Remembering the future: An overview of co-evolution in musical improvisation
Musical improvisation is driven mainly by the unconscious mind, engaging the dialogic imagination to reference the entire cultural heritage of an improvisor in a single flash. This paper introduces a case study of evolutionary computation techniques, in particular genetic co-evolution, as applied to the frequency domain using MPEG7 techniques, in order to create an artificial agent that mediates between an improvisor and her unconscious mind, to probe and unblock improvisatory action in live music performance or practice
Crowdsourcing the corpus: using collective intelligence as a method for composition
The author describes the practical application of crowdsourcing human intelligence as a form of collaborative music-making. Spectral decomposition of an original recording is used to derive components from original audio, and these are then offered as on-line tasks in which contributors are asked to record their own interpretations of each component. Components are then gathered in order to re-synthesize the original corpus, which is used to build an improvisation system. The author uses Bernard Stiegler's ecology of attention paradigm to situate crowdsourcing as an emerging form of public participation in music-making and Glenn Gould's ideas on performance and public access to position this participation as an act of composition. The work is offered as an illustration of the author's individual process as a composer for finding new notational pathways for collaborative practice
