Abstract
A percussion instrument includes a sound chamber having a cavity therein with at least one opening thereinto, support means secured to the chamber within the cavity, a resilient, elongated member disposed within the cavity of the chamber, one end of which is free-standing and the other end of which is coupled to the support means, a knocker secured to the free end of the resilient member, and a vibratory, elongated rod which is secured to the sound chamber. The rod includes a handgrip along one portion of its length for imparting sustained vibrations to the resilient member and, in turn, the knocker, so that the knocker will strike the walls of the sound chamber to thereby produce a percussion sound. The instrument is particularly suitable for simulating the sound of a jawbone percussion instrument, used for Latin American music.
