Virtual performance, Actual gesture: A Web 2.0 system for expressive performance of music contents

Musical games and social interaction music-based platform are getting always more users, which are attracted by tools to easily organize and retrieval the music contents, and by an active participation in the fruition process. In this context Web 2.0 technologies play an important role in facilitating collaborative creation, active participation, and the sharing of music contents to the large users. Our aim is to consider the expressiveness in the musical gesture in a participative way: all of user can actively perform musical pieces and express their perspective about how to tag the expressiveness of user´s musical performances in order to build a new paradigm of a (really shared) performer praxis. We justifiably believe that music gaming/learning by integrating Web 2.0 and real-time musical gesture evaluation (and not only the estimation of the exact notes played) can become more and more effective and appealing. In this paper, we present a system - namely CARO 2.0 - that integrates a software module for the active performance of music pieces into a Web 2.0 framework, in order to make easier sharing the user´s performances and experiencing new modalities of collaborative creation.
