  • Measurement of the motion during playing tremolo on mandolin

抄録

<p>The objective of this study is to measure the hand motion during tremolo playing on mandolin and evaluate how the movements vary based on skill level and playing style. The test subjects consisted five mandolin players with varying years of experience. Hand motions were measured using an inertial sensor placed on the back of the right hand, which held a pick. Subjects played tremolo on each of the four strings in five styles: neutral, fast, slow, forte, and piano. The targeted parameters were the angular velocities around the distal and dorsal axes. The phase lag between these axes was considered as the characteristic of the motion. Each angular velocity was bandwidth filtered and time-integrated, and the ratio of the ranges of each axis was also considered as a characteristic. As a result, the variation of the motions became larger for different styles of the tremolo by being skilled, while individual differences decreased. It was suggested that as skills improve, individual differences decreased due to approaching an ideal motion, and players developed expressiveness through variations in their motion. However, due to the limited number of test subjects, it remains unclear whether these findings represent a general characteristic.</p>
