Composition for a Prairie Landscape

Lorraine Oades and Cristobal Urbina

Composition for a Prairie Landscape was presented at Drive-In, curated by Tulle Ruth Koefoed-Jespersen, Olso, Norway.This stereo work is made from sounds generated by a DIY glass harp, where musical notes are made by means of water and friction. The audio vibrations created by a continual circular motion result in oscillating sine waves that are at times pure in tone and other times contaminated by the friction used to create each note. Because the audio is analog the sounds seem to emanate from within the landscape, creating a quietly disturbing soundtrack that rises up from the ground and combines naturally with the other acoustic events that take place there.
