Abstract
A variable pitch percussion instrument comprising a drum body having an open end with an annular edge, and at least one drumhead assembly, including, flexible drumhead material stretched across the open end and an annular drumhead mounting ring secured to the perimetrical edges of the flexible drumhead so that tension can be increased on the drumhead by pressure between the open end of the drum body and the head. A plurality of flexible linear connecting elements, each having a pair of ends has one end of each of the flexible linear elements circumferentially around the mounting ring and the other ends, respectively, the other end of the drum body. A flexible tuning element located between the ends of the connecting elements, respectively, and arranged to tangentially engage and circumferentially wrap around the connecting elements such that when the area enclosed by the flexible tuning element is varied it causes the connecting elements to apply more or less tension on the drumhead material and change the pitch when the drumhead is vibrated. The drum body is mounted on a floor stand and a foot pedal mechanism is included to actuate the tuning element.
