Abstract
The present invention is a system for modifying the tonal output of a hand drum. The system includes the use of a tonal cover or membrane to change the sound emitted when the head of a hand drum is struck. Additional tuning pads are then added to further modify the sound of the drum. Tonal adjustment is affected by the number, thickness, material and tautness of the additional pads and tonal cover. A partial coverage of the drum head by a tonal cover may also be utilized.
