Abstract
Recently, researches on interactive art regarding computer graphics and music are actively performed. In the computer music, genetic algorithm is usually used for the sound generation process, but it is difficult to handle these methods directly for the music composition. We propose a music composition system based on Twelve-tone Technique that is a composition technique of the contemporary music. Making of twelve-tone rows which is the first process of the Twelve-tone Technique is an important to determine the atmosphere of music. In this paper, we design the fitness function based on the relation that the consonance and dissonant interval that are a part of general musical theory and perform the automatic generation of twelve-tone row by searching the consonance tone row with GA. We confirmed the effectiveness of this system by constructing the simulator that generates twelve-tone rows and executing the comparison questionnaire of twelve-tone rows made by the simulator and human.
