Abstract
This paper shows a system which semi-automatically arranges an orchestra score for a duo score. To arrange an orchestra score for a duo score, we need to divide an orchestra score into solo and piano accompaniment score. However, it is too difficult to arrange an orchestra score for piano score. An orchestra score consists of several instrumental parts, therefore it needs to be arranged for piano accompaniment to play. This system arranges considered problems for playing piano and generates a piano accompaniment score. It combines a piano accompaniment score with solo part score manually extracted in advance, it generates a duo score.
