A=440Hz and A=432Hz Frequency

In modern history in particular, there has been what Dr. Len Horowitz has referred to as the strategic “militarization” of music. This happened in 1939 when the tuning of the note ‘A above Middle C’ to 440 Hz was adopted in the world of music. In 1910 an earlier push to the same change was met with limited success. Three decades later, the British Standards Institute adopted the A=440 Hz standard. This was the year that A=440 became the international standard.

The American Federation of Musicians had already accepted the A 440 as standard pitch in 1917, and the U.S. government followed suit in 1920. One must surely ask why it is said that Nazi propaganda minister, Joseph Goebbels, argued for this odd intrusion into musical creativity.

It is interesting, also, to note that in October 1953, despite the British and Nazi push for the arbitrary A=440 standard (which is “disharmonious”), a referendum of 23,000 French musicians voted overwhelmingly in favor of A=432 Hz. Many, many musicians, through recent centuries have expressed their strong preference for the A=432 reference pitch.

“This [A=432 Hz] tuning was unanimously approved at the Congress of Italian musicians in 1881 and recommended by the physicists Joseph Sauveur and Felix Savart as well as by the Italian scientist Bartolomeo Grassi Landi.”

Interestingly, the difference between 440 and 741 Hz is known in musicology as the Devil’s Interval.

“Music based on C=128 Hz (C note in concert A=432 Hz) will support humanity on its way towards spiritual freedom. The inner ear of the human being is built on C=128 Hz.”

A=432 is bio-neutral at worst, and is widely considered bio-energetically enhancing or healing if employed intentionally. Music at 432 Hz is certainly relaxing and is widely associated with healing. Many people also appear to endorse the view that, while A=440 music is more exciting (or aggressive).
