The purpose of this study is to investigate the possibilities of musical communication. To achieve this purpose，the “inner time” and the “rhythm,” which Schutz mentioned in his thesis of music, are considered. He discussed in “Making Music Together: A Study in Social Relationship” how “making music together” was achieved. He pointed out that all possible communication required an experience of the “We,” and the foundation of the experience was “sharing of the Other's flux of experiences in inner time.” Although he considered such foundation of people’s activity by phenomenological analysis, he did not refer to the “inner time” itself. This study, therefore, is concerned with events that occur in the “inner time” referring to Husserl’s phenomenology. How do individuals communicate with other people through the “inner time”? Schutz only mentioned that the clue to this question was the “rhythm.” This study shows a phenomenological structure of the synchronization between bodies in a musical process based on Husserl’s and Schutz’s theories. The synchronization occurs by workings between the “rhythm of music” and the “rhythm of physiological events within one’s body.” Musical communication, thus, is founded on the workings between the “rhythms” and sharing the “fabric woven by consciousness of retention” with others in the “inner time.”
