Abstract
A drumhead having a tone control ring which suppresses unwanted overtones while preserving the desirable fundamental tones. The tone control ring has its outside edge fixed to the drumhead hoop and extends along the inwardly facing surface of the drumhead sheet with its inside edge free to move and located inwardly of the bearing area of the drumhead. Small vent openings may be provided in the peripheral area or some other vibrational area of the drumhead to accelerate the decay of vibrations for further muffling of overtones. In an embodiment of the invention applicable to bass drums, the batterhead of the base drum is provided with an imperforate annular flap interposed loosely between the control ring and the drumhead for additional overtone suppression.
