ABSTRACT:
An automatic accompaniment apparatus capable of automatically producing a bass tone by developing notes constituting a chord in the form of a broken chord in a predetermined order when keys constituting such chord are depressed. When a plurality of keys are depressed, there often exist a plurality of different chords constituted of notes corresponding to the depressed keys. The automatic accompaniment apparatus according to the invention is adapted to detect a single chord name among these plural chords in a certain predetermined order of preference and use the fundamental note and other notes constituting the detected chord as the bass accompaniment tone. The apparatus is capable of selectively restricting generation of notes other than the fundamental note which would normally be generated in the bass accompaniment using a predetermined note as the fundamental note, thereby providing bass variation effects to the generated bass tone.
The apparatus is also capable of performing a chord while producing a bass tone in the form of a broken chord of a selected chord by using a note corresponding to a single depressed key as the fundamental note and designating suitable notes as the notes other than the fundamental note constituting the chord.
Another example of the apparatus is disclosed in which a tone range within which the bass tone can be produced consists of plural octaves and the tone range can be adjusted in accordance with a kind of rhythm or chord.
