Guitar (Italian: Chitarra), also translated as guitar or six-stringed piano. A plucked instrument, usually with six strings, similar in shape to a violin. The guitar is often seen as the main instrument in pop, rock, blues, folk, and flamenco. In the field of classical music, the guitar is often performed as a solo or duet; of course, in chamber music and orchestral music, the guitar also plays a considerable role as a foil. Classical guitar, violin and piano are listed as the world's three most famous musical instruments. As a member of the stringed instrument family, the guitar is a stringed playing instrument that produces sound by plucking the upper strings. When playing, pluck the strings with one hand, while the fingers of the other hand rest on the fretboard, which is the metal strip that covers the neck. The resulting sound is enhanced by the guitar's soundbox. There are four main ways to play the guitar: one is to play with your fingers, but the nails are easily damaged, so people often use fake nails or put on the nails that can strengthen the nails; The box emits music. The third is to play with a metal round pipe (slide guitar, Slide Guitar). The fourth, less popular, is to use a finger cot that can be worn on the fingers to play.
