“…Dalmazzo, et al (2019) attempted to classify the bowing motions with different playing styles, such as detache, staccato, or spiccato, using inertial and audio information, and showed that the motions were appropriately classified by the inertial sensor information. In a later study by Dalmazzo, et al (2020), the number of subjects was expanded to nine with different levels of proficiency, and the accuracy of classification based on inertial sensor data was evaluated. The movements in these studies were repetitive reciprocating motions similar to tremolo, even with a longer period, suggesting that inertial sensor measurements may be valid for mandolin tremolo as well.…”

Tremolo is a technique to produce the same note continuously in short spans, and is an important technique for musical performance on a mandolin. However, it is not easy for beginners to master this technique, nor is it easy for even expert players to perform a wide range of expressions. There is no unified view on the proper behavior of tremolo playing, and there are no examples of measured tremolo behavior. In this study, we measured the hand movements during tremolo playing on a mandolin. One test subject was included in this study. An inertial sensor was attached to the back of the hand, and the movement was evaluated by the angles which were the time integrated angular velocity on each axis. Tremolo playing is a combination of elbow and wrist motion. We examined how those motions were used for playing strong/weak tones or fast/slow tremolos. The results showed that there was a clear difference in motion between tremolo using the wrist and tremolo using the elbow. The results also suggested that the combination of each joint motion was changed when adjusting the volume and tremolo speed. It indicated that the measurement of hand movements by inertial sensors could be used to evaluate tremolo playing. Our future plan includes a more detailed analysis of the relationship between musical expression and tremolo movement, and an examination of how movement changes with practice.
