Abstract: A drum of the invention has a tubular drum shell, a replaceable annular bearing edge, a spline interconnecting the shell and the bearing edge, and a membrane overlaying the bearing edge. The bearing edge may have any of various profile configurations. The bearing edge overlays a shell edge in releasable engagement. A spline extends from the bearing edge and engages a recess, including an annular rabbet between the wall edge and an inside wall surface, or an annular void, including an annular slot dado, in the shell wall, releasably coupling the bearing edge and the shell. The shell may include an aperture through the wall. An air valve may be provided to regulate passage of air through the aperture between open and closed positions. The air valve may support an audio reception device. A portion of the inside wall surface may have an acoustic pattern that influences the drum's sound. The drum may also have a flangeless hoop or arcuate portions of the hoop without a flange.
