Toward a formal study of jazz chord sequences generated by Steedman?s grammar

M. Chemillier
2004 Soft Computing - A Fusion of Foundations, Methodologies and Applications  
This paper shows how to generate jazz chord sequences incrementally using Steedman's grammar by taking advantage of some formal properties.  ...  By precompiling them, one could improve the implementation of Steedman's grammar in a real-time system for improvisation, and make it more reactive to the inputs of the user.  ...  Besides the improvisation itself (the musician plays phrases which are recorded by the system, and transformed into new phrases in the same style, according to a model introduced in [1]), the system provides  ...
