The evolution of networked audio technologies has created unprecedented opportunities for musicians to improvise with instrumentalists from a diverse range of cultures and disciplines. As network speeds increase and latency is consigned to history, tele-musical collaboration, and in particular improvisation will be shaped by new methodologies that respond to this potential. While networked technologies eliminate distance in physical space, for the remote improviser, this creates a liminality of experience through which their performance is mediated. As a first step in understanding the conditions arising from collaboration in networked audio platforms, this paper will examine selected case studies of improvisation in a variety of networked interfaces. The , , author will examine how platform characteristics and network conditions influence the process of collective improvisation and the methodologies musicians are employing to negotiate their networked experiences.
