The Ko-Tone is a kinetic machine conceived by a collective of artists to be driven purely by gravity to perform a musical composition.

Alluding to an allegory of man in harmony with nature, a free falling wooden ball traverses a circumferential pathway over 67 xylophonic keys to automatically play out the tune Jesus, joy of man’s desiring, by Johann Sebastian Bach.

Much like the disparate mix of its creators – artist, composer, and technician, the Ko-Tone is fluid in its interpretation as kinetic art or musical instrument.
