Abstract

Every time a new chord signal is supplied to a chord memory circuit, a previous chord signal is supplied to a chord comparison and calculation circuit together with the new chord signal to obtain a chord change signal representing a degree of change between the two sequentially designated chords. The chord change signal is stored in chord change memory circuits. Chord name signals and chord change signals are compared with chord change pattern signals outputted from a change pattern memory to cause a coincidence signal to hold a latch. A rhythm pattern selection signal thus is supplied from the latch to a rhythm pattern memory circuit.
