Sound and music consist of vibrations, the more vibrations per second, the higher the pitch. The unit for this is the Hertz, abbreviatedHz. 432Hz is the natural "musical pitch" in the universe, as opposed to 440Hz, 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 440Hz as the frequency of the musical pitch, after first recommendations in the 19th century. The United States did this already in 1936. Their effort to standardize this worldwide didn't succeed for then. But in 1953 at a congres of musicians in London, 440Hz still became the international ISO 16-standard. Many protests of (among others) French musicians, who wanted 432Hz as the standard, didn't help unfortunately. Most musical instruments are therefore adjusted at 440Hz 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 432Hz. What are the advantages of 432Hz above 440Hz? 1. Research shows that music in 432Hz, in according to the majority of the music lovers, is nicer for hearing, softer, brighter and more beautiful than music in 440Hz. 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 432Hz gives a greater clarity than 440Hz, there's less need to play music in 432Hz as loud as in 440Hz. 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 sound pressure with 432Hz, what means that at a high volume (for example at concerts) it's possible that (more) hearing damage will be prevented. This has to be researched further scientifically. 3. 432Hz is more favourable for the chakras too. 440Hz is working at the third eye chakra, "the thinking", while 432Hz is working at the heart chakra, "the feeling". Many music lovers find the latter more pleasant, especially highly sensitive people. Listening to music in 432Hz also accelerates the personal development of the music lover, although the tempo is for everyone different. The committee 'Back to 432Hz' wants, because of these reasons, a worldwide introduction of 432Hz 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 8Hz. If many people know this and also believe the qualities of 432Hz, it's to be hoped that the music industry will change the standard finally. Most musical instruments can be adjusted in principle at 432Hz 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. (c) Comité 'Terug naar 432Hz'  info@terugnaar432hz.org
