Make Me a Match: An Evaluation of Different Approaches to Score—Performance Matching
Hank Heijink, Peter Desain, Henkjan Honing, W. Luke Windsor · Computer Music Journal · 2000
A matcher is an algorithm that links events in a musical performance to the corresponding events in a score. Matching is difficult because performers make errors, performers use expressive timing, and scores are frequently underspecified. In this article, two existing matchers are discussed. A general control structrure is described, in order to respecify these matchers and to be able to compare them. A new matcher is proposed that uses structural annotations in the score to deal better with the difficulties in matching.
