The ability to coordinate with others is fundamental for humans to achieve shared goals. Often, harmonious interpersonal coordination requires learning, such as ensemble musicians rehearing together to synchronize their low-level timing and high-level aesthetic musical expressions. We investigated how the coordination dynamics of a professional string quartet changed as they learned unfamiliar pieces together across eight trials. During all trials, we recorded each musician's body sway motion data, and quantified the group's body sway similarity (cross-correlation) and information flow (Granger causality) on each trial. In line with our hypothesis, group similarity increased, while group information flow decreased significantly across trials. In addition, there was a trend such that group similarity, but not information flow, was related to the quality of the performances. As the ensemble converged on a joint interpretation through rehearsing, their body sways reflected the change from interpersonal information flow for coordinative mutual adaptations and corrections, to synchronous musical coordination made possible by the musicians learning a common internally based expressive interpretation.

创建共享的音乐解释：一起学习不熟悉的音乐时协调动态的变化

与他人协调的能力是人类实现共同目标的基础。通常，和谐的人际协调需要学习，例如合奏音乐家一起排练以同步他们的低级时间和高级审美音乐表达。我们调查了专业弦乐四重奏在八次试验中一起学习不熟悉的乐曲时协调动态如何变化。在所有试验中，我们记录了每位音乐家的身体摇摆运动数据，并在每次试验中量化了该组的身体摇摆相似性（互相关）和信息流（格兰杰因果关系）。与我们的假设一致，群体相似性增加，而群体信息流在试验中显着下降。此外，有一种趋势是群体相似性，但不是信息流，与演出质量有关。当合奏团通过排练汇集到共同解释时，他们的身体摇摆反映了从协调相互适应和纠正的人际信息流到音乐家学习共同的内部表达解释使同步音乐协调成为可能的变化。
