Dr. A. True Ott was explaining his health research into minerals, and the health effects of frequencies on this program (http://corporationnationradioarchives.wordpress.com/2014/10/09/radio-show-229-october-08-2014/) (The Corporation Nation, 8 October 2014).

He relates this subject to the fundamental Schumann resonance (approximately 8 Hz).

A website he mentioned omega432.com contains historical and technical detail from a different perspective on 432 Hz.

Also there are many YouTube videos on this subject, including examples of music in 432 Hz

It may be worth investigating this topic, considering the amount of music we listen to. From what I understand, 440 Hz was imposed on us in the mid twentieth century in the same way that many other things are imposed on us.
