A drum beater includes a support with the beater rotary shaft on the support. A swingable beater attached to the beater rotary shaft is adjustable in position around that shaft for establishing the swing distance between the beater and the drum head. An operating member on the shaft is connected to the drum pedal such that operation of the drum pedal rotates the shaft. A beater shaft restoring cam is attached to a spring which is increasingly tensioned as the drum pedal is operated and which returns the cam and the beater shaft to a return position when the pedal is released. The cam is adjustably positionable in orientation around the beater rotary shaft.
