The term Cymatics was coined by Dr Hans Jenny (1904-1972) and is the study of visible sound and vibration. Dr Jenny was a Swiss doctor, artist, and researcher who pioneered the science of Cymatics. He demonstrated what happens when certain materials like sand, salt, water, and other viscous substances, are placed on vibrating metal plates and membranes, which mirrored forms found throughout nature, art, and architecture. These patterns were created using simple sine wave vibrations (pure tones) within the audible range. So what you see is a physical representation of vibration, or how sound manifests into form through the medium of various materials.
