The guitar is a musical instrument with ancient roots that is used in a wide variety of musical styles. It typically has six strings.
Guitars are recognized as one of the primary instruments in blues, country, blues and the more popular rock and roll. They can also be a solo classical instrument.. Guitars may be played acoustically, where the tone is produced by vibration of the strings and modulated by the hollow body, or they may rely on an amplifier that can electronically manipulate tone. The electric guitar were introduced in the 20
th century and continue to have a profound influence on popular culture.
Traditionally guitars have usually been constructed of combinations of various woods and strung with animal gut, or more recently, with either nylon or steel strings.
