Abstract
A system for interpreting the requests and performance of an instrumental soloist, stated in the parlance of the musician and within the context of a specific published edition of music the soloist is using, to control the performance of a digitized musical accompaniment. Sound events and their associated attributes are extracted from the soloist performance and are numerically encoded. The pitch, duration and event type of the encoded sound events are then compared to a desired sequence of the performance score to determine if a match exists between the soloist performance and the performance score. If a match exists between the soloist performance and the performance score, the system instructs a music synthesizer module to provide an audible accompaniment for the soloist. The system can provide an accompaniment for a selectable amount of time even if the soloist intentionally or unintentionally departs from the score.
