We discuss a new method of distributed jam session over network by employing the style of club DJ performance. DJ's are music performers, and they construct a music piece by combining materials prepared beforehand one by one. As a result, two and more DJ's join to complete a musical content in a session by the fusion of individual materials. Usual Internet streaming systems with client/server architecture are not appropriate under such an environment that each performer has a symmetric role in a jam session, because the control of time line cannot be defined in a bottom-up fashion. We here propose a feasible way of the distributed jam session over the Internet by modeling actual jam session as a document aggregation and binary relation among those documents over time line. We introduce a notion of scene and its synchronization to achieve a jam session, and employ RDF/RSS to represent a session. In our approach, we divide a session into subsections based on a basic structure that musical contents hold, and allocate musical phrases to the subsections to complete a whole session. By the experimental session, we have confirmed the effectiveness of our method, and also obtained an observation of quantitative features of the distributed jam session.
