D. Keller - touch'n'go: Ecological Models in Composition


touch’n’go is a fifty-minute tape and text piece, published as an enhanced compact disc, and as a custom CD-ROM. The CD-ROM includes the eleven sections of the piece, short Spanish and English texts - in HyperText Language Markup format - for each section, Csound code used to produce the sound material with most of the necessary samples. touch’n’go is the first attempt to apply an ecological approach in composition. This approach draws from soundscape techniques, physical models, and ecological models, expanding the existing palette of tools for synthesis and transformation of everyday sounds.


I would like to thank the people that helped me plough through my work during my stay in Vancouver: (in chronological order) Hildegard Westerkamp, Barry Truax, Tanya Petreman, Chris Rolfe and Trude Heift, Martin Gotfrit, my big Argentinean and Brazilian family, Ana Lúcia and Nahuel. I would also like to thank Dave Murphy for helping me put together the WWW version.

This project was partially funded by the School for the Contemporary Arts, Simon Fraser University. Sections of this work were presented at the International Computer Music Conference (Ann Arbor, 1998) and at the XII Colloquium on Musical Informatics (Gorizia, 1998).
