The guitar is a string instrument of the chordophone family constructed from wood and strung with either nylon or steel strings. The modern guitar was preceded by the lute, vihuela, four-course renaissance guitar and 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 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, folk, jazz, jota, mariachi, metal, punk, reggae, rock, soul, and many forms of pop.
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 guitarra moresca (Moorish guitar) and the guitarra latina (Latin 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. By the 14th century the qualifiers "moresca" and "latina" had been dropped and these two cordophones were usually simply referred to as guitars.
