Proposal for Automated Creation of Drum´s Fill-In Pattern Using Interactive Genetic Algorithm

In recent years, the role of percussion instrument in music has become important. Especially, the drum is used in various genres such as brass band, jazz, and the pop music. The drum is one of the musical instruments, and becomes essential to music. In this work, we suggested automated creation of drum´s fill-in pattern using Interactive Genetic Algorithm (IGA). The proposed system created the drum´s fill-in patterns as individuals in GA, and the user evaluates them subjectively. Based on the fitness value, the proposed system performs GA calculation. As results of experiment 1 and 2, the average gradually increased in accordance with progress of generation. Especially, the significant increase of the fitness value was observed in the experiment 1. However, significant difference was not observed in the experiment 2.
