440hz is currently the standred tuning for all music AKA concert pitch. Devolved by the Nazis in 1939.
I personally can tell the difference immediately between the 2. It is said by many that 440hz affects the mind and ego and 432hz affects the mind, boy and soul. I feel 432 hz fits better personally too my ears. Back in the day of Mozart, people use to bask in the sound and everyone was tuned to 432 hz. It was a a enjoyment of the soul. Something we've almost seemed to have lost.
The more people that become aware and conscious, I believe will start to notice it. So here is a song on sound cloud. One of my first of many to come. I highly encourage everyone to tune to 432hz :)
