Composition of music using human evaluation
Muneyuki Unehara, Takehisa Onisawa · 2002
This paper describes an interactive music composition system that uses interactive genetic algorithms (GAs) and music theory. One piece of music consisting of four bars corresponds to one chromosome containing information on the melody part and the backing parts. The music is composed using GA operations. A user listens to the presented music and evaluates whether it fits his/her feeling. The user evaluations have an influence on the GA operations. Experiments are carried out in order to confirm the usefulness of the system. From the results of these experiments, it is found that the subject's evaluation becomes higher as the number of generations increases. This means that the system composes music works reflecting the user's feeling of music.
