  3. "Never must your fingers stand in the way of your artistic interpretation," Carl Czerny

  4. STATEMENTS The EMG and EEG features of musical performance skills Biofeedback for musical performance skills

  5. 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)

  6. 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

  7. The electrophysiological indices of OPTIMAL functioning of musician-performer (Petsche & Etlinger, 1998, Hassler 2000, Bazanova & al 2003, Bazanova &Kondratenko, 2005)

  8. 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

  9. EEG Sensors Biofeedback signal Monitor presentation Interface EMG Sensors Alpha EEG/EMG BFB in musicians; COST B27 Meeting, Swansea, UK, 2006

  10. Alpha peculiarities (Kaiser, 2001; Hanslmayr et al., 2005) Alpha EEG/EMG BFB in musicians; COST B27 Meeting, Swansea, UK, 2006

  12. AIMS To compare responses of musicians with high and low individual alpha peak frequency to usual practice and practice combined with long term simultaneous individual alpha increasing and EMG decreasing biofeedback training. To investigate the impact of alpha-EEG/EMG biofeedback on electrophysiological and psychometric parameters in musicians. Alpha EEG/EMG BFB in musicians; COST B27 Meeting, Swansea, UK, 2006
