Abstract: THEMES is a computer program which may be used to prepare models of musical structures. The program searc~es for recurring musical patterns, identifies such patterns and fits them into a structural description of the composition. In general there are a very large number of different descriptions of a composition in terms of sets of repeated note sequences. The goal is to identify a model which a person knowledgeable in the art of composition might call a "good" model. To arrive at such. a model it is necessary to order the search with regards to the overall structure of the music at hand. A two-pass search strategy is defined. The first pass, by applying a simple equivalence relation to the composition, gives the necessary general picture of the musical structure which defines how the detailed search and identification of the second pass will be ordered.

Descriptive terms: musical analysis, heuristic search, EUTERPE
