Abstract
Embodiments of the present invention comprise an electronic system by which it is possible to have an accompaniment that automatically tracks the performance tempo of a performer. The system is equipped with a ROM in which a sequence of performance data that comprise a main performance composition that is to be performed by the performer is stored. The system receives input from the performer, for example, keystrokes of a keyboard, and the relative performance tempo of the performance by the performer is calculated with respect to a segment of the performance. An accompaniment is then generated by the system by comparing the detected tempo of the performance of the artist with the tempo of the reference performance that is stored in ROM. By knowing the difference in tempo between the reference piece stored in ROM and the piece as being performed by the performer, the system may then adjust the tempo of the accompaniment to match the tempo of the performance by the artist.
