For this composition, I used the timeframe of the sunset on September 21, 2023, to record and transform data about the temperature, humidity, air pressure, and light intensity changes into sound. The recorded data, displayed on this site when you click ‘load sunset data,’ was used to define parameters like pitch and intensity in the recording. Part 1 presents the extended moment of fading lights in the landscape by generating sound from the most radical changes in the values. Part 2 is a free improvisation using the sensor data after the dark settled, when the incoming environmental data stagnates.
