Abstract: | This paper aims at constructing a music composition system that composes music by the interaction between human and a computer.
Even users without special musical knowledge can compose 16-bar musical works with one melody part and some backing parts
using this system. The interactive Genetic Algorithm is introduced to music composition so that users’ feeling toward music
is reflected in the composed music. One chromosome corresponds to 4-bar musical work information. Users participate in music
composition by evaluating composed works after GA operators such as crossover, mutation, virus infection are applied to chromosomes
based on the evaluation results. From the experimental results, it is found that the users’ evaluation values become high
over the progress of generations. That is, the system can compose 16-bar musical works reflecting users’ feeling.
