432hz and why?

There is a reason the standard tuning of music is set to 440hz for ‘A’ above middle C. There is a lot of information on the internet about it. It could be a huge conspiracy but I’ll leave that up to you. I have downloaded 432player from Google play on my phone and I find playing it through that player, the whole ambience of the music changes and everything appears to be more peaceful.

Here is something I got from the web.

Lots of websites claim that 432 Hz is a “universal” frequency. In any case, 432 is an interesting number for several reasons.

It is the sum of four consecutive primes: 103 + 107 + 109 + 113. It is exactly three gross—a “gross” was a traditional unit of measurement of 144, or 12 squared. An equilateral triangle whose area and perimeter are equal has a square root of 432. For this reason and many more, multiple people have dedicated themselves to spreading the word about the pros of switching to the 432 Hz system.

If I had to recommend one article to look further into this subject, it would be this one. The author does an amazing job of looking at the argument with an objective and unbiased view, and goes into great depth about the history of 432 Hz and its supposed advantages over 440.

You are welcome to click that link – I just did. The change happened pretty much everywhere, though I know the New York Symphony Orchestra was against the change but for some reason most other people went along with it. Why?

There is a staggering amount of information out there on the ideal frequency for A₄ (that’s the A note above middle C). You’ve probably heard of the debate over 432 Hz vs 440 Hz but don’t exactly know what it’s about. Many of us in the world of sound design are especially likely to encounter websites and videos touting the healing power of 432 Hz.

There is a growing trend among YouTube channels posting re-tuned music in which A₄ is set to 432 Hz instead of the standard 440 Hz. You might have already stumbled upon a plethora of unsubstantiated claims and conspiracy theories and wondered, could any of this be true? Or even, am I going to have to re-tune my full back-catalog?

In order to get to the bottom of the controversy, I have gone back to the very beginning of tuning standardization and traced its lineage up to the present day. I have searched far and wide for evidence of a deeper meaning to tuning. Having gone down the rabbit hole myself, I will share my findings with you so that you won’t have to.

Hz is the abbreviation for Hertz, which is a measurement of frequency named after Heinrich Rudolf Hertz, the first person to provide conclusive proof of electromagnetic waves.

Sound as we perceive it is the result of pressure waves hitting our ears. Pitch varies based on the frequency of those pressure waves, so the most specific way of discussing pitch is by naming exact frequencies in Hertz.

However what is most specific is rarely the most efficient, so pitch is more frequently coded in terms of the letter-names that pre-date the measurement of pitch in Hertz. The common practice ever since the late nineteenth century is to tune one pitch to a specific frequency, typically A₄ to 440 Hz, and tune the rest of the instruments relative to that A. This is where the controversy begins.

If all music were written and notated in specific frequencies, there could be no debate as to how the pitches of a piece were meant to be played. So if a composer preferred 432 over 440, they could easily write it that way.
