| Research Abstract |
Recently, many piano schools have introduced "piano duo performances" in piano lessons for children. It have been found that pupils have been motivated to practice piano by this method and that they could learn ensemble with partners. However, it is still difficult for children to play a piano duo at home with their family members who have little experience in piano performances. Accordingly, we created "Family Ensemble," a piano duo support system for a musically inept parent and his/her child who is a beginner at playing the piano. The system makes it easier for parents to correctly reproduce a given sequence of pitches along with the child's performance by using score tracking and note-replacement functions. The experiments with this support system showed that the parents can immediately participate in the piano duo. Furthermore, we found that during joint practices using Family Ensemble some subjects discussed musical ideas that they would not have talked about without using the system. Furthermore, as an expansion of Family Ensemble, we developed an computer-aided instruction system of piano performances that indicates some model performances in audio and video when the system finds an unexpected pause in a performance. If some mistakes included in a phrase just before the pause, this system shows a model performance of the phrase. If no mistakes are found, the system shows a model performance of a phrase just after the pause. In addition, we analyzed constructing processes of musical expression focusing on key-release actions and we developed a voice-to-MIDI interpreter that allows users to input digital musical performance data by singing in any style (even sing with lyrics) with concurrently inputting rhythm tapping data. Thus, in this research, we established basic technologies for totally supporting novices' practices of musical performances.
