Increasingly more advanced technology has allowed for novel applications of distributed agency and collective processes, such as remote and real-time musical negotiation/creation. Such affordances have had repercussions on long-established binaries such as composer/performer, composed/emerging, and top-down/bottom-up processes. This workshop explores these themes using a game-based approach to performance-driven music systems whereby, notwithstanding the preservation of some notion of authorship, a number of co-authors can negotiate in real-time the unfolding of the music, via non-linear narratives and processes. Ideas and concepts presented are inspired by Robert Rowe’s work on interactive music systems. Please visit his website for more information. Part I deals with Music Composition Systems and Response Methods, whereas Part II focuses on distributed agency over sound processes, using a networked music performance paradigm.
