A Technique for Regular Expression Style Searching in Polyphonic Music.

Abstract

This paper discussed some of the ongoing investigative work on integrating these two systems conducted as part of the NSF/JISC funded OMRAS (Online Music Retrieval and Searching) project into polyphonic searching of music. It describes a simple and efficient “piano-roll” based algorithm for locating a polyphonic query within a large polyphonic text. It then describes ways in which this algorithm can be modified without affecting the performance to allow more freedom in the how a match is made, allowing queries which involve something akin to polyphonic regular expressions to be located in the text.
