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 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== (詳細はchordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas.〔Wade, Graham. ''A Concise History of the Classic Guitar.'' Mel Publications, 2001.〕 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 Babylonia show people playing an instrument that has a strong resemblance to the guitar, indicating a possible Babylonian origin for the guitar.〔Dr. Michael Kasha, "A New Look at The History of the Classic Guitar", Guitar Review 30, August 1968, pp. 3-12.〕 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 ''ドイツ語:Gitarre,'' and the French ''フランス語:guitare'' were all adopted from the Spanish '','' which comes from the Andalusian Arabic '','' itself derived from the Latin ''ラテン語:cithara,'' which in turn came from the Ancient Greek ''.''〔''Kithara'' appears in the Bible four times (1 Cor. 14:7, Rev. 5:8, 14:2 and 15:2), and is usually translated into English as ''harp.'' Strong's Concordance Number: 2788 (BibleStudyTools.net )〕 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.〔Summerfield, Maurice J. (2003). ''The Classical Guitar, Its Evolution, Players and Personalities Since 1800'' (5th ed.) Blaydon on Tyne: Ashley Mark Publishing. ISBN 1-872639-46-1〕 At least two instruments called "guitars" were in use in Spain by 1200: the ''ラテン語:guitarra latina'' (Latin guitar) and the so-called ''ラテン語: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.〔(blog.reddogmusic.co.uk ), History of the Acoustic Guitar〕 By the 14th century the qualifiers "moresca" or "morisca" and "latina" had been dropped, and these two cordophones were simply referred to as guitars.〔Tom and Mary Anne Evans. ''Guitars: From the Renaissance to Rock.'' Paddington Press Ltd 1977 p.16〕 The Spanish vihuela, called in Italian the "ラテン語: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.〔"The first incontrovertible evidence of five-course instruments can be found in Miguel Fuenllana's ''Orphenica Lyre'' of 1554, which contains music for a ''vihuela de cinco ordenes.'' In the following year, Juan Bermudo wrote in his ''Declaracion de Instrumentos Musicales:'' 'We have seen a guitar in Spain with five courses of strings.' Bermudo later mentions in the same book that 'Guitars usually have four strings,' which implies that the five-course guitar was of comparatively recent origin, and still something of an oddity." Tom and Mary Anne Evans, ''Guitars: From the Renaissance to Rock.'' Paddington Press Ltd, 1977, p. 24.〕〔"We know from literary sources that the five course guitar was immensely popular in Spain in the early seventeenth century and was also widely played in France and Italy...Yet almost all the surviving guitars were built in Italy...This apparent disparity between the documentary and instrumental evidence can be explained by the fact that, in general, only the more expensively made guitars have been kept as collectors' pieces. During the early seventeenth century the guitar was an instrument of the people of Spain, but was widely played by the Italian aristocracy." Tom and Mary Anne Evans. ''Guitars: From the Renaissance to Rock.'' Paddington Press Ltd, 1977, p. 24.〕 In Portugal, the word ''viola'' referred to the guitar, as ''guitarra'' meant the "Portuguese guitar," a variety of cittern. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Guitar」の詳細全文を読む スポンサード リンク
