A Music generating System Based on Network Theory
This paper is the first scholarly presentation of NetWorks (NW) an interactive music generation system that uses a hierarchically clustered scale free network to generate music that ranges from orderly to chaotic. NW was inspired by the Honing Theory of creativity, according to which human like creativity hinges on (1) ability to self organize and maintain dynamics at the 'edge of chaos' using something akin to 'psychological entropy' and (2) the capacity to shift between analytic and associative processing modes. At the 'edge of chaos' it generates patterns that exhibit emergent complexity through coherent development at low, mid, and high levels of musical organization, and often suggests goal seeking behavior. The architecture consists of four 16node modules: one each for pitch, velocity, duration, and entry delay. The Core allows users to define how nodes are connected, and rules that determine when and how nodes respond to their inputs. The Mapping Layer allows users to map node output values to MIDI data that is routed to software instruments in a digital audio workstation. By shifting between bottom up and topdown it shifts between analytic and associative processing modes.
