In recent years, MIDI data has been used mainly in piano education. However, MIDI data does not contain information on the player's hand movements. Therefore, the purpose of this study was to clarify the movements required for more skillful performance by using a measurement system with inertial sensors that have fewer spatial constraints. In this study, tremolo, a piano playing technique in which two notes separated by the little finger and thumb are quickly repeated alternately, was taken up as a measurement movement, and the movements of three subjects were measured and their skills were evaluated. As a result of breaking down the tremolo into cycles, the number of cycles per second tended to be larger for subjects with longer piano experience. It was found that in order to perform the tremolo required to play a piece of music, it is important to minimize finger movements and use mainly the elbow and shoulder joints, and that synchronized internal and external rotation of the shoulders and flexion and extension of the elbows enable faster tremolo performance.
