Abstract
A drum is formed from a casing of wood, metal, plastic or the like which is of rectangular or other polygonal shape, which shape forms the wall of the drum. The ends of the casing are open, the one end having a circular or oval shaped frame extending therefrom over which a sheet of vellum is supported and stretched to form a percussion head. The opposite end of the casing is enclosed by spaced louvers which may be fixed in position or pivotedly supported for angular positioning within a frame. A baffle is provided within the casing which is operated to different angular positions from the bottom by a lever which extends through the casing at one side thereof.
