Claims

[Scope of utility model registration request]

a tempo adjustment operator; a variable tempo oscillator that generates a tempo clock signal having a frequency according to the setting state of the tempo adjustment operator; and a sequential pulse generator that counts the tempo clock signal and repeatedly generates pulses in sequence. a pulse combination circuit that sends out a series of timing pulses by combining the sequential pulses in different ways depending on the setting state of the tempo adjustment operator; a counter that counts the series of timing pulses; and a counter for counting the series of timing pulses. An automatic rhythm performance device comprising a percussion instrument sound generating means for generating a percussion instrument sound signal according to the rhythm pattern by reading out a predetermined rhythm pattern according to the output.
