Shamisen players are conventionally play music without looking at a musical score in a concert. Likewise, some characteristic problems of Shamisen, such as frequently changing tempo of music and a distinctive style to write musical scores, make it harder to practice for memorization. In this research, we created an application that scrolls a musical score automatically in defined speed, and this makes it easier to play the Shamisen. There is a gap between defined speed and actual playing speed, the application searches the score and fixes score scrolling speed. After the implementation, we evaluated the performance of application. Although there is room for the improvement in accuracy of pitch detection of lower pitches, the system succeeded in score searching and scrolling the score along the actual performance. The result of the user study showed that this system is useful for practice.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告グループウェアとネットワークサービス（GN）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-03-06","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"69","bibliographicVolumeNumber":"2014-GN-91"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":99108,"updated":"2025-01-21T12:11:55.770043+00:00","links":{},"created":"2025-01-18T23:45:11.646756+00:00"}
