ABSTRACT:
A keyboard electronic musical instrument includes a plurality of playing keys, each of which are capable of coupling a set of chord tone signals to an output utilization circuit. These chord tone signals comprise the root and fifth parts and also the major third and minor third parts of a chord. Each of the playing keys are capable of operation to two different depressed positions, one of which causes the major third chord component to be supplied along with the root and fifth parts to the utilization device. The other depressed position of the key causes the minor third chord component to be supplied along with the root and fifth parts to the utilization device. Provision also is made for permitting only the root note tone signal to be passed to the output circuit to permit normal playing of the keyboard.
