Abstract

This paper describes the construction of the system which generates variations on a theme music fitting to story scenes represented by texts and/or pictures. Inputs to the present system are an original theme music and numerical information on given story scenes. The present system varies (1) melodies, (2) tempos, (3) tones, (4) tonalities, and (5) accompaniments of given theme music based on impressions of story scenes. Genetic algorithms using neural network models as fitness functions are applied to the music generation in order to reflect user's feelings on music and stories. This paper also describes the evaluation experiments to confirm whether the generated variations on a theme music reflect impressions of generated story scenes appropriately or not.
