A tempo setting device for use in an automatic rhythm instrument comprising a control means actuatable repetitively by the instrument player to produce a plurality of signals at a rate corresponding to a desired tempo and a circuit means responsive to the signals to produce a control signal related in magnitude to the rate. The control signal is applied to a voltage controlled tempo oscillator which is part of the automatic rhythm instrument and has an output frequency determined by the magnitude of its input signal. Thus, by actuating the control means at a rate corresponding to the desired tempo, the instrument player can regulate the tempo of the automatic rhythm instrument.
