ABSTRACT:
A musical drum includes a generally spherical shell of a ceramic material having a thickness less than 3/8 of a inch as defining a resonant cavity therein; the shell having a bottom and an upper end; the shell being cut-out at the upper end thereof to define a first opening having a size sufficiently small to be entirely covered by the palm of a hand; the shell being cut-out, at a position between the first opening and a plane substantially mid-way between the bottom and the upper end, to define a second opening smaller than the first opening; and the shell being cut-out at a position below the plane to define a third opening for insertion of a microphone.
