432Hz is the frequency of the Universe. The difference between 440Hz and 432Hz is only 8 cycles per second. However, this is enough of a difference to make a noticeable vibrational difference in human perception. We all have a certain vibrational frequency, not to mention that our bodies are estimated to be around 70% water, so we can probably expect that musical frequencies can alter our own vibrational state. Each expression through sound, emotion or thought has a specific frequency that influences everything around it, just as a single drop of water can create a larger ripple effect in a large body of water.

Another interesting finding is that the A=432 Hz tuning correlates with the color spectrum, while A=440 Hz is off. All frequencies in the spectrum are related in octaves, from gamma rays to subharmonics. These colors and notes are also related to our Chakras and other important energy centers. The chakras are connected to the seven rays of the solar spectrum, so the notes and frequencies we use for them should be the same.
