Abstract
An automatic musical instrument in which a chord discrimination and a musical performance circuit are arranged so that a comparator with multiple input terminals on one side, is connected to a memory circuit having multiple basic types of chords memorized. The comparator has multiple input terminals on the other side connected to key switches through a shift register. The comparator, furthermore, has a control electrode connected to a clock pulse generator which is connected, in turn, to multiple input terminals of the memory circuit, by way of two counter circuits. The latter have multiple output terminals connected, respectively, to two latch circuits. The comparator has an output terminal connected to control electrodes of the latch circuits. The musical performance circuit has a decoder connected to multiple output terminals of one of the latch circuits.
