Cymatics
Encyclopedia
Cymatics is the study of visible sound and vibration, a subset of modal phenomena
Normal mode
A normal mode of an oscillating system is a pattern of motion in which all parts of the system move sinusoidally with the same frequency and with a fixed phase relation. The frequencies of the normal modes of a system are known as its natural frequencies or resonant frequencies...

. 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. 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 or advanced such as the CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.

Etymology

The generic term for this field of science is the study of modal phenomena, retitled 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 have on matter.

History

The study of the patterns produced by vibrating bodies has a venerable history. One of the earliest to record that an oscillating body displayed regular patterns was Galileo Galilei
