Until now, we examined the performance motion by the snare drum. Particularly, we analyzed an association between emotion and motion using motion capture. We analyzed total of six emotions [tenderness, happiness, sadness, fear, anger, and non-emotion from Juslin (2001)]. The analysis method averaged the performance motion of six emotions. We named the method as “Motion Averaging Method (MAM).” We calculated the difference of the each emotion by the MAM and revealed the characteristic of motion. From the result, we achieved results in snare drum motion. Therefore, in this study, we considered the association between emotion and motion in the keyboard. The subject was a professional pianist. A musical piece was an etude of the music dictation. Motion capture system is the MAC 3D System of Motion Analysis Corp., which is an optical motion capture system. The measurement marker bonded 33 points to the upper body. As a result, we understood the difference in emotional valence by the center of gravity of the head, an arm, the body, and the hand. Particularly, the non-emotion was move less than other five emotions. Then, we were able to express an association between five emotions of Juslin and motion as a figure.
