Résumé
Choir singing is a widely practiced activity that offers multiple benefits, as demonstrated by psychophysiological studies in both healthy and pathological populations. However, the processes underlying these outcomes are still not fully understood. Yet, advances in portable multimodal systems enable a more thorough investigation of these effects. The present study thus aimed to examine neurophysiological and behavioural responses of choirmasters and singers under various conditions of visual coupling. Preliminary results highlight the importance of combining different methods of analysis and metrics to better understand the intricate phenomena at play in this beneficial practice.
