Enhancing Skill for Playing Keyboard by Dynamics Modification

Abstract

Music timbre is changeing depending on keystroke position, rhythm, velocity and length when playing piano．Therefore it is not easy for beginners to learn how to press piano keys accurately and they also cannot easily use both hands at the same time when playing. Thus, it is necessary to practice for a long time to play the piano well. Currently, there are plenty of systems for enhancing playing skill. It is possible to provide more useful assist using haptic feedback when playing a musical instrument. In this paper, a skill evaluation method to play the keyboard is proposed. In order to improve the playing velocity skill, we compared the keystroke’s speed when playing the keyboard instrument and the tactile feedback to change the dynamics of the keyboard. Performance improvement on keystroke velocity using this reserch’s keyboard calibration is examined. Experiments were performed with and without calibration. Results demonstrate a better keystroke speed performance using the proposed calibration.
