Pattern grammars in formal representations of musical structures. 11th International Joint Conference on Artificial Intelligence, Workshop on AI & Music, 20 August 1989, pp.113-42
This paper introduces several formal models of pattern representation in music. Polyvalent multimodal grammars describe partially overlapping sound events as found in polyphonic structures. Bol Processor grammars are characterisations of sequential events in terms of substring repetitions, homomorphisms, etc. Parsing techniques, stochastic production and recent developments of BP grammars are briefly described.
