Increase in synchronization of respiration by repeatedly listening to the same piece of music

We found that participants tend to change their respiration at specific timing in listening to the same piece of music. Although the timing of concurrences differs between participants, such frequency increased within a participant as he or she gain experience on the piece. Our result supports that there is a strong relationship between respiration and music as studies had shown and besides, timing factor seems to be important as tempo for the relationship. This will help us design a new type of music interfaces, which should utilise physiological data.
