Guitar
The guitar is a popular musical instrument classified as a string instrumentwith 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 fret) the strings with 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-courseRenaissance 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' 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 fingerpickingtechnique. The term fingerpicking can also refer to a specific tradition of folk, blues, bluegrass, and country guitar playing in the US.
Electric guitars, introduced in the 1930s, use an amplifier that can electronically manipulate and shape the tone. Early amplified guitars employed a hollow body, but a solid body was eventually found more suitable, as it was less prone to feedback. Electric guitars have had a continuing profound influence on popular culture.
The guitar is used in a wide variety of musical genres worldwide. It is recognized as a primary instrument in genres such as blues, bluegrass,country, flamenco, folk, jazz, jota, mariachi, metal, punk, 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".[1] The term is used to refer to a number of chordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas.[2] A 3,300-year-old stone carving of a Hittite bard playing a stringed instrument is the oldest iconographic representation of a chordophone and clay plaques from Babyloniashow people playing an instrument that has a strong resemblance to the guitar, indicating a possible Babylonian origin for the guitar.[3][4]
The modern word guitar, and its antecedents, has been applied to a wide variety of chordophones since classical times and as such causes confusion. The English word guitar, the German Gitarre, and the French guitare were adopted from the Spanish guitarra, which comes from the Andalusian Arabic قيثارة qitara,[5] itself derived from the Latin[citation needed] cithara, which in turn came from the Ancient Greek κιθάρα kithara.[A]
The term guitar is descended from the Latin word cithara but the modern guitar itself is generally not believed to have descended from the Roman instrument. Many influences are cited as antecedents to the modern guitar. Although the development of the earliest "guitars" is lost in the history of medieval Spain, two instruments are commonly cited as their most influential predecessors, the European lute and its cousin, the four-string oud; the latter was brought to Iberia by the Moors in the 8th century.[6]
At least two instruments called "guitars" were in use in Spain by 1200: the guitarra latina (Latin guitar) and the so-called guitarra moresca (Moorish guitar). The guitarra moresca had a rounded back, wide fingerboard, and several sound holes. The guitarra Latina had a single sound hole and a narrower neck.[7] By the 14th century the qualifiers "moresca" or "morisca" and "latina" had been dropped and these two cordophones were simply referred to as guitars.[8]
The Spanish vihuela or (in Italian) "viola da mano", a guitar-like instrument of the 15th and 16th centuries, is widely considered to have been the single most important influence in the development of the baroque 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 16th 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 relatively 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.[B][C] In Portugal, the wordviola referred to the guitar, as guitarra meant the "Portuguese guitar", a variety of cittern
Types
Guitars can be divided into two broad categories, acoustic and electric:
Acoustic guitars
Acoustic guitars form 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.
Electric guitars
Electric guitars can have solid, semi-hollow, or hollow bodies; solid bodies produce little sound without amplification. Electromagnetic pickups convert the vibration of the steel strings into signals, which are fed to an amplifier through a patch cable or radio transmitter. The sound is frequently modified by other electronic devices (effects units) or the naturaldistortion of valves (vacuum tubes) or the pre-amp in the amplifier. There are two main types of magnetic pickups, single- and double-coil (or humbucker), each of which can be passiveor 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.[citation needed] Solid body seven-strings were popularized in the 1980s and 1990s in part due to the release of theIbanez Universe guitar,[citation needed] endorsed by Steve Vai. Other artists go a step further, by using an eight-string guitarwith two extra low strings. Although the most common seven-string has a low B string, Roger McGuinn (of The Byrds andRickenbacker) 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.[citation needed]
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,[13] 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.[14]
