Abstract
A musical drum includes a hollow cylindrical shell; a drumhead tightly stretched over and sealing each end of the shell, so as to form a resonance chamber between the drumheads and the shell; and two counterhoops fixed around the two drumheads to hold them on the shell. The shell is provided on at least one end with a flat contact surface for horizontally contacting with the drumhead. The flat contact surface has a radially outer edge forming a curved surface downward extended to an outer circumferential surface of the shell, and a radially inner edge forming a bevel downward extended to an inner circumferential surface of the shell. With the flat contact surface and the curved surface, the drumheads can be more tightly attached to the shell, allowing the vibration of the drumheads to be efficiently transmitted to the shell to produce more saturated resonant frequency and good sound sustainability.
