Variable 4 is an outdoor sound installation that translates weather conditions into musical patterns in real time. Using meteorological sensors connected to a custom software environment, the weather itself acts as conductor, navigating through a map of twenty-four specifically-written movements.
Every aspect of the piece, from broad harmonic progressions down to individual notes and timbres, is influenced by changes in the environment: wind, rainfall, sunlight, humidity, and temperature. The resultant composition is performed over an indeterminate duration through eight loudspeakers integrated into the landscape.
