Abstract
A new automatic accompaniment apparatus for sequentially reading out at a predetermined tempo accompaniment pattern information, including interval shift information, stored in a pattern memory and then generating tones of a designated chord, designated by a chord designatin means such as a keyboard, based on the accompaniment pattern information, thereby performing an accompaniment performance. The new automatic accompaniment apparatus, when the interval shift information is read out, will play a chord which is constituted by shifting intervals of part or all of the constituting tones of the designated chord in place of the designated chord, thus enabling an accompaniment performance rich in variety to be played as compared with a conventional apparatus having a memory capacity equivalent to that of the present accompaniment apparatus.
