Abstract:
Reduction is a method for arranging the scores of a multipart composition to its ensemble. In this study, we propose an arrangement system using the full score to automate the arrangement by reduction. Our target instrument for this study is an electronic organ, which has a score similar to the score of an ensemble. First, we performed clustering based on the rhythm, melodic activity, harmony, sonic richness, and timbre of the instruments to reduce the part number of the melody in the full score. Further, we selected clusters of melodies corresponding to the right-hand, left-hand, and foot parts of the electronic organ. Finally, the musical score was rectified to be able to play the electronic organ. This system was evaluated using four songs. The average values of the right-hand, left-hand, and foot parts were 0.80, 0.71, and 0.77, respectively. These results depicted that the proposed arrangement was suitable for preparing electronic organ scores from the full score.
