Abstract
Why is it that in experimental improvised music (EIM) anything can happen but hardly ever does? And if what musicians play is not determined in advance, what holds performances of EIM together? We address these twin questions through a combination of verbal dialog, recordings of a live performance of the Splitter Orchester and the Trondheim Jazz Orchestra, and comments on both. Drawing on theories of »participatory sense-making« in enactive philosophy, we show that while musical phenomena such as drones and grooves emerge from human interaction, they take on a life of their own as more-than-human agents. By enabling and constraining what »makes sense« in particular situations, these »emergent autonomous organizations« shape the (inter)action that gave rise to them, obtaining normative force. By the same token, however, they can also change according to musicians’ subsequent (inter)actions. EIM thus stages the emergence and transformation of norms in real time and illustrates how human action more broadly interacts with the more-than-human.
