Hand drum hoop |
摘要 |
A drum hoop having an asymmetrical cross section for use in combination with hand drums. The drum hoop upper inner edge is connected to a lower inner edge having a larger diameter producing a drum hoop inner surface having an angular orientation to the central axis of the drum. The angular orientation of the inner surface maximizes clearance between the drum hoop and the variable diameter exterior surface of the drum shell. Added clearance allows a drum hoop constructed according to the invention to accommodate variations in exterior surface diameter often encountered in hand made drum shells common in the art.
