A study on the learning effect by the presented method of rhythm deviation in Japanese drums

Abstract

In this study, we have developed a rhythm deviation visualization system. The system shows player's rhythm deviation using colors during a performance. The colors show the direction and amount of the deviation. If player's rhythm is correct, the system shows white color. If player's rhythm is fast, the system shows red color. If player's rhythm is slow, the system shows blue color. The colors changes in accordance on the amount. As a result, improvement of skills rhythm was observed by recognizing their own rhythm.
