New Techniques for Enhanced Quality of Computer Accompaniment
Roger B. Dannenberg, Hirofumi Mukaino · 1988
A computer accompaniment system has been extended with several techniques to solve problems associated with reliably recognizing and following a real-time performance. One technique is the use of an additional matcher to consider alternatives when the performance could be interpreted in two ways. Another is to delay corrective action when data from the matcher is suspect. Methods for handling grace notes, trills, and glissandi are also presented. The implementation of these and other techniques to produce an enhanced computer accompaniment system is discussed. 1. Introduction The basic technology for real-time computer accompaniment 1 of live musicians was first presented in 1984 [1, 2], however the first systems left a lot of room for improvement. We have been developing new computer accompaniment systems for two years in an effort to obtain higher reliability in the accompanist and also to deal with a more complete musical vocabulary. Like the first systems, the task is to accept a...
