ABSTRACT:
An automatic accompaniment apparatus performs an automatic accompaniment having much variety with less storing amount of information (e.g., rhythm pattern data or pattern data). Based on the stored information, generation of tone or chord is controlled. In addition, tie expression or shifting operation is also controlled. In the shifting operation, some of constituent tones constituting the chord are sequentially generated in a shifting manner. The tie expression is applied to the constituent tones which are commonly used between preceding chord and present chord.
