Musicians have to coordinate movements interpersonally to perform in an ensemble. As such, this study explores how violinists coordinate movements to play the same melody together in terms of the leader–follower relationships revealed by players’ movements. Twelve violinists participated in the study and played a violin ensemble in pairs. We applied Granger causality analysis to the three-dimensional displacement data of players’ heads, violins, and bows to identify leader–follower relationships between players. The results revealed the following: i) the participants adopted leader–follower roles during trials; ii) as the performance proceeded, the participants swapped roles; iii) the more difficult the parts of the score, the more notable the leader–follower relationships; iv) compared with between-head and between-violin data, the movements for between-bow data were more similar in more parts of the score that demonstrated leader–follower relationships. Further examination of cases where the leader–follower relationships were identified showed that players may have employed their own strategies to achieve a stable, coordinated state. These results suggest that, when the roles of players are not fixed in violin ensembles, performance can be adjusted in multiple ways, including swapping leader–follower roles, which is in stark contrast to previous studies that reported fixed leader–follower relationship when the first violinist only led the other parts in a string quartet.

In drum-set playing,drummers need to maintain accurate and powerful performance.What kind of postural control makes it possible to achieve this? The present study investigated the differences in postural control between expert (N=3) and novice (N = 4) drum-set players.Participants in this study performed an 8-beat rhythm pattern using an electric drum set consisted of hi-hat cymbals,a snare drum,and a bass drum.Tap-pressure data of each instrument and center-of-pressure (CoP) data of the participant were recorded and analyzed. As indices of performance accuracy and intensity,mean and standard deviation (SD) of inter-tap interval (ITI) and mean and coefficient of variation peak tap force applied to each instrument were calculated from the tap-pressure data.A principal component analysis was performed to compute the area of CoP and the circular SD of the principal component angle.The area of CoP and the circular SD were used to evaluate the magnitude of movement and the variance in movement direction, respectively. We found the followings: As for the experts,the SD of ITI and circular SD were small and consistent across the individuals,while the individual differences was relatively large in the peak tap force and area of CoP.The SD of ITI and circular SD of the novices were comparable to those of the experts.The individual differences in the drum-set playing skills seemed to be dependent on musical background of the individuals.
