1. A percussion drum, comprising:
a plurality of vertical staves, each vertical stave having top, bottom, left and right edges and inner and outer surfaces, wherein each of said left edges defines a left edge profile and each of said right edges defines a right edge profile, wherein the shape of the left edge profile of each vertical stave cooperates with the shape of the right edge profile of a next adjacent vertical stave to form stave joints which mechanically interlock the staves such that the stave joints allow the staves to slide vertically relative to each other while preventing the staves from separating from each other in the horizontal direction, wherein said mechanically interlocked adjacent staves form a vertical cylinder having a top cylinder edge and a bottom cylinder edge; and further comprising a top drum head and upper hoop mounted on the top cylinder edge, said top drum head including a thin sheet material which vibrates when hit to make a drum sound. |
