6.1 An example of pre- and post-training comparison with improved coordination

This video set presents a pre- and post-training comparison of an overseas conservatory piano student’s performance to assess the impact of targeted technical intervention. It highlights observable improvements in wrist flow, coordinated upper-limb movement, and overall technical refinement following participation in the intervention.The baseline clip shows the student's playing at her entry level. While competent for her advanced stage, coordination between proximal (shoulders, elbows) and distal (wrists, fingers) segments appears less integrated, contributing to a somewhat less fluid overall motion.In the follow-up recording, a clear improvement is evident, particularly in enhanced wrist flow and smoother integration of the kinetic chain. As noted by an evaluating teacher: "演奏速度轻快，音乐充满活力。手指已形成一定的肌肉记忆。肩部、肘部和腕部的协调性也更加紧密，触键和音色精准稳定。" (Translation: The performance speed is lively, the music is energetic, and the fingers have formed a certain muscle memory; the coordination between the shoulders, elbows, and wrists appears much tighter, resulting in accurate and stable keystrokes and tone colour.)This comparative set serves as compelling evidence of how targeted, embodied training can yield measurable refinements even at an advanced level, supporting the value of ongoing technical refinement and body awareness in higher-education piano study. While familiarity with the repertoire and natural increases in speed would occur over time regardless of the intervention, the focus is specifically on physiological optimisation. Although subjective assessments of tone quality varied among faculty, the research team favoured the post-training rendition for its greater fluidity, precision, and naturalness in hand-wrist-arm gestures. The student’s self-reflections further identified wrist movement as her most pivotal area of growth.These videos form part of a broader research project investigating the development of coordinated movement in piano performance, with applications in piano pedagogy, injury prevention, and performance enhancement.
