A drum hoop clamp includes a pivotable clamp body supported on the drum beater as a pivot base for the clamp body and a clamping jaw rotatably journaled to the clamp body at one side of the clamp body pivot. When the clamp body pivots to move the clamp jaw against the drum hoop, the rotatable clamp jaw rotates with respect to the clamp body to an orientation providing fullest contact between the clamping surface of the clamp jaw and the drum hoop, regardless of the shape of the clampable surface of or the thickness of the drum hoop.
