Each planet orbits the sun at its real relative speed. When it completes an orbit, it triggers a musical note — an ever-shifting ambient composition driven by the mathematics of our solar system.
Mercury's 88-day orbit is compressed to 2 seconds at 1× speed. Neptune takes ~23 minutes per orbit.

Notes map from each planet's dominant reflected light wavelength. Bluer = shorter wavelength = higher pitch. All notes are in the E minor pentatonic scale.
