What you are seeing on those Chladni plates is a standing wave, what this means is THAT PLATE has a resonance at 432 hz. Imagine a similar membrane to this plate, a drum skin, now you know that a drum skin size and tension will determine its tuning. Right? So if you hit it with a stick it will make a noise with resonances at related pitches.

A small or a tight membrane, will have a higher pitch than a large or loose membrane.
So what you are seeing in those particular Chladni plates is simply somebody trying to prove their own belief. In fact it's just THAT PLATE which vibrates with a resonance at 432. That is all.
As for the experiments of Dr Masaru Emoto and the supposed resonances of various songs. LOL. This is the guy who could talk to water, who thought water has a memory. It's a nonsense. But but but ... he's a Doctor ! He must be a respected and learned scientist of some kind.
In October of 1992, he received certification from the Open International University as a Doctor of Alternative Medicine. If you would like to become one yourself then feel free to obtain one, by email. It will cost you $242 USD though. http://ointunialtmed.net/phd-programme
If you start to believe this stuff, then I strongly suggest you take a look at your gravity bong and think deeply "am I becoming a credulous kook who believes in any fairy story which supports my fantasy lifestyle of being a modern day wizard"
All my friends who used to follow this guy feverishly and only drink water which had been sanctified through his wacko methods, they are now on antipsychotic medication. I assume this is something to do with the resonance of their bongwater.
