Abstract

It is said that music is effective for controlling feelings. For example, we can feel relaxed to listen to slow music. This paper proposes a generation system which composes music by means of a genetic algorithm. The composition which is generated by the system consists of the melody part, the chord part, and the bass part. The system can specify the atmosphere of the generated composition by choosing adjective words; "lightness", "intensity", and "complexity". To reflect the effect of adjective points on atmosphere of generated composition, the system adjusts the parameters of an evaluation function. As a result of a composition generating experiment, similar melodies and rhythms were found in each composition. To evaluate the appropriateness of the function about reflecting the effect of adjective points on atmosphere of generated composition, we conducted a questionnaire investigation. As a result, satisfactory answers are obtained for a specific adjective word.
