ABSTRACT:
An automatic accompaniment instrument detects a change in a chord progression formed of a sequence of chords. A pitch of an accompaniment tone to be reproduced is controlled based on a present chord and/or an immediately following chord of the chord progression, as well as on a pitch of an accompaniment tone generated on an immediately preceding occasion, when a change in the chord progression is detected.
