Abstract
Motivated by the recent Reinhardt's experiments for a therapeutic purpose that suggested the heartbeats of cancer patients were synchronized with music, we attempt to explore if the heartbeats of normal individuals are synchronized with music of decreasing tempo, and also its physiological effect. Based on the tool verifying synchronization between music and heartbeats, we found that the heartbeats of normal individuals are synchronized with tempo of our music stimulus. Furthermore, we suggest, in our experiment, that the synchronization affects autonomic nervous activity related to relaxation in physiological state.
