Cymatics and the Effect of Sound and Music on Society
Cymatics (from Greek: κῦμα "wave") is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid.[1] Different patterns emerge in the exitatory medium depending on the geometry of the plate and the driving frequency.
The apparatus employed can be simple, such as a Chladni Plate[2] or advanced such as the CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.[clarification needed]
