A classical acoustic guitar has six strings. There are variations in guitar configurations for creating different sounds, including the electric four-string bass guitar and the 12-string guitar that is played like a six-string but with two strings per note.
Stringed instruments create sound through the vibrations caused by the musician's manipulation of the strings. This is achieved through strumming, striking, plucking or rubbing a bow across the strings. The strings are supported by a bridge that transfers their vibrations into the top of the instrument, referred to as the sound board. The sound board carries the vibrations to the instrument's body, which is called the soundbox or resonator.
