Abstract of the Disclosure A percussion instrument includes a drum body and a percussion head movable with respect to and stretched over the drum body. A master tensioning member is provided for pulling the drumhead downward to enable a musician to vary the pitch of the sound produced when the drumhead is struck. The master tensioning member is operatively coupled to the drumhead, and is adaptable for use with drumheads of varying size. A lever system is provided for moving the master tensioning member vertically downwardly. A foot pedal is provided for enabling the user to actuate the lever system. The pedal includes an engaging tooth, and is swivelable to engage and disengage the tooth with complementary teeth to lock the pedal selectively in position. The pedal tooth thereby permits the user to adjust and fix the tension on the drumhead. The pedal is connected to the lever system by a movable fulcrum, which permits the user to exert a smooth, even force when depressing the pedal and actuating the lever system.
