Ensemble musicians engage with each other visually through glances and body motion. We conducted a case study to test how string quartet musicians would respond to playing conditions that were meant to discourage or promote visually communicative behaviour. A quartet performed in different seating configurations under rehearsal and concert conditions. Quantity of head motion was reduced when musicians' gaze was constrained. Differences in gaze and body motion between musicians reflected their musical roles in the ensemble. Overall, our findings suggest that gaze and motion dynamics vary within and between performances in response to changing musical, situational and social factors.

合奏音乐家通过眼神和身体动作在视觉上相互交流。我们进行了一项案例研究，以测试弦乐四重奏音乐家如何应对旨在阻止或促进视觉交流行为的演奏条件。在排练和音乐会条件下以不同座位配置进行的四重奏。当音乐家的视线受到限制时，头部运动的数量就会减少。音乐家之间凝视和身体动作的差异反映了他们在合奏中的音乐角色。总的来说，我们的研究结果表明，随着音乐、情境和社会因素的变化，在表演中和表演之间的凝视和动作动态会有所不同。
