Hahaha, i've been surfing the web for a few months searching for 432hz stuff, there is some stuff on youtube (432hz search), but most of the websites have stuff like that 09_Namaste_Prana stuff..., after a while i get sick of hearing it since it's sorta dark ambient music >: doesn't that just ruin the point for 432hz, lol?

What you are seeing is a speaker mounted to the bottum of a steel
plate and then sand is poured on it while a note is produced to make the plate vibrate and the note is constantly raising in pitch ...ok?
now when you see a perfect shape and if you were to find out
excactly what that note was that is causing that perfect geometic
shape? then you would find out (which is what I did)
that this note (or notes) are all based on the resonant frequency of
a-432...[edit on 20-12-2007 by Maya432]
Equal Temperament Scale - The mathematical basis for pitch.
Modern keyboards are tuned to a scale known as the Equal Temperament Scale. This is a compromise between playing something that sounds musically correct and the ability to play in any key. When you sing a major scale, you subconsciously use a scale called the Just Intonation Scale. This is the scale that sounds right, at least to people brought up on Western music. Unfortunately there are small peculiarities of the Just Intonation Scale which make it unsuitable for keyboards, which need to able to play in different keys.
For example, when you sing do re mi starting on C, you get C, D, E. When you start on D, you get D, E, F#. The E note produced by these two sequences is not the same. The difference between them is only very slight, but it is audible to a keen ear. When tuning the keyboard, which note should the tuner use?
The Equal Temperament Scale was devised about 200 years ago to overcome these difficulties and has been used ever since.
This entry will show the mathematical basis for the Just Intonation Scale, show the problems it introduces for keyboards, some of the other scales which attempt to overcome this and then show the Equal Temperament scale, which is the accepted solution to the problems.
The mathematical basis for pitch
The pitch of a note is given scientifically by a number called its frequency. Sound is a regular vibration of the air. Frequency is the number of vibrations per second. The more vibrations per second, the higher the frequency, the higher the pitch. The unit of frequency is hertz, abbreviated Hz. The note A, which is used for tuning orchestras, is 440 Hz, which means 440 vibrations per second.
