About the image:
Tonoscope image of the vowel ‘a’ in sand. The tonoscope was constructed to make the human voice visible without any electronic apparatus as an intermediate link. This yielded the amazing possibility of being able to see the physical image of the vowel, tone or song a human being produced directly. Hans Jenny called this new area of research cymatics, which comes from the Greek kyma, wave. Cymatics could be translated as the study of how vibrations, in the broad sense, generate and influence patterns, shapes and moving processes.
