Have been working on a piece of fiction that’s required some research into Wales (colliers, eisteddfods, Hay-on-Wye, relatives still there, preparing to go see). In the midst of this, a neat confluence, I learned about Weathersongs. English composer Richard Garrett uses an installation comprising an automatic weather station connected, via a computer, to an electronic musical instrument to gather data from the weather station regarding air pressure, temperature, rainfall, humidity, wind speed and direction and uses it to compose music in near real time.
Thus, when the wind blows, phrases are generated whose pitch, intensity and statistical density reflect wind speed and direction; other notes change with the rise and fall of temperature or pressure; and random percussive events occur with changes in rainfall. While this is not a one-to-one sonification, the system does respond to dynamic changes in a representative fashion.
Garrett later edited these part-field recordings/ part-generative scores into tracks on his album, Weathersongs Volume 1: Days in Wales. At the website, you can listen to extracts from the recording as well as mp3s of the raw, unedited output.
