Since telecommunication can never equal the richness of face-to-face interaction on its own terms, the most interesting examples of networked music go beyond the paradigm of musicians playing together in a virtual room. The Open Sound Control protocol has facilitated dozens of such innovative networked music projects. First the protocol itself is described, followed by some theoretical limits on communication latency and what they mean for music making. Then a representative list of some of the projects that take advantage of the protocol is presented, describing each project in terms of the paradigm of musical interaction that it provides.
