This paper presents a design of support system for music composition based on Simulated Breeding, a type of interactive optimization technique of Evolu- tionary Computing. In our prototype system named Sbeat, each individual in the population is a short mu- sic section of sixteen beats including three parts, gui- tar, bass, and drums. The melody and rhythm are gen- erated by a type of recursive algorithm from genetic information. By selecting favorite piece among scores displayed on the screen, the user listens to the sounds and decides which should be the parents to reproduce offspring in the next generation. Embedding some do- main specific functions, we can build a useful tool to make it easier for a beginner to compose his/her fa- vorite music pieces.
