In recent years, genetic algorithm (GA) and interactive genetic algorithm (IGA) are usually used for the sound generation process in the field of computer music. However, it is difficult to just handle these methods directly for the music composition. In this research we have already proposed a music composition system based on the Twelve-tone Technique which uses twelve notes of the chromatic scale equally and composes the music step by step. We have designed the fitness function based on the relation between the consonant interval and dissonant interval that are a part of general musical theory and performed the automatic generation of twelve-tone row by searching the consonant tone row with GA. In the next step, we design a fitness function for evaluating the rhythm that we defined. In this paper, we propose an automatic rhythm generation method and try to obtain the musical rhythm using GA.
