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.

本视频集围绕一位海外音乐学院钢琴专业学生的演奏展开训练前后对比，旨在评估针对性技术干预的实际效果。该数据集清晰呈现了干预后学生在腕部动作流畅度、上肢协同动作及整体技术打磨层面的可观测提升。
基线片段记录了该学生入学初始水平的演奏状态：尽管以其进阶演奏阶段的标准而言，她的演奏已属合格，但近端（proximal，肩部、肘部）与远端（distal，腕部、手指）肢体节段的协同整合度仍有不足，导致整体动作流畅度有所欠缺。
在后续随访录制的演奏片段中，进步尤为显著，尤其体现在腕部动作流畅度的提升与动力链（kinetic chain）协同整合的优化。正如评估教师的评价所示：「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。」
本对比数据集有力佐证了：即便处于进阶演奏阶段，针对性具身化训练（embodied training）亦可带来可量化的技术提升，印证了高等音乐学院钢琴学习中持续打磨技术与培养身体觉知能力的重要价值。尽管无论是否施加干预，学生对曲目熟练度的提升与演奏速度的自然增长都会随时间自然发生，但本研究的核心聚焦于生理机能优化（physiological optimisation）。尽管参与评估的教师群体对音色的主观评价存在一定差异，但研究团队更认可训练后的演奏版本，因其手部-腕部-手臂的动作更具流畅性、精准性与自然度。学生的自我反思亦进一步指出，腕部动作是其进步最核心的领域。
本系列视频隶属于一项更宏大的研究项目，该项目旨在探究钢琴演奏中协同动作的发展规律，其研究成果可应用于钢琴教学法、演奏损伤预防以及演奏表现提升等领域。
