Initial investigation on alpha asymmetry during listening to therapy music

Several studies had shown that frontal alpha-asymmetry is closely related to emotions and motivation. The present study is to investigate the frontal alpha asymmetry during listening to the therapy musical piece. Electroencephalograph (EEG) was used to investigate the emotions states of relax, tense, sad or not focus. 10 participants were involved in this study. Mean power of both hemispheres was computed and the Asymmetry Relation Ratio (ARR) was calculated. From the calculation, individuals with relatively positive ratio shows more relax than the negative ratio.
