Two-piano performance is a beautiful form of musical collaboration where two pianists create a dynamic dialogue by blending their unique styles. However, the performers' inability to see each other often leads to synchronization issues, requiring significant practice time. This study proposes “Piano Duo”, a practice support system for two-piano performances. By sharing sensory information through performance videos, core body movement sensing, and tactile feedback, the system aims to improve timing accuracy and practice efficiency. The results suggest not only enhanced synchronization and efficiency but also potential for more advanced artistic expression.
