Gaia (2006)

including *Electronic Sounds, Animals, Birds, Insects, Eco-environmental sounds, Weather sounds, and Solo Violin 

The word gaia is Greek for earth, and was first used by James Lovelock to describe the earth's surface as a single planetary ecosystem. The electronic sounds are realizations of various planetary phenomena, including the earth’s rotation, tides, light-dark periods, etc. that oscillate continuously throughout the life of the planet. Other phenomena vibrate in repeated segments of similar or varied durations, separated by periods of inactivity. These oscillations include, but are not limited to, ocean waves, brain waves, circadian rhythms. Finally, there are sounds that occur for a finite duration, typically once only, on a particular region of the earth, within a 24 hr. period. These include phenomena such as high or low pressure fronts, atmospheric waves, seismic waves, cyclones, tidal waves. Each of the four categories of acoustic phenomena – air, liquid, solid, organic substance – has its own frequency that has been transposed to within the human range of hearing, and has been assigned a unique quality of sound, or timbre. Eco-environmental sounds include entire ecosystems such as the everglades, Amazon rain forest, etc. Weather sounds include earthquake, lava flow, thunder, rain, ocean waves, etc. The solo violin music consists of borrowed segments from a recording of my Solo Music No. 2 for Unaccompanied Violin recorded by Marla Rathbun in 2004. The violin excerpts represent the interaction of humans with the planetary ecosphere.

* The electronic sounds were originally constructed by Josh Caswell and myself for our collaborative sound installation Voices of Earth
