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. A point suspension
tension lug may secure the head to the shell.
