An EEG study of creativity in expert classical musicians
  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.
