Effect of musical improvisation on inter-brain wave synchronization

Abstract

This article investigates brain synchronization during the musical improvisation. Techniques such as phase locking value (PLV) and envelope correlation were used to analyze the electroencephalography (EEG) signals of 5 pairs of musicians playing together. The study found synchronization in frequency bands (delta, theta, alpha, beta1, and beta2) during performance and improvisation above random fluctuations. The results suggest that both following a score and improvise, involve synchronization between brains and highlight the potential influence of music on brain activity and interpersonal connections. However, the mechanisms by which this synchronization occurs are not clear. Therefore, further research is needed to explore more specific experimental approaches.
