Pedal steel guitar

The pedal steel guitar is a type of electric steel guitar that is built on legs or a stand and is fitted with foot pedals and knee levers which adjust the sound of the instrument. Like other electric guitars, the musical instrument produces sound by the vibration of its strings which are converted by magnetic pickup connected to an amplifier.

Pedal steels may have one or two "necks" that typically have 10 strings each, but may have as many as 14. Unlike most other guitars, pedal steel guitars have reference lines on the fretboard where frets would be, but no actual frets. The player changes the pitch of one or more strings by sliding a metal bar (a steel) from one position to another while plucking the strings with the other hand, or vibrating them with a mechanical device. Pedal steels are typically plucked with a thumb pick and fingers, or two or three fingerpicks.

The distinctive feature of pedal steel guitars are the namesake pedals as well as knee levers which affect the pitch of the instrument. The pedals are mounted on a cross bar below the body and the knee levers extend from the bottom of the guitar's body and stretch or slacken the strings to change pitch as the guitar is played. The action of the pedals may be fixed or may be configurable by the player to select which strings the pedals affect. While there are some fairly standard pedal assignments, many advanced players devise their own setups, called copedents. The range of copedents that can be set up varies considerably from guitar to guitar. Aftermarket modifications to make additional copedents possible are common.

Steel guitar

Steel guitar is a type of guitar or the method of playing the instrument. Developed in Hawaii in the late 19th and early 20th centuries, a steel guitar is usually positioned horizontally; strings are plucked with one hand, while the other hand changes the pitch of one or more strings with the use of a bar or slide called a steel (generally made of metal, but also of glass or other materials). The earliest use of an electrified steel guitar was first made in the early 1930s by Bob Dunn of Milton Brown and His Brownies, the original Western Swing Band from Fort Worth, Texas; the instrument was perfected in the mid to late 1930s by Fort Worth's Leon McAluff, who played for Western Swing's greatest band ever, Bob Wills and His Texas Playboys. Nashville later picked up the use of the steel guitar in the early days of the late 1940s and early 1950s "Honky Tonk" country & western music with a number of fine steel guitarists backing names like Hank Williams, Lefty Frizell and Webb Pierce. The term steel guitar is often mistakenly used to describe any metal body resophonic guitar.

Guitar

The guitar is a popular musical instrument classified as a string instrument with anywhere from 4 to 18 strings, usually having 6. The sound is projected either acoustically or through electrical amplification (for an acoustic guitar or an electric guitar, respectively). It is typically played by strumming or plucking the strings with the right hand while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument.

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 strings's vibration, 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 finger-picking technique. The term "finger-picking" can also refer to a specific tradition of folk, blues, bluegrass, and country guitar playing in the United States.

Pedal

A pedal (from the Latin pes, pedis, meaning 'foot') is a lever activated by one's foot, sometimes called a "foot pedal" (but all pedals are used by a foot). It may specifically refer to:

Steel

Steels are alloys of iron and other elements, primarily carbon, widely used in construction and other applications because of their high tensile strengths and low costs. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the crystal lattices of iron atoms.

The carbon in typical steel alloys may contribute up to 2.1% of its weight. Varying the amount of alloying elements, their formation in the steel either as solute elements, or as precipitated phases, retards the movement of those dislocations that make iron comparatively ductile and weak, and thus controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel's strength compared to pure iron is only possible at the expense of ductility, of which iron has an excess.

Although steel had been produced in bloomery furnaces for thousands of years, steel's use expanded extensively after more efficient production methods were devised in the 17th century for blister steel and then crucible steel. With the invention of the Bessemer process in the mid-19th century, a new era of mass-produced steel began. This was followed by Siemens-Martin process and then Gilchrist-Thomas process that refined the quality of steel. With their introductions, mild steel replaced wrought iron.
