Improvised sound work is one of the key areas of inter-generic hybridity in contemporary music. Any attempt to identify a social role and agree on a cultural meaning for such improvisational practice must grapple first with issues of definition. These issues are especially acute for emerging hybrid practices because their practical development outstrips the ability of the available critical/ideological structures to provide useful and generally agreed definitions for them.
