Multiple Representations of the UI, Score and Scale for Musical Performance System and Score DB

摘要

This paper describes the development and evaluation of the UIs and scores of musical performance system. The aim of this research is to provide a musical tool for elderly people and caregivers. Another aim of this research is to use the performance system and score database to conserve some non-Western music genres. The UIs are designed on a tablet PC, which look like keyboards. Four UIs with scores are evaluated by young people and elderly people: plain keyboard with staff notation score, and keyboards of note nameumber/color representation with scores of the same representation. The results of the experiment indicate that the number representation would be useful to most people and the note name/color representations would be useful to some people. This system also have a UI of koto music which is one genre of Japanese traditional music. This system can be used for the explanation of the difference between the temperament and scale of koto music and those of Western music. Scores for musical performance system and scores of koto music are also discussed. This research provides a system to add melody and rhythm using score DB to the lyric input by a user. This system can also explain the melisma of koto songs and asynchronicity of the rhythms of voice part and koto part.
