The term Cymatics (pronounced sigh-matt-ix) was coined by Dr. Hans Jenny (1904 -1972). It is derived from the Greek word Kyma or ta kymatika meaning; matters pertaining to waves. By the term waves, Jenny was particularly wishing to point towards periodicity or cycles. Dr. Jenny was an Anthroposophist (a follower of the teachings of the Austrian philosopher, occultist, mystic and clairvoyant Rudolph Steiner 1864-1925). This work revolves around the ability to demonstrate acoustic phenomenon, which work was begun in the late 18th century by Ernst Chladni (1756-1827) and then developed further by Margaret Hughes-Watts and then taken a stage further by Jenny. The famous Chladni Figures had previously demonstrated the organising power of sound and vibration. The method was to take a metal plate and to suspend it as freely as possible and then to excite it into activity via the use of a violin bow. Most typically, this was to clamp it at its centre leaving the rest of the plate fairly free to vibrate. Placing some sand upon the surface and then bowing the plate aroused the sand particles into activity and into very beautifully organised geometric shapes. Bowing the plate at different points excited other harmonics, which further developed the resulting patterns into different, yet still ordered and repeatable, geometric or mandala-like patterns. Each single harmonic of the plate when sounded created the same pattern, which increased in complexity as one progressed along the harmonic series.

The harmonic series, or overtones, is likewise a law of nature that follows a strictly mathematical progression for the human voice, strings, and brass instruments.  This series is predictable and ordered and finds its reflection within the Cymatics phenomenon. For instance, the first overtone is known as the Octave, whilst the next overtone is a perfect Fifth and the following overtone is a Fourth. Each overtone produces an interval that gets progressively smaller as the process moves along until they are so close together that the human ear cannot detect the difference. Each succeeding Octave is also divided up in an arithmetic series. That is to say that the first Octave produces One interval (known as the Octave) and in the next Octave we find Two intervals, whilst in the next higher Octave we find Four intervals and the next Octave Eight intervals and so on.  The interval of an Octave is when the note upon which the whole series begins is reached again only vibrating at twice, four times, eight times – and so on – its original speed. Therefore, if we begin on the note C the next Octave is also called C but it is vibrating twice as fast as the original C. If the first tone is vibrating at 250 cycles per second (cps) then the Octave vibrates at 500 cps, the next Octave at 1,000 cps (4 times the original speed) and so on. The introduction of this Law into Western music is attributed to the great Sage of Samos – Pythagoras (around 400 BC) – and an entire cosmology was further developed around these musical principles by the 17th century English Rosicrucian apologist Robert Fludd (1574-1637). 

Dr. Jenny took the idea of the Chladni plate but went on to excite it using precisely measured vibrations (cps – Hertz) and amplifications (volume) via a piezoelectric effect using a crystal oscillator and then to cover the plate with various substances and finally to document his results in both photographs and films. He researched this phenomena for 14 years. The results are truly awe inspiring, breathtaking, most inspiring and enlightening. The films in particular are most stimulating. By filming the experiments, we are able to see instances of when forms arise out of chaotic substance and then return back again into what we might term the Virgin Space of Repotentialisation only to come forth again forming the same pattern (providing the tone remains the same). Here we see cyclic phenomenon taking place, where all is in constant movement. Even the formed geometric patterns are shown to be comprised of numerous particles constantly moving within those patterns – like an army of ants walking backwards and forwards within a constant shape.

Whilst Dr. Jenny, as far as I know,  didn’t apply any of his findings, regarding the effects of sound and vibration upon physical matter, within the healing realm of sound, yet, nevertheless, he laid a wonderful foundation for that work in respect of making visible the power of sound and its effects upon the world of form and matter.

“An investigation of the world in terms of cymatics throws an interesting historical light on earlier philosophies resting upon mathematical order and the relationship of sounds, musical tones and words (Heraclitus, Pythagoras, Archytas, Plato, Aristoxenos, down to Kepler and many others). Connections are revealed between such philosophies and the knowledge of cymatic phenomena independently acquired through modern scientific research.”  

”Now it is beyond doubt that where organization is concerned, the harmonic figures of physics are in fact essentially similar to the harmonic patterns of organic nature…. In the first place, we have the certain experience that harmonic systems such as we have visualized in our experiments arise from oscillations in the form of intervals and harmonic frequencies. That is indisputable. … If biological rhythms operate as generative factors at the interval-like frequencies appropriate to them, then harmonic patterns must be necessarily forthcoming.”

I first came across the work of Hans Jenny in the mid 70s and immediately bought both volumes of his large illustrated books. They each cost £25, even in 1975, primarily because they were printed in Switzerland, which printed fantastic photographs. These are very hard to come by now but they have recently been combined into one large volume and published in the USA  but available over here in the UK for only £35.


Hans Jenny (1904-1972) was indeed a Renaissance man in every sense of the word. A medical doctor, fine artist, pianist, philosopher, historian, physical scientist and researcher, his insatiable curiosity embraced all fields of human endeavour, and his substantial talent and acumen helped him master many of them.
