Notes

  • Program notes: 

    Prometheus and the Nodding Donkey was commissioned by Redshift Music for a performance in Blusson Centre, the Spinal Research wing of the Vancouver General Hospital. It was composed with the unique spatial configuration of the space in mind, though other configurations are possible. The musicians are placed surrounding the audience on three vertical levals, and so a structural feature of the work is the movement of the sound in space, contrasting actual physical movement with imagined psychoacoustic movement. Some of the gestures in the piece transfer between performers on different vertical levels, while the spectral movement of the musical texture progresses in the opposite direction. Other sections of the piece take advantage of psychoacoustic phenoma, such as the precedence effect, where sound is emanating from all directions, but changes in dynamics cause the listener to perceive directionality. Many of the specific gestures and textures of the piece are inspired by the physical movements of various real-world objects, such as the nodding-donkey style oil jack of the title, flowing water, and hinges. The materials in the piece come from a concern for acoustic ecology and the changing soundscape - and how these are related to broader ideas about human interaction with the environment.
