The change in the synchronization between heartbeat and music

In this study, the change in the synchronization between heartbeat and music was investigated. The phenomena of the synchronization between human heartbeat and musical tempo has been reported in several previous studies, however, it has not yet been fully investigated including the effect of changing the tempo of musical piece on the synchronization. In the experiment, the subjects were exposed to musical pieces in which the tempo was manipulated to gradually increasing (named “Up” condition), decreasing (“Down”) and constant (“Flat”). Through the analysis by our developed software, Cardio-Music Synchrogram, the shortest length of the total synchronization periods was observed in Flat condition. Furthermore, the temporal change in the synchronization was investigated.
