, and replicas of them are built today for use in authentic-instrument performance of his music. The pianos of Mozart's day had a softer, more ethereal tone than today's pianos or English pianos, with less sustaining power. The term fortepiano is nowadays often used to distinguish the 18th-century instrument from later pianos.

In the period lasting from about 1790 to 1860, the Mozart-era piano underwent tremendous changes that led to the modern form of the instrument. This revolution was in response to a preference by composers and pianists for a more powerful, sustained piano sound, and made possible by the ongoing Industrial Revolution with resources such as high-quality piano wire for strings, and precision casting for the production of iron frames. Over time, the tonal range of the piano was also increased from the five octaves of Mozart's day to the 7⅓ or more octaves found on modern pianos.

Broadwood square action (click for page with legend)

Early technological progress owed much to the firm of Broadwood. John Broadwood joined with another Scot, Robert Stodart, and a Dutchman, Americus Backers, to design a piano in the harpsichord case—the origin of the "grand". They achieved this in about 1777. They quickly gained a reputation for the splendour and powerful tone of their instruments, with Broadwood constructing ones that were progressively larger, louder, and more robustly constructed. They sent pianos to both Joseph Haydn and Ludwig van Beethoven, and were the first firm to build pianos with a range of more than five octaves: five octaves and a fifth during the 1790s, six octaves by 1810 (Beethoven used the extra notes in his later works), and seven octaves by 1820. The Viennese makers similarly followed these trends; however the two schools used different piano actions: Broadwoods were more robust, Viennese instruments were more sensitive.

Erard square action (click for page with legend)

By the 1820s, the center of innovation had shifted to Paris, where the Pleyel firm manufactured pianos used by Frédéric Chopin and the Érard firm manufactured those used by Franz Liszt. In 1821, Sébastien Érard invented the double escapement action, which incorporated a repetition lever (also called the balancier) that permitted a note to be repeated even if the key had not yet risen to its maximum vertical position. This facilitated rapid playing of repeated notes, and this musical device was pioneered by Liszt. When the invention became public, as revised by Henri Herz, the double escapement action gradually became standard in grand pianos, and is still incorporated into all grand pianos currently produced.

Other improvements of the mechanism included the use of felt hammer coverings instead of layered leather or cotton. Felt, which was first introduced by Henri Pape in 1826, was a more consistent material, permitting wider dynamic ranges as hammer weights and string tension increased. The sostenuto pedal (see below), invented in 1844 by Jean Louis Boisselot and improved by the Steinway firm in 1874, allowed a wider range of effects.

One of the major technical innovations that helped to create the sound of the modern piano was the use of a strong iron frame. Also called the "plate", the iron frame sits atop the soundboard, and serves as the primary bulwark against the force of string tension. The increased structural integrity of the iron frame allowed the use of thicker, tenser, and more numerous strings. In a modern grand the total string tension can exceed 20 tons. The single piece cast iron frame was patented in 1825 in Boston by Alpheus Babcock, combining the metal hitch pin plate (1821, claimed by Broadwood on behalf of Samuel Hervé) and resisting bars (Thom and Allen, 1820, but also claimed by Broadwood and Érard). Babcock later worked for the Chickering & Mackays firm who patented the first full iron frame for grand pianos in 1843. Composite forged metal frames were preferred by many European makers until the American system was fully adopted by the early 20th century.

Other important advances included changes to the way the piano was strung, such as the use of a "choir" of three strings rather than two for all but the lowest notes, and the implementation of an over-strung scale in which the strings are placed in two separate planes, each with its own bridge height. (This is also called "cross-stringing". Whereas earlier instruments' bass strings were a mere continuation of a single string plane, over-stringing placed the bass bridge behind and to the treble side of the tenor bridge area. This crossed the strings, with the bass strings in the higher plane.) This permitted a much narrower cabinet at the "nose" end of the piano, and optimized the transition from unwound tenor strings to the iron or copper-wrapped bass strings. Over-stringing was invented by Jean-Henri Pape during the 1820s, and first patented for use in grand pianos in the United States by Henry Steinway, Jr. in 1859.

Duplex scaling of an 1883 Steinway Model 'A'. From lower left to upper right: main sounding length of strings, treble bridge, duplex string length, duplex bar (nickel-plated bar parallel to bridge), hitchpins, plate strut with bearing bolt, plate hole.

Duplex scaling, patented in 1872 by Theodore Steinway, enhanced the voice of each note by using sympathetic vibration. Short lengths of non-speaking wire were bridged by the aliquot throughout much of upper range of the piano, always in locations that caused them to vibrate in conformity with their respective overtones—typically in doubled octaves and twelfths. Somewhat similar systems were developed by Julius Blüthner (Aliquot stringing, 1873), as well as Pascal-Joseph Taskin (1788), and Collard & Collard (1821). Each used more distinctly ringing, undamped vibrations to modify tone, except the Blüthner Aliquot stringing which uses an additional fourth string in the upper two treble sections. While the hitchpins of these separately suspended Aliquot strings are raised slightly above the level of the usual tri-choir strings, they are not struck by the hammers but rather are damped by attachments of the usual dampers.

Some early pianos had shapes and designs that are no longer in use. The square piano (not truly square, but rectangular) was cross strung at an extremely acute angle above the hammers, with the keyboard set along the long side. This design is attributed to Gottfried Silbermann or Christian Ernst Friderici on the continent, and Johannes Zumpe or Harman Vietor in England, and it was improved by changes first introduced by Guillaume-Lebrecht Petzold in France and Alpheus Babcock in the United States. Square pianos were built in great numbers through the 1840s in Europe and the 1890s in America, and saw the most visible change of any type of piano: the iron-framed, over-strung squares manufactured by Steinway & Sons were more than two-and-a-half times the size of Zumpe's wood-framed instruments from a century before. Their overwhelming popularity was due to inexpensive construction and price, although their tone and performance were limited by narrow soundboards, simple actions and string spacing that made proper hammer alignment difficult.

The mechanism in upright pianos is perpendicular to the keys.

The tall, vertically strung upright grand was arranged like a grand set on end, with the soundboard and bridges above the keys, and tuning pins below them. The term was later revived by many manufacturers for advertising purposes. Giraffe, pyramid and lyre pianos were arranged in a somewhat similar fashion in evocatively shaped cases.

The very tall cabinet piano was introduced about 1805 and was built through the 1840s. It had strings arranged vertically on a continuous frame with bridges extended nearly to the floor, behind the keyboard and very large sticker action. The short cottage upright or pianino with vertical stringing, made popular by Robert Wornum around 1815, was built into the 20th century. They are informally called birdcage pianos because of their prominent damper mechanism. Pianinos were distinguished from the oblique, or diagonally strung upright made popular in France by Roller & Blanchet during the late 1820s. The tiny spinet upright was manufactured from the mid-1930s until recent times. The low position of the hammers required the use of a "drop action" to preserve a reasonable keyboard height.

Modern upright and grand pianos attained their present forms by the end of the 19th century. Improvements have been made in manufacturing processes, and many individual details of the instrument continue to receive attention.

History and musical performance[link]

Thelonious Monk at Minton's Playhouse, New York City, 1947

Much of the most widely admired piano repertoire in classical music, for example, that of Haydn, Mozart, and Beethoven, was composed for a type of instrument (the fortepiano) that is rather different from the modern instruments on which this music is normally performed today. Even the music of the Romantic movement, including Liszt, Chopin, Robert Schumann, Felix Mendelssohn and Johannes Brahms, was written for pianos substantially different from modern pianos.

Starting in Beethoven's later career, the fortepiano evolved into the modern piano as we know it today. Modern pianos were in wide use by the late 19th century. They featured an octave range larger than the earlier fortepiano instrument, adding around 30 more keys to the instrument. The mechanical action structure of the upright piano was invented in London, England in 1826 by Robert Wornum, and upright models became the most popular model, also amplifying the sound.^[8] Mass production in factories made them more affordable for a larger number of people. They appeared in music halls and pubs during the 19th century, providing entertainment through a piano soloist, or in combination with a small band. Pianists began accompanying singers or dancers performing on stage, or patrons dancing on a dance floor.

During the 19th century, American musicians playing for working-class audiences in small pubs and bars, particularly African-American composers, developed new musical genres based on the modern piano. Ragtime music, popularized by composers such as Scott Joplin, reached a broader audience by 1900. The popularity of ragtime music was quickly succeeded by Jazz piano. New techniques and rhythms were invented for the piano, including ostinato for boogie woogie, and Shearing voicing. George Gershwin's Rhapsody in Blue broke new musical ground by combining American jazz piano with symphonic sounds. Comping, a technique for accompanying jazz vocalists on piano, was exemplified by Duke Ellington's technique. Honky tonk music, featuring yet another style of piano rhythm, became popular during the same era. Bebop techniques grew out of jazz, with leading composers such as Thelonious Monk and Bud Powell. In the late 20th century, Bill Evans composed pieces combining classical techniques with his jazz experimentations. Herbie Hancock was one of the first jazz pianists to find mainstream popularity working with newer urban music techniques.

Pianos have also been used in rock and roll by entertainers such as Jerry Lee Lewis, Little Richard, Elton John, and Billy Joel to name just a few.

Modernist styles of music have also appealed to composers writing for the modern grand piano, including John Cage and Philip Glass.

Physics[link]

When the key is struck, a chain reaction occurs to produce the sound. First, the key raises the wippen, which forces the jack against the hammer roller (or "knuckle"). The hammer roller then lifts the lever carrying the hammer. The key also raises the damper; and immediately after the hammer strikes the wire it falls back, allowing the wire to resonate. When the key is released the damper falls back onto the strings, stopping the wire from vibrating.^[9] The vibrating piano strings themselves are not very loud, but their vibrations are transmitted to a large soundboard that moves air and thus converts the energy to sound. The irregular shape and off-center placement of the bridge ensures that the soundboard vibrates strongly at all frequencies.^[10] (See Piano action for a diagram and detailed description of piano parts.)

There are three factors that influence the pitch of a vibrating wire.

• Length: All other factors the same, the shorter the wire, the higher the pitch.
• Mass per unit length: All other factors the same, the thinner the wire, the higher the pitch.
• Tension: All other factors the same, the tighter the wire, the higher the pitch.

A vibrating wire subdivides itself into many parts vibrating at the same time. Each part produces a pitch of its own, called a partial. A vibrating string has one fundamental and a series of partials. The most pure combination of two pitches is when one is double the frequency of the other.^[11]

For a repeating wave, the velocity, v, equals the wavelength, λ, times the frequency, f.

v = λf

On the piano string, waves reflect from both ends. The superposition of reflecting waves results in a standing wave pattern, but only for wavelengths λ = 2L, L, L/2, … = 2L/n, where L is the length of the string. Therefore the only frequencies produced on a single string are f = nv/(2L). Timbre is largely determined by the content of these harmonics. Different instruments have different harmonic content for the same pitch. A real string vibrates at harmonics that are not perfect multiples of the fundamental. This results in a little inharmonicity, which gives richness to the tone but causes significant tuning challenges throughout the compass of the instrument.^[10]

Striking the piano key with greater force increases the amplitude of the waves and therefore the volume. From pianissimo (pp) to fortissimo (ff) the hammer velocity changes by almost a factor of a hundred. The hammer contact time with the string shortens from 4 ms at pp to less than 2 ms at ff.^[10] If two wires adjusted to the same pitch are struck at the same time, the sound produced by one reinforces the other, and a louder combined sound of shorter duration is produced. If one wire vibrates out of synchronization with the other, they subtract from each other and produce a softer tone of longer duration.^[12]

Types[link]

Modern pianos have two basic configurations (with subcategories): the grand piano and the upright piano.

Grand[link]

Steinway grand piano in the White House August Förster upright piano

In grand pianos, the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings, and uses gravity as its means of return to a state of rest.

There are many sizes of grand piano. A rough generalization distinguishes the concert grand (between 2.2 and 3 metres long, about 7–10 feet) from the parlor grand or boudoir grand (1.7 to 2.2 metres long, about 6–7 feet) and the smaller baby grand (around 1.5 metres (5 feet)).

All else being equal, longer pianos with longer strings have larger, richer sound and lower inharmonicity of the strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials or harmonics) sound sharp relative to whole multiples of the fundamental frequency. This results from the piano's considerable string stiffness; as a struck string decays its harmonics vibrate, not from their termination, but from a point very slightly toward the center (or more flexible part) of the string. The higher the partial, the further sharp it runs. Pianos with shorter and thicker strings, i.e. small pianos with short string scales, have more inharmonicity. The greater the inharmonicity, the more the ear perceives it as harshness of tone.

Inharmonicity requires octaves to be "stretched", or tuned to a lower octave's corresponding sharp overtone rather than to a theoretically correct octave. If octaves are not stretched, single octaves sound in tune, but double—and notably triple—octaves are unacceptably narrow. Stretching a small piano's octaves to match its inherent inharmonicity level creates an imbalance among all the instrument's intervallic relationships, not just its octaves. In a concert grand, however, the octave "stretch" retains harmonic balance, even when aligning treble notes to a harmonic produced from three octaves below. This lets close and widespread octaves sound pure, and produces virtually beatless perfect fifths. This gives the concert grand a brilliant, singing and sustaining tone quality—one of the principal reasons that full-size grands are used in the concert hall. Smaller grands satisfy the space and cost needs of domestic use.

Upright (vertical)[link]

Upright pianos, also called vertical pianos, are more compact because the frame and strings are vertical. The hammers move horizontally, and return to their resting position via springs, which are susceptible to degradation. Upright pianos with unusually tall frames and long strings are sometimes called upright grand pianos. Some authors classify modern pianos according to their height and to modifications of the action that are necessary to accommodate the height.

• Studio pianos are around 42 to 45 inches tall. This is the shortest cabinet that can accommodate a full-sized action located above the keyboard.
• Console pianos have a compact action (shorter hammers), and are a few inches shorter than studio models.
• The top of a spinet model barely rises above the keyboard. The action is located below, operated by vertical wires that are attached to the backs of the keys.
• Anything taller than a studio piano is called an upright.

Other types[link]

Player piano from 1920

The 19th century saw the introduction of the toy piano.

In 1863, Henri Fourneaux invented the player piano, which plays itself from a piano roll. A machine perforates a performance recording into rolls of paper, and the player piano replays the performance using pneumatic devices. Modern equivalents of the player piano include the Bösendorfer CEUS and the Yamaha disklavier, using solenoids and MIDI rather than pneumatics and rolls.

A silent piano is an acoustic piano having an option to silence the strings by means of an interposing hammer bar. They are designed for private silent practice.

Edward Ryley invented the transposing piano in 1801. It has a lever under the keyboard as to move the keyboard relative to the strings so a pianist can play in a familiar key while the music sounds in a different key.

The prepared piano, present in some contemporary art music, is a piano with objects placed inside it to alter its sound, or has had its mechanism changed in some other way. The scores for music for prepared piano specify the modifications, for example instructing the pianist to insert pieces of rubber, paper, metal screws, or washers in between the strings. These either mute the strings or alter their timbre. A harpsichord-like sound can be produced by placing or dangling small metal buttons in front of the hammer.

In 1954 a German company exhibited a wire-less piano at the Spring Fair in Frankfurt, Germany that sold for $238 dollars. The wires were replaced by metal bars of different alloys that replicated the standard wires when played.^[13]

Electric pianos use electromagnetic pickups to amplify the sound of the strings. Playing a note loudly causes the electric signal to clip, and the player can incorporate the distortion into his or her expressive range.

Digital pianos use digital sampling technology to reproduce the sound of each piano note. Digital pianos can be sophisticated, with features including working pedals, weighted keys, multiple voices, and MIDI interfaces. However, when one depresses the damper pedal (see below) on such an instrument, there are no strings to vibrate sympathetically. The synthesis software of some higher end digital pianos, such as the Yamaha Clavinova series, or the Kawai MP8 series, incorporates physical models of sympathetic vibration.

With the advent of powerful desktop computers, highly realistic pianos have become available as affordable software modules. Some of these modules, such as the 2004 Synthogy's Ivory, use multi-gigabyte piano sample sets with as many as 90 recordings, each lasting many seconds, for each of the 88 (some have 81) keys under different conditions. Additional samples emulate sympathetic resonance, key release, the drop of the dampers, and simulations of piano techniques like re-pedaling to augment these conditions. Some other software modules, such as Modartt's 2006 Pianoteq, use no samples whatsoever and are a pure synthesis of all aspects of the physicalities that go into the creation of a real piano's sound.

Today, piano manufactures take advantage of innovative pianos that play themselves via a CD or MP3 player. Similar in concept to a player piano, the PianoDisc or iQ systems allow pianos to "play themselves" when the software interprets a certain file format. Such additions are quite expensive, often doubling the cost of a piano. These pianos are available in both upright and grand.

Keyboard[link]

Keyboard of a grand piano

Almost every modern piano has 52 white keys and 36 black keys for a total of 88 keys (seven octaves plus a minor third, from A₀ to C₈). Many older pianos only have 85 keys (seven octaves from A₀ to A₇). The highest-quality piano manufacturers extend the range further in one or both directions.

Some Bösendorfer pianos, for example, extend the normal range down to F₀, with one other model going as far as a bottom C₀, making a full eight octave range. These extra keys are sometimes hidden under a small hinged lid that can cover the keys to prevent visual disorientation for pianists unfamiliar with the extra keys. On others, the colors of the extra white keys are reversed (black instead of white).

The extra keys are added primarily for increased resonance from the associated strings; that is, they vibrate sympathetically with other strings whenever the damper pedal is depressed and thus give a fuller tone. Only a very small number of works composed for piano actually use these notes. More recently, the Stuart and Sons company has also manufactured extended-range pianos, with the first 102 key piano. On their instruments, the frequency range extends from C₀ to F₈, which is the widest practical range for the acoustic piano. The extra keys are the same as the other keys in appearance.

Small studio upright acoustical pianos with only 65 keys have been manufactured for use by roving pianists. Known as gig pianos and still containing a cast iron harp (frame), these are comparatively lightweight and can be easily transported to and from engagements by only two people. As their harp is longer than that of a spinet or console piano, they have a stronger bass sound that to some pianists is well worth the trade-off in range that a reduced key-set offers.

The toy piano manufacturer Schoenhut started manufacturing both grands and uprights with only 44 or 49 keys, and shorter distance between the keyboard and the pedals. These pianos are true pianos with action and strings. The pianos were introduced to their product line in response to numerous requests in favor of it.

Pianos have been built with alternative keyboard systems, e.g., the Jankó keyboard.

Pedals[link]

Standard pedals[link]

Piano pedals from left to right: una corda, sostenuto and sustain pedal

Pianos have had pedals, or some close equivalent, since the earliest days. (In the 18th century, some pianos used levers pressed upward by the player's knee instead of pedals.) Most grand pianos in the US have three pedals: the soft pedal (una corda), sostenuto, and sustain pedal (from left to right, respectively), while in Europe, the standard is two pedals: the soft pedal and the sustain pedal. Most modern upright pianos also have three pedals: soft pedal, practice pedal and sustain pedal, though older or cheaper models may lack the practice pedal. In Europe the standard for upright pianos is two pedals: the soft and the sustain pedals.

Notations used for the sustain pedal in sheet music

The sustain pedal (or, damper pedal) is often simply called "the pedal", since it is the most frequently used. It is placed as the rightmost pedal in the group. It lifts the dampers from all keys, sustaining all played notes. In addition, it alters the overall tone by allowing all strings, including those not directly played, to reverberate.

The soft pedal or una corda pedal is placed leftmost in the row of pedals. In grand pianos it shifts the entire action/keyboard assembly to the right (a very few instruments have shifted left) so that the hammers hit two of the three strings for each note. In the earliest pianos whose unisons were bichords rather than trichords, the action shifted so that hammers hit a single string, hence the name una corda, or 'one string'. The effect is to soften the note as well as change the tone. In uprights this action is not possible; instead the pedal moves the hammers closer to the strings, allowing the hammers to strike with less kinetic energy. This produces a slightly softer sound, but no change in timbre.

On grand pianos, the middle pedal is a sostenuto pedal. This pedal keeps raised any damper already raised at the moment the pedal is depressed. This makes it possible to sustain selected notes (by depressing the sostenuto pedal before those notes are released) while the player's hands are free to play additional notes (which aren't sustained). This can be useful for musical passages with pedal points and other otherwise tricky or impossible situations.

On many upright pianos, the middle pedal is called the "practice" or celeste pedal. This drops a piece of felt between the hammers and strings, greatly muting the sounds. This pedal can be shifted while depressed, into a "locking" position.

There are also non-standard variants. On some pianos (grands and verticals), the middle pedal can be a bass sustain pedal: that is, when it is depressed, the dampers lift off the strings only in the bass section. Players use this pedal to sustain a single bass note or chord over many measures, while playing the melody in the treble section. On the Stuart and Sons piano as well as the largest Fazioli piano, there is a fourth pedal to the left of the principal three. This fourth pedal works in the same way as the soft pedal of an upright piano, moving the hammers closer to the strings.^[14]

Unusual pedals[link]

An upright pedal piano by Challen

The rare transposing piano (such as owned by Irving Berlin) has a middle pedal that functions as a clutch that disengages the keyboard from the mechanism, enabling the keyboard to be moved to the left or right with a lever. The entire action of the piano is thus shifted to allow the pianist to play music written in one key so that it sounds in a different key.

There were three piano companies to include extra pedals other than the standard two or three. Two of these companies offered a piano with four pedals (Crown and Schubert Piano Co.), and Wing and Son of New York offered a five-pedal piano from approximately 1893 through the 1920s. There is no mention of the company past the 1930s. Labeled left to right the pedals are Mandolin, Orchestra, Expression, Soft, and Forte (Sustain). The Mandolin pedal produces a sound similar to a vibrato feel by bouncing a set of small hammers against the strings, enabling the piano to mimic a mandolin, guitar, banjo, zither and harp. The Orchestra (Orch) pedal used a similar approach, lowering a set of metal-tipped felt strips in between the hammers and the strings. This extended the life of the hammers when the Orch pedal was used, a good idea for practicing, and created an echo-like sound that mimicked playing in an orchestral hall.^[15][16]

The pedalier piano, or pedal piano, is a rare type of piano that includes a pedalboard, enabling bass register notes to be played with the feet, as is standard on the organ. There are two types of pedal piano: the pedal board may be an integral part of the instrument, using the same strings and mechanism as the manual keyboard, or, less frequently, it may consist of two independent pianos (each with its separate mechanics and strings), which are placed one above the other, a regular piano played by the hands and a bass-register piano played by the feet. This was developed primarily as a practice instrument for organists, although there is a small repertoire written specifically for the instrument.

Construction[link]

Many parts of a piano are made of materials selected for strength and longevity. This is especially true of the outer rim. It is most commonly made of hardwood, typically maple or beech, and its massiveness serves as an essentially immobile object from which the flexible soundboard can best vibrate. According to Harold A. Conklin,^[17] the purpose of a sturdy rim is so that "the vibrational energy will stay as much as possible in the soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound."

Yet Bösendorfer, the Austrian manufacturer of high quality pianos, constructs their rim from spruce, the very same wood that the soundboard is made from. Their idea is to concertedly involve the cabinet in the projection and coloration of sound. The loss of energy into the Bösendorfer case alters the instrument's tone, giving it perhaps less power but a complex and unusually resonant sound.

View from below of a 182-cm grand piano. In order of distance from viewer: softwood braces, tapered soundboard ribs, soundboard. The metal rod at lower right is a humidity control device.

The finest hardwood rims are made by laminating thin (hence flexible) strips of hardwood, bending them to the desired shape immediately after the application of glue. This system was developed by Theodore Steinway in 1880. The thick wooden posts on the underside (grands) or back (uprights) of the piano stabilize the rim structure, and are made of softwood for stability. The requirement of structural strength, fulfilled by stout hardwood and thick metal, makes a piano heavy; even a small upright can weigh 136 kg (300 lb), and the Steinway concert grand (Model D) weighs 480 kg (990 lb). The largest piano built, the Fazioli F308, weighs 691 kg (1520 lb).

The pinblock, which holds the tuning pins in place, is another area where toughness is important. It is made of hardwood, (typically hard maple or beech), and is laminated for strength, stability and longevity. Piano strings (also called piano wire), which must endure years of extreme tension and hard blows, are made of high carbon steel. They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. The bass strings of a piano are made of a steel core wrapped with copper wire, to increase their mass whilst retaining flexibility. If all strings throughout the piano's compass were individual (monochord), the massive bass strings would overpower the upper ranges. Makers compensate for this with the use of double (bichord) strings in the tenor and triple (trichord) strings throughout the treble.

Cast iron plate of a grand piano

The plate (harp), or metal frame, of a piano is usually made of cast iron. It is advantageous for the plate to be very massive. Since the strings vibrate from the plate at both ends, vibrations absorbed by the plate result in energy loss to the desired (efficient) sound transmission channel, namely the bridge and the soundboard. While some manufacturers use cast steel in their plates, most prefer cast iron. Cast iron is easy to cast and machine, has flexibility sufficient for piano use, is much more resistant to deformation than steel, and is especially tolerant of compression. Plate casting is an art, since dimensions are crucial and the iron shrinks about one percent during cooling.

Including an extremely large piece of metal in a piano is potentially an aesthetic handicap. Piano makers overcome this by polishing, painting, and decorating the plate. Plates often include the manufacturer's ornamental medallion. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during the 1940s. Aluminum piano plates were not widely accepted, and were discontinued.

The numerous grand parts and upright parts of a piano action are generally hardwood, e.g., maple, beech, or hornbeam. However, since WWII, makers have used some plastics. Early plastics were incorporated into some pianos in the late 1940s and 1950s, but proved disastrous because they lost strength after a few decades of use. Starting in 1961, the New York branch of the Steinway firm incorporated Teflon, a synthetic material developed by DuPont, for some parts of its Permafree grand action in place of cloth bushings, but abandoned the experiment in 1982 due to excessive friction and a "clicking" that developed over time. Teflon is "humidity stable" whereas the wood adjacent to the Teflon swells and shrinks with humidity changes, causing problems. More recently, the Kawai firm built pianos with action parts made of more modern materials such as carbon fiber reinforced plastic, and the piano parts manufacturer Wessell, Nickel and Gross has launched a new line of carefully engineered composite parts. Thus far these parts have performed reasonably, but it will take decades to know if they equal the longevity of wood.

Strings of a grand piano

In all but the poorest pianos the soundboard is made of solid spruce (that is, spruce boards glued together along the side grain). Spruce's high ratio of strength to weight minimizes acoustic impedance while offering strength sufficient to withstand the downward force of the strings. The best piano makers use quarter-sawn, defect-free spruce of close annular grain, carefully seasoning it over a long period before fabricating the soundboards. This is the identical material that is used in quality acoustic guitar soundboards. Cheap pianos often have plywood soundboards.

In the early years of piano construction, keys were commonly made from sugar pine. Today they are likely to be made of spruce or basswood. Spruce is typically used in high-quality pianos. The black keys were traditionally made from ebony and the white keys were covered with strips of ivory, but since ivory-yielding species are now endangered and protected by treaty, plastics are now almost exclusively used. Also, ivory tends to chip more easily than plastic. Legal ivory can still be obtained in limited quantities. The Yamaha firm invented a plastic called "Ivorite" that they claim mimics the look and feel of ivory; it has since been imitated by other makers.

Care and maintenance[link]

The piano at the social center in the 19th century (Moritz von Schwind, 1868). The man at the piano is Franz Schubert.

Pianos need regular tuning to keep them on pitch, which is usually the internationally recognized standard concert pitch of A4 = 440 Hz. The hammers of pianos are voiced to compensate for gradual hardening, and other parts also need periodic regulation. Aged and worn pianos can be rebuilt or reconditioned. Often, by replacing a great number of their parts, they can perform as well as new pianos. Older pianos are often more settled and produce a warmer tone.^{[citation needed]}

Piano moving should be done by trained piano movers using adequate manpower and the correct equipment for any particular piano's size and weight.^{[citation needed]} Pianos are heavy yet delicate instruments. Over the years, professional piano movers have developed special techniques for transporting both grands and uprights, which prevent damage to the case and to the piano's mechanics.

Tuning[link]

A piano tuner

The relationship between two pitches, called an interval, is the ratio of their absolute frequencies. Two different intervals are perceived as the same when the pairs of pitches involved share the same frequency ratio. The easiest intervals to identify, and the easiest intervals to tune, are those that are just, meaning they have a simple whole-number ratio. The term temperament refers to a tuning system that tempers the just intervals (usually the perfect fifth, which has the ratio 3:2) to satisfy another mathematical property; in equal temperament, a fifth is tempered by narrowing it slightly, achieved by flattening its upper pitch slightly, or raising its lower pitch slightly. A temperament system is also known as a set of bearings.

Tempering an interval causes it to beat, which is a fluctuation in perceived sound intensity due to interference between close (but unequal) pitches. The rate of beating is equal to the frequency differences of any harmonics that are present for both pitches and that coincide or nearly coincide.

Piano tuning is the act of adjusting the tensions of the piano's strings, thereby aligning the intervals among their tones so that the instrument is in tune. The meaning of the term in tune in the context of piano tuning is not simply a particular fixed set of pitches. Fine piano tuning carefully assesses the interaction among all notes of the chromatic scale, different for every piano, and thus requires slightly different pitches from any theoretical standard. Pianos are usually tuned to a modified version of the system called equal temperament (see Piano key frequencies for the theoretical piano tuning). In all systems of tuning, each pitch is derived from its relationship to a chosen fixed pitch, usually A440.^[18]

Role[link]

The piano is a crucial instrument in Western classical music, jazz, film, television, and most other complex western musical genres. A large number of composers are proficient pianists—and because the piano keyboard offers an easy means of complex melodic and harmonic interplay—the piano is often used as a tool for composition.

The Marx Brothers
The four Marx Brothers in 1931. Top to bottom: Chico, Harpo, Groucho and Zeppo

The Marx Brothers were an American family comedy act, originally from New York City, that enjoyed success in Vaudeville, Broadway, and motion pictures from the early 1900s to around 1950. Five of the Marx Brothers’ thirteen feature films were selected by the American Film Institute as among the top 100 comedy films, with two of them (Duck Soup and A Night at the Opera) in the top twelve.

The core of the act was the three elder brothers, Chico, Harpo and Groucho; each developed a highly distinctive stage persona. The two younger brothers, Gummo and Zeppo, did not develop their stage characters to the same extent, and eventually left the act to pursue other careers. Gummo was not in any of the movies; Zeppo appeared in the first five.

Early life[link]

Born in New York City, the Marx Brothers were the sons of Jewish immigrants from Germany and France. Their mother, Minnie Schönberg, was from Dornum in East Frisia; and their father, Simon Marx (whose name was changed to Samuel Marx, and who was nicknamed "Frenchy") was a native of Alsace and worked as a tailor.^[1][2][3] The family lived in the then-poor Yorkville section of New York City's Upper East Side, between the Irish, German and Italian quarters.

Brothers[link]

The brothers were:

A sixth brother, Manfred ("Mannie"), was actually the first child of Samuel and Minnie, born in 1886,^[10][11][12] though an online family tree states that he was born in 1885: "Family lore told privately of the firstborn son, Manny, born in 1886 but surviving for only three months, and carried off by tuberculosis. Even some members of the Marx family wondered if he was pure myth. But Manfred can be verified. A death certificate of the Borough of Manhattan reveals that he died, aged seven months, on 17 July 1886, of 'entero-colitis,' with 'asthenia' contributing, i.e. probably a victim of influenza. He is buried at New York's Washington Cemetery, beside his grandmother, Fanny Sophie Schönberg (née Salomons), who died on 10 April 1901."^[13] A cousin of the Marx brothers was Mary Livingstone (b. Sadye Marks 1905-1983), who married comedian Jack Benny.

Stage beginnings[link]

1911 newspaper advertisement for a Marx Brothers appearance (l. to r.: Chico, Groucho, Harpo).

The brothers were from a family of artists, and their musical talent was encouraged from an early age. Harpo was amazingly talented, learning to play an estimated six different instruments throughout his career. He became a dedicated harpist, which gave him his nickname.^[14] Chico was an excellent pianist, Groucho a guitarist and singer, and Zeppo a vocalist. They got their start in vaudeville, where their uncle Albert Schönberg performed as Al Shean of Gallagher and Shean. Groucho's debut was in 1905, mainly as a singer. By 1907, he and Gummo were singing together as "The Three Nightingales" with Mabel O'Donnell. The next year, Harpo became the fourth Nightingale and by 1910, the group was expanded to include their mother Minnie and their Aunt Hannah. The troupe was renamed "The Six Mascots".

Comedy[link]

One evening in 1912, a performance at the Opera House in Nacogdoches, Texas, was interrupted by shouts from outside about a runaway mule. The audience hurried out to see what was happening. When they returned, Groucho, angered by the interruption, made snide comments about them, including "Nacogdoches is full of roaches" and "The jackass is the flower of Tex-ass". Instead of becoming angry, the audience laughed. The family then realized they had potential as a comic troupe.^[15] However, in his autobiography, Harpo Speaks, Harpo Marx states that the runaway mule incident occurred in Ada, Oklahoma.^[16] A 1930 article in the San Antonio Express newspaper states that the incident took place in Marshall, Texas.^[17]

The act slowly evolved from singing with comedy to comedy with music. Their sketch "Fun in Hi Skule" featured Groucho as a German-accented teacher presiding over a classroom that included students Harpo, Gummo and Chico. The last version of the school act, titled Home Again, was written by their uncle, Al Shean, of the famous vaudeville act Gallagher and Shean. When the Home Again tour reached Flint, Michigan, 14-year-old Zeppo joined his four brothers on stage to make it five Marx Brothers, in what is believed to be the only time, in 1915.^[18] Then Gummo left to serve in World War I, reasoning that "anything is better than being an actor!"^[19] Zeppo replaced him in their final vaudeville years and in the jump to Broadway, and then to Paramount films.

During World War I, anti-German sentiments were common, and the family tried to conceal their German origin. After learning that farmers were excluded from the draft rolls, mother Minnie purchased a 27-acre (110,000 m²) poultry farm near Countryside, Illinois, but the brothers soon found that chicken ranching was not in their blood.^[20] During this time, Groucho discontinued his "German" stage personality.

By this time, "The Four Marx Brothers" had begun to incorporate their unique style of comedy into their act and to develop their characters. Both Groucho and Harpo's memoirs say their now famous on-stage personae were created by Al Shean. Groucho began to wear his trademark greasepaint moustache and to use a stooped walk. Harpo stopped speaking onstage and began to wear a red fright wig and carry a taxi-cab horn. Chico spoke with a fake Italian accent, developed off-stage to deal with neighborhood toughs, while Zeppo adopted the role of the romantic (and "peerlessly cheesy", according to James Agee)^[21] straight man.

The on-stage personalities of Groucho, Chico and Harpo were said to have been based on their actual traits. Zeppo, on the other hand, was considered the funniest brother offstage, despite his straight stage roles. As the youngest, and having grown up watching his brothers, he could fill in for and imitate any of the others when illness kept them from performing. "He was so good as Captain Spaulding [in Animal Crackers] that I would have let him play the part indefinitely, if they had allowed me to smoke in the audience", Groucho recalled. (Zeppo did impersonate Groucho in the film version of Animal Crackers. Groucho was unavailable to film the scene in which the Beaugard painting is stolen, so the script was contrived to include a power failure which allowed Zeppo to play the Spaulding part in near-darkness.)^[22]

By the 1920s, the Marx Brothers had become one of America's favorite theatrical acts. With their sharp and bizarre sense of humor, they satirized high society and human hypocrisy. They also became famous for their improvisational comedy in free-form scenarios. A famous early instance was when Harpo arranged to chase a fleeing chorus girl across the stage during the middle of a Groucho monologue to see if Groucho would be thrown off. However, to the audience's delight, Groucho merely reacted by commenting, "First time I ever saw a taxi hail a passenger". When Harpo chased the girl back the other direction, Groucho, calmly checking his watch, ad-libbed, "The 9:20's right on time. You can set your watch by the Lehigh Valley."

Under Chico's management, and with Groucho's creative direction, the brothers' vaudeville act had led to them becoming stars on Broadway, first with a musical revue, I'll Say She Is (1924–1925) and then with two musical comedies, The Cocoanuts (1925–1926) and Animal Crackers (1928–1929). Playwright George S. Kaufman worked on the last two and helped sharpen the Brothers' characterizations.

Out of their distinctive costumes the brothers looked alike, even down to their receding hairlines. Zeppo could pass for a younger Groucho, and played the role of his son in Horse Feathers. A scene in Duck Soup finds Groucho, Harpo and Chico all appearing in the famous greasepaint eyebrows, mustache and round glasses, while wearing nightcaps. The three are indistinguishable, enabling them to carry off the "mirror scene" perfectly.

Origin of the stage names[link]

The stage names for four of the five brothers were coined by monologist Art Fisher^[21] during a poker game in Galesburg, Illinois, based both on the brothers' personalities and Gus Mager's Sherlocko the Monk, a popular comic strip of the day which included a supporting character named "Groucho the Monk". The reasons behind Chico's and Harpo's stage names are undisputed, and Gummo's is fairly well established. Groucho's and Zeppo's are far less clear. Arthur was named Harpo because he played the harp, and Leonard became Chico (pronounced "Chick-o") because he was, in the slang of the period, a "chicken chaser". ("Chickens"—later "chicks"—was period slang for women. "In England now," said Groucho, "they were called 'birds'.")^[23]

In his autobiography, Harpo explains that Milton became Gummo because he crept about the theater like a gumshoe detective.^[24] Other sources report that Gummo was the family's hypochondriac, having been the sickliest of the brothers in childhood, and therefore wore rubber overshoes, also called gumshoes, in all kinds of weather. Groucho stated that the source of the name was Gummo wearing galoshes. Either way, the name relates to rubber-soled shoes.

The reason Julius was named Groucho is perhaps the most disputed. There are three explanations:

• Julius' temperament: Maxine, Chico's daughter and Groucho's niece, said in the documentary The Unknown Marx Brothers that Julius was named "Groucho" simply because he was grouchy most or all of the time. Robert B. Weide, a director known for his knowledge of Marx Brothers history, said in Remarks On Marx, a documentary short included with the DVD of A Night at the Opera, that among the competing explanations he found this one the most believable. Steve Allen, in Funny People, said that the name made no sense; Groucho might have been impudent and impertinent, but not grouchy — at least not around Allen. However, at the very end of his life, Groucho finally admitted that Fisher had named him Groucho because he was the "moody one".^[25]

• The grouch bag: This explanation appears in Harpo's biography, was voiced by Chico in a TV appearance included on The Unknown Marx Brothers, and was also offered by George Fenneman, Groucho's sidekick on his TV game show, You Bet Your Life. A grouch bag was a small drawstring bag worn around the neck in which a traveler could keep money and other valuables so that it would be very difficult for anyone to steal them. Most of Groucho's friends and associates stated that Groucho was extremely stingy, especially after losing all his money in the 1929 stock market crash, so naming him for the grouch bag may have been a comment on this trait. Groucho, in chapter six of his first autobiography, insisted that this was not the case:

I kept my money in a 'grouch bag.' This was a small chamois bag that actors used to wear around their neck to keep other hungry actors from pinching their dough. Naturally, you're going to think that's where I got my name from. But that's not so. Grouch bags were worn on manly chests long before there was a Groucho.^[26]

• Groucho's explanation: Groucho himself insisted that he was named for a character in the comic strip, Knocko the Monk, which inspired the craze for nicknames ending in "o"; in fact, there was a character in that strip named "Groucho the Monk". However, he is the only Marx or Marx associate who defended this theory, and as he is not an unbiased witness, few biographers take the claim seriously.

Groucho himself was no help on this point; during his Carnegie Hall concert, when he was discussing the Brothers' names and when it came to his own, he said, "My name, of course, I never did understand." He goes on to mention the possibility that he was named after his unemployed uncle, Julius, who lived with his family. The family believed he was actually a rich uncle hiding a fortune. Groucho claims that he may have been named after him (perhaps by the family trying to get into the will). "And he finally died, and he left us his will, and in that will he left three razor blades, an 8-ball, a celluloid dicky, and he owed my father $85 beside."^[27]

Herbert was not nicknamed by Art Fisher, since he did not join the act until Gummo had departed. As with Groucho, three explanations exist for Herbert's name, "Zeppo":

• Harpo's explanation: Harpo said in Harpo Speaks! the brothers had named Herbert for Mr. Zippo, a chimpanzee that was part of another performer's act. Herbert found the nickname very unflattering, and when it came time for him to join the act, he put his foot down and refused to be called "Zippo." The brothers compromised on Zeppo.

• Chico's explanation: Chico never wrote an autobiography, and gave fewer interviews than his brothers, but his daughter, Maxine, in The Unknown Marx Brothers said that when the Marx Brothers lived in Chicago, a popular style of humor was the "Zeke and Zeb" joke, which made fun of slow-witted Midwesterners in much the same way Boudreaux and Thibodeaux jokes mock Cajuns and Ole and Lena jokes mock Minnesotans. One day, as Chico returned home, he found Herbert sitting on the fence. Herbert greeted him by saying "Hi, Zeke!" Chico responded with "Hi, Zeb!" and the name stuck. The brothers thereafter called him "Zeb," and when he joined the act, they floated the idea of "Zebbo," eventually preferring "Zeppo."

• Groucho's explanation: In a tape-recorded interview excerpted on The Unknown Marx Brothers, Groucho said Zeppo was so named because he was born when the first zeppelins started crossing the ocean. He also stated this in his Carnegie Hall concert, ca. 1972. The first zeppelin flew in July 1900, and Herbert was born seven months later in February 1901. However, the first transatlantic zeppelin flight was not until 1924, long after Herbert's birth.

Maxine Marx reported in The Unknown Marx Brothers that the brothers listed their real names (Julius, Leonard, Adolph, Milton and Herbert) on playbills and in programs, and only used the nicknames behind the scenes, until Alexander Woollcott overheard them calling one another by the nicknames; he asked them why they used their own ordinary real names publicly when they had such wonderful nicknames. They replied, "That wouldn't be dignified." Woollcott answered with a belly laugh. Since Woollcott did not meet the Marx Brothers until the premiere of I'll Say She Is, which was their first Broadway show, this would mean they used their real names throughout their vaudeville days, and that the name "Gummo" never appeared in print during his time in the act. Other sources report that the Marx Brothers did go by their nicknames during their vaudeville era, but briefly listed themselves by their given names when I'll Say She Is opened because they were worried that a Broadway audience would reject a vaudeville act if they were perceived as low class.^[28]

Hollywood[link]

Paramount[link]

The Marx Brothers' stage shows became popular just as Hollywood was changing to "talkies". They signed a contract with Paramount and embarked on their film career. Their first two released films (they had previously made — but not released — one short silent film titled Humor Risk) were adaptations of Broadway shows: The Cocoanuts (1929) and Animal Crackers (1930). Both were written by George S. Kaufman and Morrie Ryskind. Following these two feature-length films, they made a short film that was included in Paramount's twentieth anniversary documentary, The House That Shadows Built (1931), in which they adapted a scene from I'll Say She Is. Their third feature-length film, Monkey Business (1931), was their first that was not based on a stage production, and the only movie in which Harpo's voice is heard (he sings tenor from inside a barrel in the opening scene). Horse Feathers (1932), in which the brothers satirized the American college system and Prohibition, was their most popular film yet, and won them the cover of Time. It included a running gag from their stage work, where Harpo revealed having nearly everything in his coat. At various points in Horse Feathers Harpo pulls out of his coat: a wooden mallet, a fish, a coiled rope, a tie, a poster of a woman in her underwear, a cup of hot coffee, a sword; and, just after Groucho warns him that he "can't burn the candle at both ends," a candle burning at both ends. In another famous sketch, shown in Animal Crackers, Harpo drops a full banquet's worth of pilfered silverware out of his sleeve, followed by a coffeepot.

During this time, Chico and Groucho Marx starred in a radio comedy series, Flywheel, Shyster and Flywheel. Although the series was short lived, much of the story material developed for it was used for subsequent films starring the Brothers. Furthermore, the scripts and recordings were believed lost for decades until copies of the scripts were found in the 1980s in the Library of Congress and both published in a book and performed with Marx Brother impersonators for BBC Radio.

Their last Paramount film, Duck Soup (1933) — directed by the most highly regarded director they ever worked with, Leo McCarey — is the highest rated of the five Marx Brothers films to make the American Film Institute's "100 years ... 100 Movies" list. It did not do as well as Horse Feathers, but was the sixth-highest grosser of 1933. The film also led to a feud between the Marxes and the village of Fredonia, New York. Freedonia, of course, was the name of the fictional country in Duck Soup, and the city fathers wrote to Paramount and asked the studio to remove all references in the film to Freedonia because "it is hurting our town's image". Groucho fired back a sarcastic reply asking them to change the name of their town because "it's hurting our picture".

The Marx Brothers left Paramount because of disagreements over creative decisions and financial issues.

MGM, RKO, and United Artists[link]

Zeppo left the act to become an agent and went on to build with his brother Gummo one of the biggest talent agencies in Hollywood, helping the likes of Jack Benny and Lana Turner get their starts. Groucho and Chico did radio, and there was talk of returning to Broadway. At a bridge game with Chico, Irving Thalberg began discussing the possibility of the Marxes coming to Metro-Goldwyn-Mayer, and they signed, now known as "The Three Marx Brothers," or simply "The Marx Bros."

Unlike the free-for-all scripts at Paramount, Thalberg insisted on a strong story structure, making them into more sympathetic characters, interweaving their comedy with romantic plots and non-comic musical numbers, while the targets of their mischief were largely confined to clear villains. Thalberg was adamant that these scripts had to include a "low point" where all seems lost for both the Marxes and the romantic leads. In a June 13, 1969, interview with Dick Cavett, Groucho said that the two movies made with Thalberg (A Night at the Opera and A Day at the Races) were the best that they ever produced.

Marx Brothers by Yousuf Karsh, 1948

Another idea of Thalberg's was that before filming would commence on an upcoming picture, the Marx Brothers would try out its material on the vaudeville stage, working on comic timing and learning what earned a laugh and what did not.

The first film that the brothers shot with Thalberg was A Night at the Opera (1935), a satire on the world of opera, where the brothers help two young singers in love by throwing a production of Il Trovatore into chaos. The film (which includes a scene where they cram an absurd number of people into a tiny stateroom on a ship) was a great success, and was followed two years later by the even bigger hit A Day at the Races (1937), where the brothers cause mayhem in a sanitarium and at a horse race (this sequence includes Groucho and Chico's famous "Tootsie Frootsie Ice Cream" sketch). However, during shooting in 1936, Thalberg died suddenly, and without him, the brothers did not have an advocate at MGM.

After a short experience at RKO (Room Service, 1938), the Marx Brothers returned to MGM and made three more films, At the Circus (1939), Go West (1940) and The Big Store (1941). Prior to the release of The Big Store, the team announced their retirement from the screen, but Chico was in dire financial straits; to help settle his gambling debts, the Marx Brothers made another two films together, A Night in Casablanca (1946) and Love Happy (1949), both of them released by United Artists.

Later years[link]

From the 1940s onward, Chico and Harpo appeared separately and together in nightclubs and casinos. Chico also fronted a big band, the Chico Marx Orchestra (with 17-year-old Mel Tormé as a vocalist). Groucho began his solo career with You Bet Your Life, which ran from 1947 to 1961 on NBC radio and television. He also authored several books, including Groucho and Me (1959), Memoirs of a Mangy Lover (1964) and The Groucho Letters (1967).

Groucho and Chico briefly appeared together in a 1957 short film promoting the Saturday Evening Post entitled "Showdown at Ulcer Gulch," directed by animator Shamus Culhane, Chico's son-in-law. Groucho, Chico, and Harpo worked together (in separate scenes) in The Story of Mankind (1957). In 1959, the three began production of Deputy Seraph, a TV series starring Harpo and Chico as blundering angels, and Groucho (in every third episode) as their boss, the "Deputy Seraph." The project was abandoned when Chico was found to be uninsurable (and incapable of memorizing his lines) due to severe arteriosclerosis. On March 8 of that year, Chico and Harpo starred as bumbling thieves in The Incredible Jewel Robbery, a half-hour pantomimed episode of the General Electric Theater on CBS. Groucho made a cameo appearance—uncredited, because of constraints in his NBC contract—in the last scene, and delivered the only line of dialogue ("We won't talk until we see our lawyer!").

According to a September 1947 article in Newsweek, Groucho, Harpo, Chico and Zeppo all signed to appear as themselves in a biopic entitled The Life and Times of the Marx Brothers. In addition to being a non-fiction biography of the Marxes, the film would have also featured the brothers reenacting much of their previously unfilmed material from both their vaudeville and Broadway eras. The film, had it been made, would have been the first performance by the Brothers as a quartet since 1933.

The five brothers made only one television appearance together, in 1957, on an early incarnation of The Tonight Show called Tonight! America After Dark, hosted by Jack Lescoulie. Five years later (October 1, 1962) after Jack Paar's tenure, Groucho made a guest appearance to introduce the Tonight Show's new host, Johnny Carson.^[29]

Around 1960, the acclaimed director Billy Wilder considered writing and directing a new Marx Brothers film. Tentatively titled "A Day at the U.N.," it was to be a comedy of international intrigue set around the United Nations building in New York. Wilder had discussions with Groucho and Gummo, but the project was put on hold because of Harpo's ill-health and abandoned when Chico died in 1961.^[30]

In 1970, the four Marx Brothers had a brief reunion (of sorts) in the animated ABC television special The Mad, Mad, Mad Comedians, produced by Rankin-Bass animation (of Rudolph the Red-Nosed Reindeer fame). The special featured animated reworkings of various famous comedians' acts, including W. C. Fields, Jack Benny, George Burns, Henny Youngman, The Smothers Brothers, Flip Wilson, Phyllis Diller, Jack E. Leonard, George Jessel and the Marx Brothers. Most of the comedians provided their own voices for their animated counterparts, except for Fields and Chico Marx (both had died), and Zeppo Marx (who had left show business in 1933). Voice actor Paul Frees filled in for all three (no voice was needed for Harpo, who was also deceased). The Marx Brothers' segment was a reworking of a scene from their Broadway play I'll Say She Is, a parody of Napoleon which Groucho considered among the Brothers' funniest routines. The sketch featured animated representations, if not the voices, of all four brothers. Romeo Muller is credited as having written special material for the show, but the script for the classic "Napoleon Scene" was probably supplied by Groucho.

On January 16, 1977, the Marx Brothers were inducted into the Motion Picture Hall of Fame.

Many television shows and movies have used Marx Brothers references. Animaniacs and Tiny Toons, for example, have featured Marx Brothers jokes and skits. Hawkeye Pierce (Alan Alda) on M*A*S*H occasionally put on a fake nose and glasses, and, holding a cigar, did a Groucho impersonation to amuse patients recovering from surgery. Bugs Bunny also impersonated Groucho Marx in the 1947 cartoon Slick Hare and in a later cartoon he again impersonated Groucho hosting a TV show called You Beat Your Wife, asking Elmer Fudd if he had stopped beating his wife. Tex Avery's cartoon Hollywood Steps Out (1941) featured appearances by Harpo and Groucho. They also appeared, sometimes with Chico and Zeppo also caricatured, in cartoons starring Mickey Mouse, Flip the Frog and others. In the Airwolf episode 'Condemned', four anti-virus formulae for a deadly plague were named after the four Marx Brothers. In All In The Family, Rob Reiner often did imitations of Groucho, and Sally Struthers dressed as Harpo in one episode in which she (as Gloria Stivic) and Rob (as Mike Stivic) were going to a Marx Bros. film festival, with Reiner dressing as Groucho. Gabe Kaplan did many Groucho imitations on his sit-com Welcome Back, Kotter and Robert Hegyes sometimes imitated Chico on the show. In Woody Allen's film Hannah and Her Sisters(1986), Woody's character, after an unsuccessful suicide attempt is inspired to go on living after seeing a revival showing of Duck Soup. In Manhattan(1979), he names the Marx Bros. as something that makes life worth living. In Everyone Says I Love You(1996), he and Goldie Hawn dress as Groucho for a Marx Bros. celebration in France, and the song "Hooray for Captain Spaulding", from Animal Crackers, is performed, with various actors dressed as the brothers, striking poses famous to Marx fans. (The film itself is named after a song from Horse Feathers, a version of which plays over the opening credits.)

Also noteworthy is the fact that Harpo Marx appeared as himself in a sketch on I Love Lucy in which he and Lucille Ball reprised the mirror routine from Duck Soup, with Lucy dressed up as Harpo. Lucy had met the Marxes when she appeared in a supporting role in an earlier Marx Brothers film, Room Service. Chico once appeared on I've Got a Secret dressed up as Harpo; his secret was shown in a caption reading "I'm actually Chico Marx." Furthermore, it should also be noted that the Marx Brothers were also spoofed in the second act of the Broadway Review A Day in Hollywood/A Night in the Ukraine
