The aim of the present study was to apply EMG biofeedback as an auxili
ary to piano teaching techniques. We studied the changes in integrated
electromyographic activity, using the abductor pollicis brevis functi
oning as an agonist during the teaching of identical selective movemen
ts of piano playing in two groups, one with EMG biofeedback and the ot
her following traditional method of instruction. The analysis of varia
nce revealed an increase in the peak amplitude and the relaxation rate
values for the biofeedback group. These results have implications for
the application of piano playing techniques and reveal EMG biofeedbac
k as an aid in the teaching of thumb attack with the abductor pollicis
brevis as agonist.
