Double bass

The musician, or double-bassist, may either play it while seated or standing. When standing, the bass is supported by the left leg while the left hand moves up and down the fingerboard. When seated, the bass is supported by the musician's right thigh and pelvis and by the use of an endpin on the floor. The double-bass is played by using a bow across the strings (especially in symphonic music), striking or plucking (especially in jazz) the strings.
