This is four tracks from an album of music made with a harmonograph connected to a modular synthesiser via sensors. A harmonograph is an 18th century scientific device that uses pendulums to create drawings that illustrate musical harmony. For this album I set the pendulums to near unison, so they gently swing in and out of phase with each other. Each time the machine creates a unique drawing, it also creates a unique musical composition to accompany it. The duration of each track is the exact time it takes for the pendulums to run down at which point the drawing is complete. You can download the entire 17 track album from my bandcamp page - just click the button to be whisked away there.
