Several studies have addressed motor coordination in dance, but few have addressed the influence of musical context on micro-timing during sensorimotor synchronization (SMS) in classical ballet. In this study, we analyze the Promenade in Arabesque of the Odile variations, first as a dance-music fragment non-embedded in a musical context, then as a dance-music fragment embedded in a musical context at two different instances. Given the musical structure of the fragments, there are repeats of patterns between and within the fragments. Four dancers were invited to perform the three fragments in twelve successive performances. The beats of the music were extracted and compared with the timing of the dancers’ heel movements, using circular-linear smooth regression modelling, and circular statistics. The results reveal an effect of repeat within fragments, and an effect of musical context between fragments, on micro-timing anticipation in SMS. The methodology offers a framework for future work on dynamical aspects of SMS.已有多项研究探讨了舞蹈中的动作协调问题，但针对古典芭蕾舞感觉运动同步（sensorimotor synchronization, SMS）过程中音乐语境对微定时（micro-timing）影响的研究仍为数不多。本研究以奥吉莱变奏段中的阿拉贝斯克姿态漫步动作为分析对象，首先将其作为未嵌入音乐语境的舞蹈音乐片段进行分析，随后将其作为两段分别嵌入不同音乐语境的舞蹈音乐片段开展研究。鉴于各片段的音乐结构，片段间及片段内部均存在模式重复现象。我们邀请四位舞者在12次连续表演中完成上述三类舞蹈音乐片段的呈现。研究提取了音乐节拍，并结合圆线性平滑回归建模与圆形统计方法，将其与舞者足跟动作的时序进行对比分析。结果显示，在SMS的微定时预判中，片段内部的重复模式存在显著影响，同时不同片段间的音乐语境亦产生了显著效应。本研究的方法可为未来针对SMS动态特性的相关研究提供分析框架。
