Variable 4 is an 8-speaker outdoor sound installation which 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 24 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 speed, rainfall, solar radiation, humidity, tropospheric variance, temperature, and more.
