What is cymatics?
Cymatics comes from the Greek kyma, a wave. Scatter sand on a metal plate and make the plate ring, and the grains move off the parts that shake and gather along the lines that stay still. The result is a sharp figure of lines, rings and stars, which changes to a more complex one as the pitch rises. Liquids and pastes on a vibrating membrane form ripples, cells and rotating shapes.
The physics is that of standing waves: the pattern depends on the shape, size and stiffness of the plate as much as on the note. Jenny photographed hundreds of such figures and wondered whether vibration shapes living forms as well. That wider idea, and the claim that particular sounds heal by imposing their pattern on the body, goes beyond what the experiments show. The figures themselves are real, repeatable and beautiful.
On the tree of the hidden arts: Sound and mantra.
What sets Cymatics apart
Cymatics stands out because its evidence is a picture anyone can reproduce with a plate, a speaker and a handful of sand. The same note gives different figures on plates of different shapes, a point often left out when a figure is presented as the form of a sound. Chladni used the figures to do exact science, and Sophie Germain won a Paris Academy prize in 1816 for a mathematical theory of them. Violin makers still dust fine powder or glitter on the plates of an instrument to tune them.
- Word: from Greek kyma, a wave; German Kymatik
- Coined by: Hans Jenny, 1904 to 1972, Swiss physician
- Sand figures: Chladni figures, after Ernst Chladni, 1787
- Earlier sighting: Robert Hooke, with flour on a glass plate, 1680
- On liquids: Faraday waves, described by Michael Faraday in 1831
- Where sand rests: on the nodal lines, the parts of the plate that do not move
Often mistaken for something else: A Chladni figure is the sand pattern on one plate at one pitch; cymatics is Jenny's wider name for all such patterns and for his idea that vibration gives rise to form.
The story behind Cymatics
Robert Hooke saw nodal patterns in flour on a glass plate in 1680. Ernst Chladni made them famous in a book of 1787, bowing metal plates with a violin bow, and demonstrated them across Europe; Napoleon had him perform in Paris. Michael Faraday described the ripples on a vibrated liquid in 1831. Hans Jenny, a physician and follower of Rudolf Steiner, published Kymatik in two volumes in 1967 and 1972, using crystal oscillators to control the tone.
Why Cymatics matters
Cymatics gives sound a shape the eye can check, which is why its images open so many talks on music, geometry and healing.
How to read Cymatics
Teachers use the figures to show standing waves, instrument makers to test the plates of violins and guitars, and artists as a way of drawing with sound.
Cymatics in practice: an example
A science museum shows the effect with a square plate and a loudspeaker: turn the dial and the sand jumps from one figure to the next.
Where readings of Cymatics go wrong
A pattern in sand shows how a plate vibrates. It is not evidence that a tone arranges cells or water in the body.

Common questions
What is cymatics?
It is the study of the patterns that vibration makes visible in a material such as sand, powder or water. The term was introduced by Hans Jenny in 1967; the classic sand patterns are called Chladni figures.
Why does sand form patterns on a vibrating plate?
A ringing plate has moving regions and still lines between them, called nodal lines. Sand is thrown off the moving parts and comes to rest on the still lines, so it draws the outline of the vibration.
Does cymatics prove that sound can heal?
No. It shows that vibration organises loose material on a surface. Whether sound has effects on health is a separate question that needs clinical study, and the sand figures do not answer it.
