Claims (20)

1. Drum structure comprising, in combination

a) a drum shell and a drum head, and

b) a counter hoop to be supported by the shell proximate the head and having an edge shaped to resist or prevent drum stick damage,

c) there being a drainage gap or opening providing access between the counter hoop and its side wall, the gap or opening locating between the edge and said side wall, and

d) the edge being arcuate and rolled toward the outer side of the hoop.

2. The combination of claim 1 wherein the edge is blunted.

3. The combination of claim 1 wherein the edge is arcuate.

4. The combination of claim 1 wherein the gap or opening is at a terminal defined by the rolled edge, the gap or opening extending circularly about the drum axis along with the rolled edge.
