In Ecology without Nature I talk about the Aeolian as an effect of ambient poetics-the illusion that sound, imagery etc. is emanating from an unseen source, like wind in sympathetic strings.
I like to joke that the power lines outside my home are a very large scale Aoolian harp, but the cables give off extremely low hums, almost imperceptible, but definitely unsettling. Click the info button on the left hand corner to release more examples of ambient wind instruments.
