Neurofeedback displayed significant improvements in the
overall quality of the musical performance. Few investiga-
tions showed that predictors of good psychomotor per-
formance are low integrated EMG of muscle non-
participating in execution and an increased EEG alpha
activity (Bazanova et el, 2003; Pantev et al, 1998; Petsche
& Etlinger, 1998).
The main objectives of the present investigation was to
study the impact of simultaneous individual alpha-EEG
stimulating and EMG decreasing biofeedback (Alpha-
EEG/EMG BFB) on electrophysiological indices in musi-
cians by comparing responses of musicians to usual prac-
tice and practice combined with biofeedback training.
Materials and methods
The aim of the neurofeedback training of 51 musical stu-
dents was “to attain a state at which achieving high quality
musical performance would be complimented with a feel-
ing of easiness and comfort”. Firstly, they had their usual
practice (30 minutes), followed by rest and another 30-
minutes lasting practice combined with Alpha-EEG/EMG
BFB. Efficiency of Alpha EEG/EMG BFB session was calcu-
lated as the ratio between the sum-duration of the success-
ful periods during the Alpha EEG/EMG BFB session and
the whole length of the session.
Usual practice caused decrease while practice combined
with biofeedback increase in individual alpha-activity
indices in the alpha-2 band. In the same time usual prac-
tice increased muscle tension, while practice with biofeed-
back decreased EMG. The score of self-estimated “quality
of sound” was higher after practice combined with alpha-
EEG/EMG-BFB than after usual practice (p=0.021). Effi-
ciency of the biofeedback depended on the power in
alpha-2 band, individual alpha peak frequency, individ-
ual alpha band width and individual amount of alpha
suppression in response to open eyes.
Enhanced somatosensory and auditory feedback during
performance on the instrument facilitates the online
modification of musical execution skill
