The guitar is a plucked string instrument, usually played with fingers or a pick. The guitar consists of a body with a rigid neck to which the strings, generally six in number, are attached. Guitars are traditionally constructed of various woods and strung with animal gut or, more recently, with either nylon or steel strings. Some modern guitars are made of polycarbonate materials. Guitars are made and repaired by luthiers. There are two primary families of guitars: acoustic and electric.

Acoustic guitars (and similar instruments) with hollow bodies have been in use for over a thousand years. There are three main types of modern acoustic guitar: the classical guitar (nylon-string guitar), the steel-string acoustic guitar, and the archtop guitar. The tone of an acoustic guitar is produced by the vibration of the strings, which is amplified by the body of the guitar, which acts as a resonating chamber. The classical guitar is often played as a solo instrument using a comprehensive fingerpicking technique.

Electric guitars, introduced in the 1930s, rely on an amplifier that can electronically manipulate tone. Early amplified guitars employed a hollow body, but a solid body was found more suitable. Electric guitars have had a continuing profound influence on popular culture. Guitars are recognized as a primary instrument in genres such as blues, bluegrass, country, flamenco, jazz, jota, mariachi, metal, reggae, rock, soul, and many forms of pop.

History

Before the development of the electric guitar and the use of synthetic materials, a guitar was defined as being an instrument having "a long, fretted neck, flat wooden soundboard, ribs, and a flat back, most often with incurved sides". The term is used to refer to a number of related instruments that were developed and used across Europe beginning in the 12th century and, later, in the Americas. These instruments are descended from ones that existed in ancient central Asia and India. For this reason guitars are distantly related to modern instruments from these regions, including the tanbur, the setar, and the sitar. The oldest known iconographic representation of an instrument displaying the essential features of a guitar is a 3,300 year old stone carving of a Hittite bard.

The modern word guitar, and its antecedents, have been applied to a wide variety of cordophones since ancient times and as such is the cause of confusion. The English word guitar, the German , and the French were adopted from the Spanish , which comes from the Andalusian Arabic , itself derived from the Latin , which in turn came from the Ancient Greek , and is thought to ultimately trace back to the Old Persian language. Tar means string in Persian.

Although the word guitar is descended from the Latin word cithara, the modern guitar itself is not generally believed to have descended from the Roman instrument. Many influences are cited as antecedents to the modern guitar. One commonly cited influence is of the arrival of the four-string oud, which was introduced by the invading Moors in the 8th century. Another suggested influence is the six-string Scandinavian lut (lute), which gained in popularity in areas of Viking incursions across medieval Europe. Often depicted in carvings c. 800 AD, the Norse hero Gunther (also known as Gunnar), played a lute with his toes as he lay dying in a snake-pit, in the legend of Siegfried. It is likely that a combination of influences led to the creation of the guitar; plucked instruments from across the Mediterranean and Europe were well known in Iberia since antiquity.

Two medieval instruments that were called "guitars" were in use by 1200: the (Moorish guitar) and the (Latin guitar). The guitarra moresca had a rounded back, wide fingerboard, and several soundholes. The guitarra Latina had a single soundhole and a narrower neck. By the 14th century the qualifiers "moresca" and "latina" had been dropped and these two cordophones were usually simply referred to as guitars.

The Spanish vihuela or (in Italian) "", a guitar-like instrument of the 15th and 16th centuries, is widely considered to have been a seminal influence in the development of the guitar. It had six courses (usually), lute-like tuning in fourths and a guitar-like body, although early representations reveal an instrument with a sharply cut waist. It was also larger than the contemporary four course guitars. By the late 15th century some vihuelas were played with a bow, leading to the development of the viol. By the sixteenth century the vihuela's construction had more in common with the modern guitar, with its curved one-piece ribs, than with the viols, and more like a larger version of the contemporary four-course guitars. The vihuela enjoyed only a short period of popularity in Spain and Italy during an era dominated elsewhere in Europe by the lute; the last surviving published music for the instrument appeared in 1576. Meanwhile the five-course baroque guitar, which was documented in Spain from the middle of the 16th century, enjoyed popularity, especially in Spain, Italy and France from the late 16th century to the mid 18th century. Confusingly, in Portugal, the word vihuela referred to the guitar, whereas guitarra meant the "Portuguese guitar", a variety of cittern.

Types

Guitars can be divided into two broad categories, acoustic and electric:

Acoustic guitars

There are several notable subcategories within the acoustic guitar group: classical and flamenco guitars; steel-string guitars, which include the flat-topped, or "folk," guitar; twelve-string guitars; and the arched-top guitar. The acoustic guitar group also includes unamplified guitars designed to play in different registers, such as the acoustic bass guitar, which has a similar tuning to that of the electric bass guitar.

Renaissance and Baroque guitars

:These are the gracile ancestors of the modern classical guitar. They are substantially smaller and more delicate than the classical guitar, and generate a much quieter sound. The strings are paired in courses as in a modern 12-string guitar, but they only have four or five courses of strings rather than six. They were more often used as rhythm instruments in ensembles than as solo instruments, and can often be seen in that role in early music performances. (Gaspar Sanz' Instrucción de Música sobre la Guitarra Española of 1674 constitutes the majority of the surviving solo corpus for the era.) Renaissance and Baroque guitars are easily distinguished because the Renaissance guitar is very plain and the Baroque guitar is very ornate, with ivory or wood inlays all over the neck and body, and a paper-cutout inverted "wedding cake" inside the hole.

Classical guitars

:These are typically strung with nylon strings, plucked with the fingers, played in a seated position and are used to play a diversity of musical styles including classical music. The classical guitar's wide, flat neck allows the musician to play scales, arpeggios, and certain chord forms more easily and with less adjacent string interference than on other styles of guitar. Flamenco guitars are very similar in construction, but are associated with a more percussive tone. In Mexico, the popular mariachi band includes a range of guitars, from the tiny requinto to the guitarrón, a guitar larger than a cello, which is tuned in the bass register. In Colombia, the traditional quartet includes a range of instruments too, from the small bandola (sometimes known as the Deleuze-Guattari, for use when traveling or in confined rooms or spaces), to the slightly larger tiple, to the full sized classical guitar. The requinto also appears in other Latin-American countries as a complementary member of the guitar family, with its smaller size and scale, permitting more projection for the playing of single-lined melodies. Modern dimensions of the classical instrument were established by the Spaniard Antonio de Torres Jurado (1817-1892).

Extended-range classical guitars

:An Extended-range classical guitar is a classical guitar with more than 6 strings, usually up to 13.

Flamenco guitars

:The flamenco guitar is similar to the classical guitar, but of lighter construction, with a cypress body and spruce top. Tuning pegs like those of a violin are traditional, although many modern flamenco guitars have machine heads. A distinguishing feature of all flamenco guitars is the tapping plates (golpeadores) glued to the table, to protect them against the taps with the fingernails that are an essential feature of the flamenco style.

:Many modern soloists (following the lead of Paco de Lucía) play what is called a flamenca negra, a hybrid of the flamenco and classical guitar constructions.

Flat-top (steel-string) guitars

:Similar to the classical guitar, however, within the varied sizes of the steel-stringed guitar the body size is usually significantly larger than a classical guitar, and has a narrower, reinforced neck and stronger structural design. The robust X-bracing typical of the steel-string was developed in the 1840s by German-American luthiers of whom C. F. Martin is the best known. Originally used on gut-strung instruments, the strength of the system allowed the guitar to withstand the additional tension of steel strings when this fortunate combination arose in the early 20th century. The steel strings produce a brighter tone, and according to many players, a louder sound. The acoustic guitar is used in many kinds of music including folk, country, bluegrass, pop, jazz, and blues. Many variations are possible from the roughly classical-sized OO and Parlour to the large Dreadnought and Jumbo. Ovation makes a modern variation, with a rounded back/side assembly molded from artificial materials.

Archtop guitars

:These are steel-string instruments in which the top (and often the back) of the instrument are carved from a solid billet in a curved rather than a flat shape; this violin-like construction is usually credited to the American Orville Gibson (1856-1918). Lloyd Loar of the Gibson Mandolin-Guitar Mfg. Co introduced the violin-inspired f-hole design now usually associated with archtop guitars, after designing a style of mandolin of the same type. The typical archtop guitar has a large, deep, hollow body whose form is much like that of a mandolin or violin family instrument. Nowadays, most archtops are equipped with magnetic pickups and are therefore both acoustic and electric. F-hole archtop guitars were immediately adopted upon their release by both jazz and country musicians and have remained particularly popular in jazz music, usually with flatwound strings.

Selmer-Maccaferri guitars

:These are usually played by those who follow the style of Django Reinhardt. It is an unusual-looking instrument, distinguished by a fairly large body with squarish bouts, and either a "D"-shaped or longitudinal oval soundhole. The strings are gathered at the tail like an archtop guitar, but the top is formed from thin spruce (like a flat-top or classical) forced into a shallow dome. It also has a wide fingerboard and slotted head like a nylon-string guitar. The loud volume and penetrating tone make it suitable for single-note soloing and it is frequently employed as a lead instrument in gypsy swing.

Resonator, resophonic or Dobro guitars

:All three principal types of resonator guitars were invented by the Slovak-American John Dopyera (1893-1988) for the National and Dobro (Dopyera Brothers) companies. Similar to the flat top guitar in appearance, but with a body that may be made of brass, nickel-silver, or steel as well as wood, the sound of the resonator guitar is produced by one or more aluminum resonator cones mounted in the middle of the top. The physical principle of the guitar is therefore similar to the loudspeaker. The original purpose of the resonator was to produce a very loud sound; this purpose has been largely superseded by electrical amplification, but the resonator guitar is still played because of its distinctive tone. Resonator guitars may have either one or three resonator cones. The method of transmitting sound resonance to the cone is either a "biscuit" bridge, made of a small piece of hardwood at the vertex of the cone (Nationals), or a "spider" bridge, made of metal and mounted around the rim of the (inverted) cone (Dobros). Three-cone resonators always use a specialized metal bridge. The type of resonator guitar with a neck with a square cross-section–called "square neck" or "Hawaiian"–is usually played face up, on the lap of the seated player, and often with a metal or glass slide. The round neck resonator guitars are normally played in the same fashion as other guitars, although slides are also often used, especially in blues.

Twelve-string guitars

:The twelve-string guitar usually has steel strings and is widely used in folk music, blues, and rock and roll. Rather than having only six strings, the 12-string guitar has six courses made up of two strings each, like a mandolin or lute. The highest two courses are tuned in unison, while the others are tuned in octaves. The 12-string guitar is also made in electric forms.

Russian guitars

:These seven-string acoustic guitars were the norm for Russian guitarists throughout the 19th and well into the 20th centuries. The Russian guitar is traditionally tuned to open G major.

Acoustic bass guitars

:These have steel strings or gut strings and often the same tuning as an electric bass guitar.

Guitarrón

:The guitarrón is a very large, deep-bodied Mexican 6-string acoustic bass played in mariachi bands. It is fretless with heavy gauge nylon strings, and is usually played by doubling notes at the octave, which is facilitated by the unusual tuning of A D G C E A.

Tenor guitars

:A number of classical guitarists call the Niibori prime guitar a "Tenor Guitar" on the grounds that it sits in pitch between the alto and the bass. Elsewhere the name is taken for a 4-string guitar with a scale length of 23" (585 mm)—about the same as a Terz Guitar. The tenor guitar is tuned in fifths, C G D A, as is the tenor banjo and the cello. It is generally accepted that the tenor guitar was created to allow a tenor banjo player to follow the fashion as it evolved from Dixieland Jazz towards the more progressive Jazz that featured guitar. It allows a tenor banjo player to provide a guitar-based rhythm section with little to learn. A small minority of players (such as Nick Reynolds of the Kingston Trio) close tuned the instrument to D G B E to produce a deep instrument that could be played with the 4-note chord shapes found on the top 4 strings of the guitar or ukulele. The deep pitch warrants the wide-spaced chords that the banjo tuning permits, and the close tuned tenor does not have the same full, clear sound.

Harp guitars

:Harp Guitars are difficult to classify as there are many variations within this type of guitar. They are typically rare and uncommon in the popular music scene. Most consist of a regular guitar, plus additional 'harp' strings strung above the six normal strings. The instrument is usually acoustic and the harp strings are usually tuned to lower notes than the guitar strings, for an added bass range. Normally there is neither fingerboard nor frets behind the harp strings. Some harp guitars also feature much higher pitch strings strung below the traditional guitar strings. The number of harp strings varies greatly, depending on the type of guitar and also the player's personal preference.The Pikasso guitar; 4 necks, 2 sound holes, 42 strings] and also the Oracle Harp Sympitar; 24 strings (with 12 sympathetic strings protruding through the neck) are modern examples.

Extended-range guitars

:For well over a century guitars featuring seven, eight, nine, ten or more strings have been used by a minority of guitarists as a means of increasing the range of pitch available to the player. Usually, it is bass strings that are added. Classical guitars with an extended range are useful for playing lute repertoire, some of which was written for lutes with more than six courses. A typical example is the modern 11 string archguitar, invented and played by Peter Blanchette.

Guitar battente

:The battente is smaller than a classical guitar, usually played with four or five metal strings. It is mainly used in Calabria (a region in southern Italy) to accompany the voice.

Electric guitars

Electric guitars can have solid, semi-hollow, or hollow bodies, and produce little sound without amplification. Electromagnetic pickups convert the vibration of the steel strings into signals, which are fed to an amplifier through a cable or radio transmitter. The sound is frequently modified by other electronic devices or the natural distortion of valves (vacuum tubes) in the amplifier. There are two main types of magnetic pickups, single and double coil (or humbucker), each of which can be passive or active. The electric guitar is used extensively in jazz, blues, R & B, and rock and roll. The first successful magnetic pickup for a guitar was invented by George Beauchamp, and incorporated into the 1931 Ro-Pat-In (later Rickenbacker) "Frying Pan" lap steel; other manufacturers, notably Gibson, soon began to install pickups in archtop models. After World War II the completely solid-body electric was popularized by Gibson in collaboration with Les Paul, and independently by Leo Fender of Fender Music. The lower fretboard action (the height of the strings from the fingerboard), lighter (thinner) strings, and its electrical amplification lend the electric guitar to techniques less frequently used on acoustic guitars. These include tapping, extensive use of legato through pull-offs and hammer-ons (also known as slurs), pinch harmonics, volume swells, and use of a tremolo arm or effects pedals.

The first electric guitarist of note to use a seven-string guitar was jazz guitarist George Van Eps, who was a pioneer of this instrument. Solid body seven-strings were popularized in the 1980s and 1990s in part due to the release of the Ibanez Universe guitar, endorsed by Steve Vai. Other artists go a step further, by using an eight-string guitar with two extra low strings. Although the most common seven-string has a low B string, Roger McGuinn (of The Byrds and Rickenbacker) uses an octave G string paired with the regular G string as on a 12-string guitar, allowing him to incorporate chiming 12-string elements in standard six-string playing. In 1982 Uli Jon Roth developed the "Sky Guitar", with a vastly extended number of frets, which was the first guitar to venture into the upper registers of the violin. Roth's seven-string and 33-fret "Mighty Wing" guitar features a six-octave range.

The electric bass guitar is similar in tuning to the traditional double bass viol. Hybrids of acoustic and electric guitars are also common. There are also more exotic varieties, such as guitars with two, three, or rarely four necks, all manner of alternate string arrangements, fretless fingerboards (used almost exclusively on bass guitars, meant to emulate the sound of a stand-up bass), 5.1 surround guitar, and such.

Some electric guitar and electric bass guitar models feature piezoelectric pickups, which function as transducers to provide a sound closer to that of an acoustic guitar with the flip of a switch or knob, rather than switching guitars. Those that combine piezoelectric pickups and magnetic pickups are sometimes known as hybrid guitars.

Construction and components

General

Guitars can be constructed to meet the demands of both left and right-handed players. Traditionally the dominant hand is assigned the task of plucking or strumming the strings. For the majority of people this entails using the right hand. This is because musical expression (dynamics, tonal expression, color, etc.) is largely determined by the plucking hand, while the fretting hand is assigned the lesser mechanical task of depressing and gripping the strings. This is similar to the convention of the violin family of instruments where the right hand controls the bow. Left-handed players generally choose a left-handed (mirror) instrument, although some play in a standard right-handed manner, others play a standard right-handed guitar reversed, and still others (for example Jimi Hendrix) play a right-handed guitar strung in reverse. This last configuration differs from a true left-handed guitar in that the saddle is normally angled in such a way that the bass strings are slightly longer than the treble strings to improve intonation. Reversing the strings therefore reverses the relative orientation of the saddle (negatively affecting intonation), although in Hendrix' case this is believed to have been an important element in his unique sound.

Headstock

The headstock is located at the end of the guitar neck furthest from the body. It is fitted with machine heads that adjust the tension of the strings, which in turn affects the pitch. Traditional tuner layout is "3+3" in which each side of the headstock has three tuners (such as on Gibson Les Pauls). In this layout, the headstocks are commonly symmetrical. Many guitars feature other layouts as well, including six-in-line (featured on Fender Stratocasters) tuners or even "4+2" (Ernie Ball Music Man). However, some guitars (such as Steinbergers) do not have headstocks at all, in which case the tuning machines are located elsewhere, either on the body or the bridge.

Nut

The nut is a small strip of bone, plastic, brass, corian, graphite, stainless steel, or other medium-hard material, at the joint where the headstock meets the fretboard. Its grooves guide the strings onto the fretboard, giving consistent lateral string placement. It is one of the endpoints of the strings' vibrating length. It must be accurately cut, or it can contribute to tuning problems due to string slippage, and/or string buzz. To reduce string friction in the nut, which can adversely affect tuning stability, some guitarists fit a roller nut. Some instruments use a zero fret just in front of the nut. In this case the nut is used only for lateral alignment of the strings, the string height and length being dictated by the zero fret.

Fretboard

Also called the fingerboard, the fretboard is a piece of wood embedded with metal frets that comprises the top of the neck. It is flat on classical guitars and slightly curved crosswise on acoustic and electric guitars. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which the fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Most modern guitars feature a 12" neck radius, while older guitars from the 1960s and 1970s usually feature a 6-8" neck radius. Pinching a string against the fretboard effectively shortens the vibrating length of the string, producing a higher pitch. Fretboards are most commonly made of rosewood, ebony, maple, and sometimes manufactured or composite materials such as HPL or resin. See below on section "Neck" for the importance of the length of the fretboard in connection to other dimensions of the guitar.

Frets

Frets are metal strips (usually nickel alloy or stainless steel) embedded along the fretboard and located at exact points that divide the scale length in accordance with a specific mathematical formula. Pressing a string against a fret determines the strings' vibrating length and therefore its resultant pitch. The pitch of each consecutive fret is defined at a half-step interval on the chromatic scale. Standard classical guitars have 19 frets and electric guitars between 21 to 24 frets, although guitars have been made with as many as 27 frets.

Frets are laid out to a mathematical ratio that results in equal tempered division of the octave. The ratio of the spacing of two consecutive frets is the twelfth root of two. The twelfth fret divides the scale length in two exact halves and the 24th fret position divides the scale length in half yet again. Every twelve frets represents one octave. In practice, luthiers determine fret positions using the constant 17.817, which is derived from the twelfth root of two (17.817 = (1-2^-1/12)⁻¹). The scale length divided by this value yields the distance from the nut to the first fret. That distance is subtracted from the scale length and the result is divided in two sections by the constant to yield the distance from the first fret to the second fret. Positions for the remainder of the frets are calculated in like manner. Actual fret spacing does not use this exact value; the fret spacing on the fretboard was also done by trial and error (testing) method over the ages.

There are several different fret gauges, which can be fitted according to player preference. Among these are "jumbo" frets, which have much thicker gauge, allowing for use of a slight vibrato technique from pushing the string down harder and softer. "Scalloped" fretboards, where the wood of the fretboard itself is "scooped out" between the frets allows a dramatic vibrato effect. Fine frets, much flatter, allow a very low string-action but require other conditions such as curvature of the neck to be well maintained to prevent buzz.

On steel-string guitars, frets are eventually bound to wear down; when this happens, frets can be replaced or, to a certain extent, leveled, polished, recrowned, or reshaped as required.

Truss rod

The truss rod is a metal rod that runs along the inside of the neck. It is used to correct changes to the neck's curvature caused by the neck timbers aging, changes in humidity or to compensate for changes in the tension of strings. The tension of the rod and neck assembly is adjusted by a hex nut or an allen-key bolt on the rod, usually located either at the headstock, sometimes under a cover, or just inside the body of the guitar underneath the fretboard and accessible through the sound hole. Some truss rods can only be accessed by removing the neck. The truss rod counteracts the immense amount of tension the strings place on the neck, bringing the neck back to a straighter position. Turning the truss rod clockwise tightens it, counteracting the tension of the strings and straightening the neck or creating a backward bow. Turning the truss rod counter-clockwise loosens it, allowing string tension to act on the neck and creating a forward bow. Adjusting the truss rod affects the intonation of a guitar as well as the height of the strings from the fingerboard, called the action. Some truss rod systems, called "double action" truss systems, tighten both ways, allowing the neck to be pushed both forward and backward (standard truss rods can only be released to a point beyond which the neck is no longer compressed and pulled backward).

Classical guitars do not require truss rods as their nylon strings exert a lower tensile force with lesser potential to cause structural problems. However their necks are often reinforced with a strip of harder wood, such as an ebony strip running down the back of a cedar neck. There is no tension adjustment on this form of reinforcement.

Inlays

Inlays are visual elements set into the exterior surface of a guitar. The typical locations for inlay are on the fretboard, headstock, and on acoustic guitars around the soundhole, known as the rosette. Inlays range from simple plastic dots on the fretboard to intricate works of art covering the entire exterior surface of a guitar (front and back). Some guitar players have used LEDs in the fretboard to produce a unique lighting effects onstage.

Fretboard inlays are most commonly shaped like dots, diamond shapes, parallelograms, or large blocks in between the frets. Dots are usually inlaid into the upper edge of the fretboard in the same positions, small enough to be visible only to the player. These usually appear on the odd numbered frets, but also on the 12th fret (the one octave mark) instead of the 11th and 13th frets. Some older or high-end instruments have inlays made of mother of pearl, abalone, ivory, coloured wood or other exotic materials and designs. Simpler inlays are often made of plastic or painted. High-end classical guitars seldom have fretboard inlays as a well trained player is expected to know his or her way around the instrument.

In addition to fretboard inlay, the headstock and soundhole surround are also frequently inlaid. The manufacturer's logo or a small design is often inlaid into the headstock. Rosette designs vary from simple concentric circles to delicate fretwork mimicking the historic rosette of lutes. Bindings that edge the finger and sound boards are sometimes inlaid. Some instruments have a filler strip running down the length and behind the neck, used for strength and/or to fill the cavity through which the trussrod was installed in the neck.

Elaborate inlays are a decorative feature of many limited edition, high-end and custom-made guitars. Guitar manufacturers often release such guitars to celebrate significant or historic milestones.

Neck

A guitar's frets, fretboard, tuners, headstock, and truss rod, all attached to a long wooden extension, collectively constitute its neck. The wood used to make the fretboard usually differs from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used (see Tuning), and the ability of the neck to resist bending (see Truss rod) is important to the guitar's ability to hold a constant pitch during tuning or when strings are fretted. The rigidity of the neck with respect to the body of the guitar is one determinant of a good instrument versus a poor one. The shape of the neck can also vary, from a gentle "C" curve to a more pronounced "V" curve. There are many different types of neck profiles available, giving the guitarist many options. Some aspects to consider in a guitar neck may be the overall width of the fingerboard, scale (distance between the frets), the neck wood, the type of neck construction (for example, the neck may be glued in or bolted on), and the shape (profile) of the back of the neck. Other type of material used to make guitar necks are graphite (Steinberger guitars), aluminium (Kramer Guitars, Travis Bean and Veleno guitars), or carbon fiber (Modulus Guitars and ThreeGuitars).

Double neck electric guitars have two necks, allowing the musician to quickly switch between guitar sounds.

Neck joint or "Heel"

This is the point at which the neck is either bolted or glued to the body of the guitar. Almost all acoustic steel-string guitars, with the primary exception of Taylors, have glued (otherwise known as set) necks, while electric guitars are constructed using both types. Most classical guitars have a neck and headblock carved from one piece of wood, known as a "Spanish heel."

Commonly used set neck joints include mortise and tenon joints (such as those used by CF Martin & Co.), dovetail joints (also used by CF Martin on the D-28 and similar models) and Spanish heel neck joints, which are named after the shoe they resemble and commonly found in classical guitars. All three types offer stability. Bolt-on necks, though they are historically associated with cheaper instruments, do offer greater flexibility in the guitar's set-up, and allow easier access for neck joint maintenance and repairs.

Another type of neck, only available for solid body electric guitars, is the neck-through-body construction. These are designed so that everything from the machine heads down to the bridge are located on the same piece of wood. The sides (also known as wings) of the guitar are then glued to this central piece. Some luthiers prefer this method of construction as they claim it allows better sustain of each note. Some instruments may not have a neck joint at all, having the neck and sides built as one piece and the body built around it.

Strings

The standard guitar has six strings but four-, seven-, eight-, nine-, ten-, eleven-, twelve-, thirteen- and eighteen-string guitars are also available.

Classical and flamenco guitars historically used gut strings but these have been superseded by polymer materials, such as nylon and fluorocarbon.

Modern guitar strings are constructed of metal, polymers, or animal or plant product materials. Instruments utilising "steel" strings may have strings made of alloys incorporating steel, nickel or phosphor bronze. Bass strings for both instruments are wound rather than monofilament.

Body (acoustic guitar)

In acoustic guitars, string vibration is transmitted through the bridge and saddle to the body via sound board. The sound board is typically made of tone woods such as spruce or cedar. Timbers for tone woods are chosen for both strength and ability to transfer mechanical energy from the strings to the air within the guitar body. Sound is further shaped by the characteristics of the guitar body's resonant cavity.

In electric guitars, transducers known as pickups convert string vibration to an electric signal, which in turn is amplified and fed to speakers, which vibrate the air to produce the sounds we hear. Nevertheless, the body of the electric guitar still performs a role in shaping the resultant tonal signature.

In an acoustic instrument, the body of the guitar is a major determinant of the overall sound quality. The guitar top, or soundboard, is a finely crafted and engineered element made of tonewoods such as spruce and red cedar. This thin piece of wood, often only 2 or 3 mm thick, is strengthened by differing types of internal bracing. The top is considered by many luthiers to be the dominant factor in determining the sound quality. The majority of the instrument's sound is heard through the vibration of the guitar top as the energy of the vibrating strings is transferred to it.

Body size, shape and style has changed over time. 19th century guitars, now known as salon guitars, were smaller than modern instruments. Differing patterns of internal bracing have been used over time by luthiers. Torres, Hauser, Ramirez, Fleta, and C.F. Martin were among the most influential designers of their time. Bracing not only strengthens the top against potential collapse due to the stress exerted by the tensioned strings, but also affects the resonance characteristics of the top. The back and sides are made out of a variety of timbers such as mahogany, Indian rosewood and highly regarded Brazilian rosewood (Dalbergia nigra). Each one is primarily chosen for their aesthetic effect and can be decorated with inlays and purfling.

The body of an acoustic guitar has a sound hole through which sound projects. The sound hole is usually a round hole in the top of the guitar under the strings. Air inside the body vibrates as the guitar top and body is vibrated by the strings, and the response of the air cavity at different frequencies is characterised, like the rest of the guitar body, by a number of resonance modes at which it responds more strongly.

Instruments with larger areas for the guitar top were introduced by Martin in an attempt to create louder volume levels. The popularity of the larger "dreadnought" body size amongst acoustic performers is related to the greater sound volume produced.

Body (electric guitar)

Most electric guitar bodies are made of wood, and include a plastic pick guard. Boards wide enough to use as a solid body are very expensive due to the worldwide depletion of hardwood stock since the 70's, so the wood is rarely one solid piece. Most bodies are made of two pieces of wood with some of them including a seam running down the centre line of the body. The most common woods used for electric guitar body construction include maple, basswood, ash, poplar, alder, and mahogany. Many bodies consist of good sounding but inexpensive woods, like ash, with a "top", or thin layer of another, more attractive wood (such as maple with a natural "flame" pattern) glued to the top of the basic wood. Guitars constructed like this are often called "flame tops". The body is usually carved or routed to accept the other elements, such as the bridge, pickup, neck, and other electronic components. Most electrics have a polyurethane or nitrocellulose lacquer finish. Other alternative materials to wood, are used in guitar body construction. Some of these include carbon composites, plastic material (such as polycarbonate), and aluminum alloys.

Pickups

Pickups are transducers attached to a guitar that detect (or "pick up") string vibrations and convert the mechanical energy of the string into electrical energy. The resultant electrical signal can then be electronically amplified. The most common type of pickup is electromagnetic in design. These contain magnets that are tightly wrapped in a coil, or coils, of copper wire. Such pickups are usually placed right underneath the guitar strings. Electromagnetic pickups work on the same principles and in a similar manner to an electrical generator. The vibration of the strings causes a small voltage to be created in the coils surrounding the magnets; this signal voltage is later amplified.

Traditional electromagnetic pickups are either single-coil or double-coil. Single-coil pickups are susceptible to noise induced from electric fields, usually mains-frequency (60 or 50 hertz) hum. The introduction of the double-coil humbucker in the mid-1950s did away with this problem through the use of two coils, one of which is wired in a reverse polarity orientation.

The types and models of pickups used can greatly affect the tone of the guitar. Typically, humbuckers, which are two magnet–coil assemblies attached to each other are traditionally associated with a heavier sound. Single-coil pickups, one magnet wrapped in copper wire, are used by guitarists seeking a brighter, twangier sound with greater dynamic range.

Modern pickups are tailored to the sound desired. A commonly applied approximation used in selection of a pickup is that less wire (lower DC resistance) = brighter sound, more wire = "fat" tone. Other options include specialized switching that produces coil-splitting, in/out of phase and other effects. Guitar circuits are either active, needing a battery to power their circuit, or, as in most cases, equipped with a passive circuit.

Fender Stratocaster type guitars generally utilize three single-coil pickups, while most Gibson Les Paul types use humbucker pickups.

Piezoelectric, or piezo, pickups represent another class of pickup. These employ piezoelectricity to generate the musical signal and are popular in hybrid electro-acoustic guitars. A crystal is located under each string, usually in the saddle. When the string vibrates, the shape of the crystal is distorted, and the stresses associated with this change produce tiny voltages across the crystal that can be amplified and manipulated.

Some piezo-equipped guitars use what is known as a hexaphonic pickup. "Hex" is a prefix meaning six. In a hexaphonic pickup separate outputs are obtained from discrete piezoelectric pickups for each of the six strings. This arrangement allows the signal to be easily modified by on-board modelling electronics, as in the Line 6 Variax brand of electric guitars; the guitars allow for a variety of sounds to be obtained by digitally manipulating the signal. This allows a guitar to mimic many vintage models of guitar, as well as output alternate tunings without the need to adjust the strings.

Another use for hexaphonic pickups is to send the output signals to a MIDI interpretation device, which determines the note pitch, duration, attack and decay characteristics and so forth. The MIDI (Musical Instrument Digital Interface) interpreter then sends the note information to a sound bank device. The resulting sound can closely mimic numerous types of instruments. The MIDI setup can also enable the guitar to be used as a game controller (i.e. Rock Band Squier) or as an instructional tool, as with the Fretlight Guitar.

Electronics

On guitars that have them, these components and the wires that connect them allow the player to control some aspects of the sound like volume or tone. These at their simplest consist of passive components such as potentiometers and capacitors, but may also include specialized integrated circuits or other active components requiring batteries for power, for preamplification and signal processing, or even for assistance in tuning. In many cases the electronics have some sort of shielding to prevent pickup of external interference and noise.

Lining, binding, and purfling

The top, back and ribs of an acoustic guitar body are very thin (1–2 mm), so a flexible piece of wood called lining is glued into the corners where the rib meets the top and back. This interior reinforcement provides 5 to 20 mm of solid gluing area for these corner joints. Solid linings are often used in classical guitars, while kerfed lining is most often found in steel string acoustics. Kerfed lining is also called kerfing (because it is scored, or kerfed to allow it to bend with the shape of the rib).

During final construction, a small section of the outside corners is carved or routed out and filled with binding material on the outside corners and decorative strips of material next to the binding, which are called purfling. This binding serves to seal off the end grain of the top and back. Purfling can also appear on the back of an acoustic guitar, marking the edge joints of the two or three sections of the back.

Binding and purfling materials are generally made of either wood or plastic.

Bridge

The main purpose of the bridge on an acoustic guitar is to transfer the vibration from the strings to the soundboard, which vibrates the air inside of the guitar, thereby amplifying the sound produced by the strings.

On all electric, acoustic and original guitars, the bridge holds the strings in place on the body. There are many varied bridge designs. There may be some mechanism for raising or lowering the bridge saddles to adjust the distance between the strings and the fretboard (action), and/or fine-tuning the intonation of the instrument. Some are spring-loaded and feature a "whammy bar", a removable arm that lets the player modulate the pitch by changing the tension on the strings. The whammy bar is sometimes also referred to as a "tremolo bar" (see Tremolo for further discussion of this term—the effect of rapidly changing pitch produced by a whammy bar is more correctly called "vibrato"). Some bridges also allow for alternate tunings at the touch of a button.

On almost all modern electric guitars, the bridge has saddles which are adjustable for each string so that intonation stays correct up and down the neck. If the open string is in tune but sharp or flat when frets are pressed, the bridge saddle position can be adjusted with a screwdriver or hex key to remedy the problem. In general, flat notes are corrected by moving the saddle forward and sharp notes by moving it backwards. On an instrument correctly adjusted for intonation, the actual length of each string from the nut to the bridge saddle is slightly but measurably longer than the scale length of the instrument. This additional length is called compensation, which flattens all notes a bit to compensate for the sharping of all fretted notes caused by stretching the string during fretting.

Saddle

The saddle of a guitar refers to the part of the bridge that physically supports the strings. It may be one piece ( typically on acoustic guitars) or separate pieces, one for each string ( electric guitars and basses). The saddle's basic purpose is to provide the end point for the string's vibration at the correct location for proper intonation, and on acoustic guitars to transfer the vibrations through the bridge into the top wood of the guitar. Saddles are typically made of plastic or bone for acoustic guitars, though synthetics and some exotic animal tooth variations (e.g. fossilized tooth, ivory, etc. ) have become popular with some players. Electric guitar saddles are typically metal, though some synthetic saddles are available.

Pickguard

Also known as a scratchplate. This is usually a piece of laminated plastic or other material that protects the finish of the top of the guitar from damage due to the use of a plectrum or fingernails. Electric guitars sometimes mount pickups and electronics on the pickguard. It is a common feature on steel-string acoustic guitars. Vigorous performance styles such as flamenco, which can involve the use of the guitar as a percussion instrument, call for a scratchplate to be fitted to nylon-string instruments.

Whammy Bar (Tremolo Arm)

Many electric guitars are fitted with a vibrato and pitch bend device known as a "tremolo bar (or arm)", "sissy bar", "wang bar", "slam handle", "whammy handle", and "whammy bar". The latter two terms led stompbox manufacturers to use the term 'whammy' in coming up with a pitch raising effect introduced by popular guitar effects pedal brand Digitech.

The tremolo arm is common enough that there is a technical term, hard tail, for a guitar without one.

Leo Fender, who did much to create the electric guitar, also created much confusion over the meaning of the terms "tremolo" and "vibrato" by the naming the "tremolo" unit on many of his guitars and also the "vibrato" unit on his "Vibrolux" amps. In general, vibrato is a variation in pitch, whereas tremolo is a variation in volume, so the tremolo bar is actually a vibrato bar and the "Vibrolux" amps actually had a tremolo effect. However, following Fender's example, electric guitarists traditionally reverse these meanings when speaking of hardware devices and the effects they produce. See vibrato unit for a more detailed discussion, and tremolo arm for more of the history.

Another type of pitch bender is the B-Bender, a spring and lever device mounted in an internal cavity of a solid body electric, guitar that allows the guitarist to bend just the B string of the guitar using a lever connected to the strap handle of the guitar. The resulting pitch bend is evocative of the sound of the pedal steel guitar.

Guitar strap

A guitar strap is a strip of fabric with a leather or synthetic leather piece on each end. It is made to hold a guitar via the shoulders, at an adjustable length to suit the position favoured by the guitarist.

Guitars have varying accommodations for attaching a strap. The most common are strap buttons, also called strap pins, which are flanged steel posts anchored to the guitar with screws. Two strap buttons come pre-attached to virtually all electric guitars, and many steel-string acoustic guitars. Strap buttons are sometimes replaced with "strap locks" which connect the guitar to the strap more securely.

The lower strap button is usually located at the bottom (bridge end) of the body. The upper strap button is usually located near or at the top (neck end) of the body: on the upper body curve, at the tip of the upper "horn" (on a double cutaway), or at the neck joint (heel). Some electrics, especially those with odd-shaped bodies, have one or both strap buttons on the back of the body. Some Steinberger electric guitars, owing to their minimalist and lightweight design, have both strap buttons at the bottom of the body. Rarely, on some acoustics, the upper strap button is located on the headstock.

Some acoustic and classical guitars only have a single strap button at the bottom of the body—the other end must be tied onto the headstock, above the nut and below the machine heads.

Some acoustic and classical guitars come with no strap buttons at all. In this case, one or two strap buttons can usually be added to the guitar, or a "classical guitar strap" (also called a "guitar harness" or "neck strap") can be used, which supports the guitar by hooking into the sound hole.

Self-tuning guitars

Self-tuning guitars are computerized guitars programmed to tune themselves. The Gibson Robot Guitar, released in 2007, is often mistaken as the first of this kind, but was preceded by the Transperformance system by at least 20 years. Gibson has also released a second, self-tuning model called the Dark Fire.

Tuning

The guitar is a transposing instrument. Its pitch sounds one octave lower than it is notated on a score.

A variety of tunings may be used. The most common tuning, known as "Standard Tuning," has the strings tuned from a low E, to a high E, traversing a two octave range—EADGBE. When all strings are played open the resulting chord is an Em7/add11.

The pitches are as follows:

E₄ B₃ G₃ D₃ A₂ E₂

String !! Scientific pitch notation	Scientific pitch !! Helmholtz pitch	Interval (music)>Interval from middle C
first	|	e'	major third above	329.63 Hz
second	|	b	minor second below	246.94 Hz
third	|	g	perfect fourth below	196.00 Hz
fourth	|	d	minor seventh below	146.83 Hz
fifth	|	A	minor tenth below	110 Hz
sixth	|	E	minor thirteenth below	82.41 Hz

The table below shows a pitch's name found over the six strings of a guitar in standard tuning, from the nut (zero), to the twelfth fret.

A guitar using this tuning can tune to itself using the fact, with a single exception, that the 5th fret on one string is the same note as the next open string; that is, a 5th-fret note on the sixth string is the same note as the open fifth string. The exception is the interval between the second and third strings, in which the 4th-fret note on the third string is equivalent to the open second string.

Standard tuning has evolved to provide a good compromise between simple fingering for many chords and the ability to play common scales with minimal left hand movement. Uniquely, the guitar's tuning allows for repeatable patterns, which also facilitates the ease of playing common scales. There are also a variety of commonly used alternate tunings. Most of these are open tunings, i.e., the unfretted strings produce a simple chord, such as a G Major chord. Many open tunings, where all of the strings are tuned to a similar note or chord, are popular for slide guitar playing. Alternate tunings are used for two main reasons: the ease of playing and the variation in tone that can be achieved.

Many guitarists use a long established, centuries-old tuning variation where the lowest string is 'dropped' down a whole tone. Known as Drop-D (or dropped D) tuning it is, from low to high, DADGBE. This allows for open string tonic and dominant basses in the keys of D and D minor. It also enables simple fifths (powerchords) to be more easily played. Eddie Van Halen sometimes uses a device known as a 'D Tuna,' which he patented. It is a small lever, attached to the fine tuner of the 6th string on a Floyd Rose tremolo, which allows him to easily drop that string from E to D. Many contemporary rock bands retune all strings by several semi-tones, making, for example, Drop-C or Drop-B tunings, However this terminology is inconsistent with that of "drop-D" as "drop-D" refers to dropping a single string to the named pitch. Often these new tunings are also simply referred to as the "Standard" of the note in question e.g.–"D Standard" (DGcfad').

Some guitarists tune in straight fourths, avoiding the major third between the third and second strings. While this makes playing major and minor triads slightly more difficult, it facilitated playing chords with more complicated extended structures. One proponent of the straight fourth tuning (EADGCF) is Stanley Jordan.

As with all stringed instruments a large number of scordatura are possible on the guitar. A common form of scordatura involves tuning the 3rd string to F to mimic the standard tuning of the lute, especially when playing renaissance repertoire originally written for the lute.

Guitar accessories

Though a guitar may be played on its own, there are a variety of common accessories used for holding and playing the guitar.

Capotasto

A capo (short for capotasto) is used to change the pitch of open strings. Capos are clipped onto the fret board with the aid of spring tension, or in some models, elastic tension. To raise the guitar's pitch by one semitone, the player would clip the capo onto the fret board just below the first fret. Its use allows players to play in different keys without having to change the chord formations they use. Because of the ease with which they allow guitar players to change keys, they are sometimes referred to as "cheaters" or the "hillbilly crutch." Classical performers are known to use them to enable modern instruments to match the pitch of historical instruments such as the renaissance lute.

Slides

A slide, (neck of a bottle, knife blade or round metal bar) used in blues and rock to create a glissando or 'Hawaiian' effect. The necks of bottles were often used in blues and country music. Modern slides are constructed of glass, plastic, ceramic, chrome, brass or steel, depending on the weight and tone desired. An instrument that is played exclusively in this manner, (using a metal bar) is called a steel guitar or pedal steel. Slide playing to this day is very popular in blues music and country music. Some slide players use a so called Dobro guitar.

Some performers that have become famous for playing slide are Robert Johnson, Elmore James, Ry Cooder, George Harrison, Bonnie Raitt, Derek Trucks, Warren Haynes, Duane Allman, Muddy Waters, Rory Gallagher, and George Thorogood.

Plectrum

A "guitar pick" or "plectrum" is a small piece of hard material generally held between the thumb and first finger of the picking hand and is used to "pick" the strings. Though most classical players pick with a combination of fingernails and fleshy fingertips, the pick is most often used for electric and steel-string acoustic guitars. Though today they are mainly plastic, variations do exist, such as bone, wood, steel or tortoise shell. Tortoise shell was the most commonly used material in the early days of pick-making, but as tortoises and turtles became endangered, the practice of using their shells for picks or anything else was banned. Tortoise-shell picks made before the ban are often coveted for a supposedly superior tone and ease of use, and their scarcity has made them valuable.

Picks come in many shapes and sizes. Picks vary from the small jazz pick to the large bass pick. The thickness of the pick often determines its use. A thinner pick (between .2 and .5 mm) is usually used for strumming or rhythm playing, whereas thicker picks (between .7 and 1.5+ mm) are usually used for single-note lines or lead playing. The distinctive guitar sound of Billy Gibbons is attributed to using a quarter or peso as a pick. Similarly, Brian May is known to use a sixpence coin as a pick. David Persons is known for using old credit cards, cut to the correct size, as plectrums.

Thumb picks and finger picks that attach to the finger tips are sometimes employed in finger-picking styles on steel strings. These allow the fingers and thumb to operate independently, whereas a flat pick requires the thumb and one or two fingers to manipulate.

Edison Koon-Hei Chen (born 7 October 1980) is a Hong Kong Chinese film actor, rapper, Cantopop singer, model, record producer, fashion designer, and a pop icon. Chen is also the founder of CLOT Inc., and the CEO of Clot Media Division Limited. His native language is English, he is able to speak and sing Cantonese and Mandarin and also speaks conversational Japanese, which allows him to be a part of multiple entertainment industries around the world. On 21 February 2008 he publicly announced that he intended to step away "indefinitely" from the Hong Kong entertainment industry due to the sex photo scandal in 2008. However, he returned to the industry in 2010 and he stated "indefinitely" could mean 5 minutes or 2000 years.

Early life

Chen was born in Vancouver, British Columbia, Canada to parents (father is businessman Edward Chen) of Chinese and 1/8 Portuguese descent. He was a student at R.C. Palmer Secondary School in Richmond, British Columbia and also attended Hong Kong International School. He was in the same tenth grade class as fellow actor Nicholas Tse.

Career

Film

In 1999, a talent scout approached Chen while he was clubbing with friends in Hong Kong. He asked him to film a commercial. He was at the age of 19. From then on, his career began with the Japanese film Dead or Alive 2: Birds. He made his Hong Kong film debut in the film Gen-Y Cops in 2000. He starred in many popular films including Infernal Affairs, Infernal Affairs II, Initial D and Dog Bite Dog. His latest film is Trivial Matters. Determined to expand his horizons to countries around the world, he also starred in the Japanese drama Under the Same Moon. On October 28, during a fashion event in Beijing, Edison Chen announced that he will be starring in Initial D 2. The filming of the movie is scheduled to begin in 2011.

Music

In 2000, at the age of 20, Chen landed a record deal with Emperor Entertainment Group. It took him a number of successful album releases before he was given the opportunity to produce a hip hop album. His first hip-hop release was in February 2004, called Please Steal This Album backed by MC Yan and Singaporean musician Hanjin Chen. Several singles from the album topped local pop charts. Chen mentioned the difficulty of fitting in Hong Kong, where it is dominated by cantopop, but said that hip hop has a great potential.

He is featured on M-Flo's album, Cosmicolor, on the track "LOVE ME, HATE THE GAME" with Chan, Thaitanium and Ryohei Yamamoto.

After Chen's comeback in late 2009 he began work on his next album titled "CONFUSION". The record includes collaborations with well known local hip hop artists MC HotDog, MC Yan and Chef. Additional collaborations include Sammi Cheng and Jay Chou.

Fashion

Edison's foray into the fashion industry accompanied his rising success as a young pop icon. Edison, along with partners Kevin Poon and Billy Ip, became the founders of CLOT Inc., a clothing company described as a "lifestyle company" that is geared toward youth culture, and bringing street fashion to China and Hong Kong. The company has collaborated with many big clothing companies, such as Nike, A Bathing Ape, Subscrew and Disney. He is also part founder of clothing vendor JUICE, currently operating in Hong Kong (original), Shanghai and Kuala Lumpur with future plans to open a further 17 stores.

Multimedia company

In February, 2007, he invested $10 million HKD to open his own multi-media company, Clot Media Division, which plans to produce movies, commercials and music albums. In June, 2007, he released a Mandarin album, 讓我再次介紹我自己 (Allow Me To Reintroduce Myself) with tracks produced by Kanye West, Just Blaze and Clinton Sparks.

Community work

As early as 2001 Chen had appeared in Vancouver charity shows. He has also been a supporter for the gay and lesbian community in Hong Kong, including being voted as an icon in 2001.

In 2007 he was invited by Be@rbrick toys for a charity event in Hong Kong Harbour City. The charity proceeds were donated to "Hong Kong Blood Cancer Foundation".

Incidents

2004 Chen assault incident

In March, 2004, two male teenagers assaulted Chen in Central District of Hong Kong. The two teenagers mocked Chen with dance moves outside a record store. Immediately following the dance taunt, both of the teenagers punched Chen. Upon doing so the two teenagers fled the scene, and Chen gave chase. Chen eventually caught up to the two individuals as they were trying to board a bus. They were turned over to Hong Kong Police. As a result of the incident, Chen reported that he sprained his ankle and that his cheekbone and ear were also injured. Chen declined to press charges and the two individuals were released.

}}

2007 Taxi dent incident

Chen drove to his home after midnight 9 March 2007. The gate was blocked by a Toyota Crown Comfort taxi that had just dropped off its passengers. The taxi driver then signalled Chen to move away so he could pull out, clearing the way for Chen to enter. Chen's security guard told the taxi driver to pull over so that Chen could pass. The taxi-driver insulted the security guard. Chen proceeded to have an argument with the taxi driver. Despite the presence of the security guard and other witnesses, he got out of his car and kicked the taxi several times, denting it and breaking all its windows. He was subsequently charged by the police. On the basis of these charges he was convicted and placed on a one year good behaviour bond. He was also fined; the taxi company was granted HK$4,700 in compensation for the damage inflicted to the car.

2008 Photo scandal

In January 2008, Chen was involved in a widely publicized sex scandal when sexually explicit nude photographs of himself taken four years earlier became widely circulated on the Internet. Celebrities implicated in the scandal included Gillian Chung, Bobo Chan, Mandy Chen, Candice Chan, Rachel Ng and Cecilia Cheung. Nude photos of Edison's current girlfriend, Vincy Yeung, were also made public and the future of their relationship was the subject of intense media gossip.

Hong Kong police have stated that they confiscated a collection of sex-related photos that involve 6 other identifiable females and other unidentifiable males.

Initially the authenticity of the photos was denied, and digital manipulation was used as the primary explanation for the pictures. However, Hong Kong police and Photoshop experts argued that the photos were in fact real and not digitally altered. This brought about a serious reaction towards all parties involved in the scandal. As a result, Chen indirectly admitted his role and expressed remorse and subsequently announced his indefinite departure from the Hong Kong entertainment industry at a press conference.

Due to the scandal, the Google search engine rankings for 2008 resulted in Chen's Chinese name being the number 1 search term in China, and number 3 in Taiwan. Chen was runner-up to US president-elect Barack Obama in the Hong Kong Person of 2008 poll by government-run RTHK radio, with just under 30 percent of votes in the Person of the Year. On June 1, 2009, Chen spoke openly about the sex photo scandal for the first time since the scandal broke in an interview with TalkAsia on CNN. In the interview he reveals his side of the scandal and how he endured criticisms from the public, the media, and from the individuals affected by the case.

Personal

In Chen's personal blog, he referred to an anonymous girlfriend as "V". In 2007, he finally announced that he has been dating Vincy Yeung (the niece of EEG founder Albert Yeung) for 3 years. On an entertainment show in Taiwan, Chen disclosed that he planned to marry Vincy and that his previous playboy and womanizing habits have stopped because of his love for his current girlfriend. He repeated his gratitude to her in an interview with Time Out Hong Kong magazine in March 2011.

Gu Li (Chinese: 古力; Pinyin: Gǔ Lì; born February 3, 1982) is a Chinese professional Go player.

Biography

Gu Li is currently the #1 ranked Chinese player by the Zhongguo Qiyuan. He became a pro in 1994 when he was only 12. In 2006, he won the 10th LG Cup and became the youngest Chinese player to ever win a major international title; as a result, he was also promoted to 9 dan. In March 2007, he defeated Chang Hao 2-0 to win the Chunlan Cup. In mid 2007, Gu Li experienced a playing slump, even losing many matches against lower dan players. However, he soon came back stronger than ever, winning many major titles both domestic and international, including the 2007 Chang-ki Cup and the 2008 Fujitsu Cup; the greatest factors in this turnaround was his improvement in the endgame, and territory skills, which many people had previously considered his biggest weaknesses. In 2009 Gu defeated Lee Sedol to win the 13th LG Cup.

In July 2010, Gu Li became the "Meijin of Meijins" by defeating Lee Changho and Iyama Yuta in a special tournament which pitted the domestic title holders from China, Korea, and Japan against each other. In October 2010, Gu Li defeated Han Sang-hoon and Lee Sedol in the Round of Sixteen and Quarter-finals respectively to reach the semi-finals of the 15th Samsung Cup, whilst the defending Champion Kong Jie was knocked out by Kim Ji-seok. Gu won the 2010 Samsung Cup defeating Heo Yeong-ho of Korea, and moves on towards the 2012 Ing Cup to become the second player to win all Major International Titles (Although Lee Chang-ho is the first and so far only person to win all titles, including the defunct World Oza and Zhonghuan Cup, as well as the Tong Yang Cup).

Style

His given name Li, literally meaning strength, is also a Go term roughly meaning the ability of reading. Li also encompasses the meaning of the ability to discover strong moves and the ability to fight. Gu has a nickname called Gu Da Li. Da literally means large, big or huge. This refers to Gu's incredible ability at playing really strong moves that require sharp instinct as well as immaculate reading.

Titles & runners-up

Tied for second place in total number of Go titles won in China.
