Sound marbling at 210Hz, 333Hz, 484Hz
Suminagashi is an ancient Japanese paper marbling technique. Sumi-e inks are dropped carefully to float on a still water surface, and then delicately affected to conceive the intended imprint. 
Combined with Cymantics by adding sound into the process,  a pure tone is applied, at various driving sinusoidal frequencies, causing different patterns to emerge on the excitatory medium. From order becomes apparent chaos, reflecting the harmonic laws of nature.
The final result is raw visualisation of sound, without the intent of aestheticization.
