Program Notes
Playground, for computer-processed sound and computer-generated video, was commissioned for the dedication ceremony of the Phyllis J. Washington College of Education and Human Sciences at The University of Montana. Elementary school students were interviewed and recorded, talking in their classrooms about favorite school activities, subjects they excel at, and what jobs they want when they grow up. Recordings of their voices were filtered to extract melodic fragments and granularized to produce rhythms from their speech. Field recordings of children playing on the playground, and walking to class in the hallway, were looped and crossfaded as the background for the piece. The visuals were inspired by the textured layers of the audio, along with the abstracted evolution of the words spoken by the children. The animation dynamically reacts to the sound design, creating an organic connection between the music and the video.
