Cymatics is the study of visible sound and vibration, typically on the
surface of a plate, diaphragm or membrane.
Direct ocular viewing of vibrations involves exciting inorganic matter
such as particulate matter, pastes (both magnetic and non magnetic)
and liquids under the influence of sound, although recent research has
extended the range of media to include organic matter and the range of
viewing has been extended to include the light microscope.
The generic term for this field of science is the study of 'modal
phenomena,’ named 'Cymatics' by Hans Jenny, a Swiss medical doctor and
a pioneer in this field. The word 'Cymatics' derives from the Greek
'kuma' meaning 'billow' or 'wave,' to describe the periodic effects
that sound and vibration has on matter.
The apparatus employed can be simple, such as a Chladni Plate (a flat
brass plate excited by a violin bow) or advanced such as the
CymaScope, a laboratory instrument that makes visible the inherent
geometries within sound and music.
