Abstract: Aim: The aim of the present study is to examine the relaxation effect of music, as measured by heart rate variability (HRV) and electroencephalography (EEG) in subjects with or without music training, in order to provide a clear picture of how music promoting relaxation in autonomic nervous system (ANS) and central nervous system (CNS). Design: The study used a 2x2 factorial design in which 79 Chinese healthy subjects aged from 18-30 were recruited. The subjects were randomized into two groups, Listen Group and Not Listen Group, and further categorized into two groups, trained subjects or not trained subjects. The study was composed of four sessions: baseline, 1st music, 2nd music and post-music silence. While the music selected by subjects will be played twice in "Listen" group, no music will be played in "Not Listen" group. HRV and EEG recording were obtained with subjects lying supine throughout the whole procedure. Results: Subjects in Listen Group showed significant decrease in C-STAI (state). Respiratory rate was slowed down significantly. HRV LF n.u. power was decreased significantly during the 1st music. HRV HF n.u. power and EEG theta power was increased during the 2nd music and the increase was most significant at post music silence. Subjects with music training appeared to be less relaxed than those without training. Conclusions: Listening to music can induce relaxation in people with or without music training, most significantly at post music silence.
