熟练的钢琴演奏需要相当大的运动控制来完成专业音乐家中常见的高水平的时间和力量精确度，他们通过数十年的练习获得钢琴技巧。当钢琴家以非常快的速度演奏时，手指运动效率尤其是一个重要因素。我们的文件手指运动运动学的高度熟练的钢琴家，因为他们在非常快的节奏进行了五指旋律。一个三维运动捕捉系统跟踪手指关节的运动，手，和12位钢琴家的前臂，他们在数字钢琴上以连续更快的速度（7-16个音调/秒）演奏，直到他们决定停止。关节角轨迹计算的所有相邻的手指指骨，手，和前臂（手腕角）表明，掌指关节贡献最多的垂直指尖运动，而近端和远端指间关节移动稍微相反的运动目标（手指伸展）。组合手指关节角度的效率测量对应于钢琴家表演的时间准确性和精度：具有更有效的快速移动的钢琴家在时间和力测量方面表现出更高的精度。在整个克里思条件下，击键效率和个体关节贡献保持稳定。钢琴家之间的个体差异支持了这样一种观点，即成功的快速演奏需要高效率。
Skilled piano performance requires considerable movement control to accomplish the high levels of timing and force precision common among professional musicians, who acquire piano technique over decades of practice. Finger movement efficiency in particular is an important factor when pianists perform at very fast tempi. We document the finger movement kinematics of highly skilled pianists as they performed a five-finger melody at very fast tempi. A three-dimensional motion-capture system tracked the movements of finger joints, the hand, and the forearm of twelve pianists who performed on a digital piano at successively faster tempi (7–16 tones/s) until they decided to stop. Joint angle trajectories computed for all adjacent finger phalanges, the hand, and the forearm (wrist angle) indicated that the metacarpophalangeal joint contributed most to the vertical fingertip motion while the proximal and distal interphalangeal joints moved slightly opposite to the movement goal (finger extension). An efficiency measure of the combined finger joint angles corresponded to the temporal accuracy and precision of the pianists’ performances: Pianists with more efficient keystroke movements showed higher precision in timing and force measures. Keystroke efficiency and individual joint contributions remained stable across tempo conditions. Individual differences among pianists supported the view that keystroke efficiency is required for successful fast performance.
