The Chowndolo is an instrument based on a magnetic pendulum whose trajectories are altered by magnets placed underneath the device. This creates unstable patterns of oscillation which are translated into synthesis parameters and sound. The magnets below the pendulum can be arranged to compose new shapes: different configurations will modify the pendulum oscillations and the generated sonorities. The unstable patterns produced by the pendulum oscillations are transformed into sound, articulating a music that evolves based on the pendulum’s dance.
The magnetic fields and their interactions are revealed through nuanced tones, acting as counterpoint to the pendulum’s motion. The installation aims to make visible the invisible, letting us feel forces that we are not able to perceive. The sounds generated are entirely based on FM synthesis whose sound parameters are controlled by sensing the variations in the magnetic field.
