Abstract
The present invention comprises a drum with two playing surfaces on opposites ends of a hollow drum body. The drum is configured for the first drum head to produce a loud sound and the second head to produce a quiet sound, under the same full force drum strikes without compromising the feel and rebound of the drum heads. The drum may have a central base, a shell disposed on each side of the base, and a drum head stretched over each of the shell. The drum heads are attached to a shallow drum body with independent tensioning of the heads and sandwiched drum shells. The tensioning system is mounted to the central base. An optional snare system may be mounted to the base.
