ABSTRACT:
A computerized method and apparatus for providing a comparison between a performance and a performance score in order to provide coordinated accompaniment with the performance. The performance is converted into a performance related signal and is compared with a performance score. If a predetermined match exists between the performance and the performance score, accompaniment is provided. This is preferably accomplished on an event by event basis. Dynamic programming is preferably employed. The algorithm may be adapted to determine a match exists even though the performance departs from the performance score in respect of either content or timing up to a predetermined level.
