The 432 Hz tuning explained…

There is a frequency hype going on for some time, which is rooted in a total misunderstanding of the meaning of “tuning”.

You can read all over the internet articles about “healing” frequencies or frequencies, which are supposed to activate chakras, pineal gland and even god sounds. There are countless videos on YouTube promising all sorts of advantages by listening to their mystical frequencies.

432 Hz is one of these celebrated tuning frequencies and they say it would be an ancient tuning or even the vibration of the universe.
This is all nonsense and can be very easily explained to anybody.

Meaning of Tuning

First of all, tuning means we bring the keys of a musical scale in a harmonic row. The tuning is defined as an international standard as being an A at 440Hz.
Most instruments you can buy are tuned to this standard and this is very important to have a common standard because if you would hear a band with every instrument being tuned differently, it would sound terrible “out of tune”.

So, what is the meaning of a different tuning besides the standard 440 Hz?
If you have a random frequency and you would like to tune for example a guitar to this frequency, you must know the so-called “master tuning” and there are simple calculations, how to find out this master tuning.

In the case of the 432 Hz tuning, there is a tone frequency where this tuning comes from and this frequency is the 32nd octave of the Earth Year orbit around the sun. By the use of the octave (multiply by 2) we can translate any recurring event into the audible range of human hearing.
The Earth Year frequency in the 32nd octave is a C# at 136.102 Hz.
If you want to tune now the mentioned guitar to this C#, the resulting tuning frequency is 432.098 Hz.

The natural law of the Cosmic Octave calculation was discovered in 1978 by the Swiss mathematician and musicologist Hans Cousto as the link between different kinds of periodically recurring natural phenomena, such as the planet or moon orbits, the weather, colour (light waves), rhythms and tones.

For example the first-ever Cosmic Octave calculation.

The octave-tone of the rotation of Earth
Earth Rotation Period

The period of the rotation of Earth around its own axis when the Sun is high in the south until it is high again the next day.
1 day (24 hours . 60 minutes . 60 seconds = 86 400 seconds).

Earth Rotation Frequency

1 : 86 400 seconds = 0.000 011 574 Hz
(Hz = Hertz = cycle per second)

Earth Rotation Frequency

0.000 011 574 Hz x 224 = 194.18 Hz
(224 means 24-fold doubling).

These “mystical” frequencies are often a result of numerologist coming up with an interesting number and they add a Hz (Hertz) behind this number. It’s like putting a label “BANANA” on an apple.
If one wants just to play around with numbers and randomly experience a number as a frequency than there is nothing wrong with that. It is wrong, if this meaningless number suddenly gets an interpretation and artificial meanings, so a fake myth can be started.

To experience a natural frequency by tuning an instrument to it is a wonderful and interesting thing to do. There is no need for myths and pseudo-spiritual nonsense, so this frequency is becoming a holy grail of some sort.

It is beautiful enough to be the audible translation of our planet’s movement around the sun. Of course, we can translate any recurring events into audible frequencies and find their accurate tunings.

Nothing mystical and simple mathematics.

Historical facts

There are many articles to find on the internet and mostly they don’t include the final resolving information, about the real origin and meaning of the 432 Hz tuning.

Following article is a very comprehensive collection of historical facts and it debunks the myth pretty well, but the author of this article missed to mention the resolving truth about the origin of this tuning, which triggered me to write this article here.
