【 摘 要 】

References(8)In order to realize musical performances with human-like emotions by computer, it is necessary to analyze performances using musical score data. The Dynamic Programming (DP) method is often used for matching between a musical score and its performance. However, the DP does not achieve a high matching rate since the ordering of attack of the notes in a chord is not always the same and there are difficult passages of right and left hand performances. Furthermore the score does not define the number of iterations of trills. This paper addresses the process of matching two or more MIDI performance data involving DP along with linear interpolation to maximize the collation between the score and the performance. The improved DP method is also extended to match performances including trills.
