Inspired by, the work of and his medical practice, Hans Jenny began an investigation of phenomena but especially the visual display of sound. He used standing waves piezoelectric amplifiers, and other methods and materials.
Cymatics was explored by Hans Jenny in his 1967 book, Kymatik (translated Cymatics).
Dr. Hans Jenny (1904-1972). Swiss physician, artist, and natural scientist."The more one studies these things, the more one realizes that sound is the creative principle. It must be regarded as primordial. No single phenomenal category can be claimed as the aboriginal principle. We cannot say, in the beginning was number, or in the beginning was symmetry, etc. These are categorical properties which are implicit in what brings forth and what is brought forth. By using them in description we approach the heart of the matter. They are not themselves the creative power. This power is inherent in tone, in sound."
