Abstract
An automatic accompaniment circuit which is provided with a code detector for scanning key switches to detect the code of a depressed one of the key switches, a latch circuit for latching the output signal of the code detector by a bar clock pulse which is produced for each bar, a comparator for comparing the output signals of the code detector and the latch circuit to yield a coincidence signal, and control means for counting the coincidence signal from the comparator by a desired number of bars using the bar clock pulses and then providing a command signal for changing the pattern of an automatic accompaniment.
