Ancient Greeks once remarked that "geometry is frozen music". To their Egyptian teachers, sacred geometry and music were inextricably linked since the laws of the former govern the mathematical intervals that make up the notes in the western music scale- the diatonic ratios. Coincidentally, Hawkins' Euclidean theorems had also produced diatonic ratios. So for the first time, geometric theorems were linked with music and crop circles were proved to contain musical notes, which are themselves the by-product of the harmonic laws of sound frequency.
The fields themselves offered blatant clues pointing to a sound component. In 1996 a crop circle demonstrated the combination of two important figures, the 3, 4, 5 triangle and the Golden Mean, which gives us the diagram necessary to produce musical ratios (as exemplified in The Divine Proportion by H.E. Huntley).
Then, an outstanding formation at Goodwood Clatford- which had its plants bent six inches from the top - gave the proverbial nod to sound. For here was a representation of a cymatic pattern in 5000 sq. ft of barley. And it led straight to a smoking gun
In 1967, Swiss scientist Hans Jenny published the first of his painstaking studies of the vibrational affects on physical mediums such as water, plaster, oil and sand- Cymatics. By transmitting sound in the shape of a monitored frequency through these elements he was able to capture on film the exact geometric pattern that sound makes as its vibrations move through these substances. Changing the vibration altered the shape of the geometry captured in the receiving substance- a low frequency produced a simple circle encompassed by a ring, whereas a higher frequency increased the number of concentric rings around a central circle. As the frequencies rose so too did the complexity of shapes, to the point where tetrahedrons, mandalas and Pythagorean forms could be discernible. Jenny not only managed to solidify sound, he also enabled humanity to observe frozen music.
Jenny also provided a physical connection to the creation of crop circles since many of the vibrational patterns found in his photos mimicked their designs. Some were blatant imitations, such as a circle surrounded by concentric rings from the 80s, the tetrahedron at Barbury Castle in 1991, the mandalas and spider's web of 1994, even the highly structured Pythagorean-based star fractals of 1997. Other photos demonstrated the construction geometry encoded within crop circles but only visible upon dissection of overhead photographs by compass or computer.
