An EEG study of creativity in expert classical musicians

TL;DR

This study investigates the relationship between EEG alpha activity and creativity in expert classical musicians during different performance contexts, highlighting neural correlates of improvisation and stress.

Contribution

It demonstrates real-time EEG monitoring of musicians during live performances, revealing correlations between alpha power, improvisation, and stress levels.

Findings

Alpha power increases during improvisation

Negative correlation between alpha and stress

Feasibility of real-time EEG visualization during live music

Abstract

Previous research has shown positive correlations between EEG alpha activity and performing creative tasks. In this study, expert classical musicians (n=4) were asked to play their instrument while being monitored with a wireless EEG headset. Data was collected during two rehearsal types: (a) in their regular, fixed ensemble;; (b) in an improvised, mixed ensemble with unfamiliar musicians and less rehearsal time. A positive correlation was found between alpha power and the improvised setup (p<0.01, d=0.4). A positive correlation was also found between alpha power and more intense play (p<0.01, d=0.2). There was a negative correlation between alpha power and arousal due to stress, e.g., frowning after playing a false note (p<0.01, d=0.6). Finally, the real-time capabilities of wireless EEG monitoring were explored with a data visualisation during live performance on stage.
