sound and music consist of vibrations, the more vibrations per second, the higher the pitch. The unit for this is the Hertz, abbreviated Hz.
432 Hz is the natural "keynote" in the universe, as opposed to 440 Hz, which is the standard in the music nowadays in, for example, music albums and mp3 files.
But in 1953 at a congres of musicians in London, 440 Hz still became the international ISO 16-standard. Many protests of (among others) French musicians, who wanted 432 Hz as the standard, didn't help unfortunately.
Most musical instruments are also adjusted at 440 Hz nowadays, that wasn't earlier always the fact. If you find musical instruments from much earlier times, and nowadays in still distant areas on Earth, these instruments are mostly adjusted at 432 Hz.
What are the advantages of 432 Hz above 440 Hz? 432 Hz is, in according to many music lovers, nicer for hearing, is softer, brighter and more beautiful than 440 Hz.
Because 432 Hz gives a greater clarity than 440 Hz, there's less need to play music in 432 Hz as loud as in 440 Hz. This means less hearing damage, as long as you put the volume not too high. It's known that, for example, 90 dB gives hearing damage after 8 hours.
432 Hz is likely more favourable for the chakras too. 440 Hz seems to work at the third eye chakra, "the thinking", while 432 Hz seems to work at the heart chakra, "the feeling". Listening to music in 432 Hz therefore could have a good influence at the spiritual development of the music lover.
The committee 'Back to 432 Hz' wants, because of these reasons, a worldwide introduction of 432 Hz as the keynote in the music, like it seems most in days gone by too.
The committee thinks it's important that at first so many people as possible get acquainted with the difference of 8 Hz. If many people know this and also believe the qualities of 432 Hz, it's to be hoped that the music industry will change the standard finally.
All musical instruments can be adjusted at 432 Hz too, although it's not so easy for every instrument.
The Dutch journalist and music lover Richard Huisken is the initiator of this committee, founded in April 2008.

I ween, in Valhalla's walls;
800 fighters through each door fare,
When to war with the Wolf they go."
