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 "musical pitch" in the universe, as opposed to 440 Hz, which is the standard in the music nowadays in, for example, music albums and mp3 files. This musical pitch is the standard pitch of the diapason, which is the musical note A above the middle C, scientifically named A4.
In 1939 Germany and England determined 440 Hz as the frequency of the musical pitch, after first recommendations in the 19th century. Their effort to standardize this worldwide didn't succeed for then. 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 therefore adjusted at 440 Hz nowadays, that wasn't earlier always the fact. If you find musical instruments from ancient times (for example from the old Greeks and Egyptians), 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?
1. Research shows that music in 432 Hz, in according to the majority of the music lovers, is nicer for hearing, softer, brighter and more beautiful than music in 440 Hz. But you must have a good ear for music to hear this difference. Practically the difference is more clear with quiet and classical music than with hard, loud music.
2. 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. Further there's also less noise pressure with 432 Hz. .
3. 432 Hz is more favourable for the chakras too. 440 Hz is working at the third eye chakra, "the thinking", while 432 Hz is working at the heart chakra, "the feeling". Listening to music in 432 Hz therefore accelerates the spiritual development of the music lover, although the tempo is for everyone different.
The committee 'Back to 432 Hz' wants, because of these reasons, a worldwide introduction of 432 Hz as the standard musical pitch, 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. Most musical instruments can be adjusted in principle 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.
