Generating and Displaying the Human Piano Performance

摘要

The piano performance is realized by the dynamic hand and finger movements, which are constrained due to the anatomical components, such as tendons and skeletons. We have developed an algorithm that generates a kind of the optimal movements of hands and fingers at the piano performance. The optimal movements are obtainable by 1) finding the most appropriate finger assignments, 2) finding the smallest hand movement to play, and 3) calculating the finger position and bend angles to attack the key. The appropriate hand and finger movements in piano performance, obtained and shown in understandable 3D animations, will be quite useful for students in piano lesson. Another aim of this research is to realize a humane performance by computer. In this system, the sound is generated as a result of the interaction of fingers and a keyboard in the virtual space. So it is easy to modify the character of performance by changing the physical characteristics of the hand and fingers. This special feature will be useful to produce more realistic (humane) sounds of music than that of the computer music of today
