STATEMENTS The EMG and EEG features of musical performance skills Biofeedback for musical performance skills
Musical performance skills rely on cognitive processes of awareness and optimal muscle activation without increasing the tension of muscles which do not participate in the execution. (Bernstein, 1967)
Skilled musicians use much less motor areas of brain than non musicians (Lotze M. & al. 2003) Alpha EEG/EMG BFB in musicians; COST B27 Meeting, Swansea, UK, 2006
The electrophysiological indices of OPTIMAL functioning of musician-performer (Petsche & Etlinger, 1998, Hassler 2000, Bazanova & al 2003, Bazanova &Kondratenko, 2005)
Biofeedback in training for musical performance EMG - Biofeedback reduces on target muscle tension of musicians performers (Hale,1981; Zinn et Zinn, 2003; Paterson et al 2005) Theta/alpha training for musicality Egner,Gruzeleir 2003
