ABSTRACT:
An electronic organ provided with a selector for selecting a three-finger chord playing mode or a one-finger chord playing mode. When the three-finger chord playing mode is selected, a chord is sounded by three or four fingers on a manual keyboard or lower keyboard as in the conventional electronic organ. On the other hand, when the one-finger chord playing mode is selected, there can be automatically sounded one of chord types, such as major, minor, seventh and minor seventh chords, which have, as the root note, the note of a key being actuated on the manual keyboard. The selection of a chord type is effected by a pedal keyboard.
