Piano Arrangement System Based On Composers' Arrangement Processes
Sho Onuma, Masatoshi Hamanaka · University of Michigan Library Repository · 2010
Our goal is to construct an automatic musical arrangement system by applying analysis results of composers’ arrangement processes. We arranged an orchestral score for a solo pianist to evaluate our system. Usually, an orchestral score has several instrumental parts, which is difficult for a soloist to play. Therefore, an orchestral score needs to be arranged with several instrumental parts into both hands parts, which enables a solo pianist to play with both hands. However, there is a problem with an arrangement of more than five notes for each hand, since one hand has only five fingers. To solve this problem, we introduce a protocol analysis for analyzing the process of arranging music. We applied this protocol analysis to a musical arrangement, and analyzed the arrangement process. By using the analysis results, we constructed a piano arrangement system for warning the composer of problems in the score that need to be arranged.
