Contrasts of fragments.

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运动协调问题，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）的影响的相关研究仍较为匮乏。本研究以奥吉莉亚变奏中的阿拉贝斯克（Arabesque）漫步段落为分析对象，首先将其作为非嵌入音乐语境的舞乐片段，随后分别在两种不同的音乐语境下将其作为嵌入音乐语境的舞乐片段展开分析。鉴于上述片段的音乐结构特征，片段间与片段内部均存在模式重复现象。我们邀请了4名舞者，令其在12次连续演出中完成这3个舞乐片段的表演。研究人员提取了音乐节拍，并采用圆线性平滑回归建模与循环统计方法，将其与舞者足跟动作的微定时数据进行对比分析。研究结果显示，在SMS的微定时预判过程中，片段内部的重复效应以及片段间的音乐语境效应均具有显著影响。本研究的方法为未来开展感觉运动同步动态特性相关的研究提供了一套分析框架。
