432 & CYMATICS
Cymatics is the study of visible sound and vibration. 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. [ Read More ] ►
Why is this of importance? Well, we do know that sound has an effect on how we feel. Not just emotional, but physically as well. It is there for interesting to see what effect particular tones (frequencies) have on matter.
In the video below on the left you see a Cymatic experiment with various tones (frequencies), both when A4=432Hz is used as Concert Pitch, as well as A4=440Hz is used. The video on the right displays various tones (fequencies) related to (or very close to) tone frequencies in 432 Tuning generated with the Software Tonoscope*.
The thickness and type of metal used, as well as the size of the grains are of influence in the relationship of frequency and pattern. If a different kind of metal is used and/or a plate of different size and thickness and/or another type of "sand", the same frequency might create different patterns or fail to generate a proper pattern.
The video below where they compare 432Hz with 440Hz is thus NOT PROOF of 432Hz being "better", it just tells us that that particular "setup" of plate and "sand" used works better with 432Hz-related frequencies then it does with 440Hz-related frequencies.
On the website of the Software Tonoscope the "Ancient Solfeggio Frequencies" concept is supported/endorsed. I do NOT support that concept as you might have read in my blog article Myth: "The Ancient Solfeggio Frequencies".
