Interactive music composition system - composition of 16-bars musical work with a melody part and backing parts

This paper aims at the construction of a music composition system that generates 16-bars musical works by interaction between human and the system, using interactive genetic algorithm. The present system generates not only various kinds of melody parts but also various kinds of patterns of backing parts and tones of all parts, so that users can acquire satisfied musical work. The users choose generating mode of musical work from three points, i.e., melody part, tones of all parts, or patterns of backing parts, and the users evaluate impressions of presented candidates of musical work through the user interface. The present system generates the candidates based on user´s subjective evaluation. This paper shows evaluation experiments to confirm the usefulness of the present system.
