Abstract
A hand-held percussion device which can make different sounds when shaken, struck, or scraped is now available. The device comprises a frame that is made of two sound boards interconnected and separated by a top block on one end and joined on the other end. Between the top and bottom of the device, a bridge interconnects and separates the sound boards thereby determining their length and tension. The bridge also creates at least two separated sound chambers in the frame. A top plate is placed over the upper side of the sound boards and a lower plate is placed over the bottom side of the sound boards. The top plate and bottom plate, respectively, can be separated from the sound boards by use of spacers. Filler materials such as 'BBs' or other bead-like materials can be placed within one or more of the chambers thereby allowing the device to make noise when vibrated. Tone prongs are placed in one or more of the chambers thereby creating an entirely different sound when the filler material strikes against the tone prongs and sound boards, or plates. The device is shaped in such a way as to make it easily hand-held.
