Abstract
The purpose of the present study was to assess effects of daily piano practice on speed and accuracy. When they were asked to play the trained tone sequence as fast and accurately as possible, the maximum rate of keystrokes increased after the practice, indicating enhancement of finger movement speed. This was also the case when playing an untrained tone sequence with the left hand and untrained right hand as fast as possible. A retention test, being performed two months after the final practice session, revealed no apparent deterioration of the hand motor functions, suggesting robustness of motor memory acquired through the piano practice. Finally, provision of visual feedback regarding rhythmic accuracy of keystrokes facilitated the movement accuracy, which implicates a potential of the augmented feedback for improving piano performance.
