The Schumann Resonance – The Earth's Heartbeat
To understand the popularity behind 432 Hz, we need to first learn about the Schumann Resonance. This will ultimately explain the number’s importance.
A German physicist, Winfried Otto Schumann, documented the Schumann Resonance in 1952.
He understood that global electromagnetic resonances exist within the cavity between the Earth’s surface and the inner edge of the ionosphere.
He determined that the frequency of these electromagnetic waves is very low, ranging from 7.83 Hz to 8 Hz.
The Earth used to resonate at a steady average of 7.83 Hz, but in recent years we've seen a shift more towards an average of 8 Hz.
This frequency range is referred to as the Earth’s heartbeat, or vibration.
The Link Between 432 Hz and 8 Hz
So what's 432 Hz got to do with the Schumann Resonance of 7.83 – 8 Hz?
Well, musically speaking, the two resonate with each other.
Here's a fairly simplified explanation of how this came about, without too much math.
In 1713, a French physicist named Joseph Sauveur came upon a new concept:
Rather than tuning music at 440 Hz or other variations, he noted that by placing middle C at 256 Hz, you could create a system where each octave (or factor) of C lands on an even integer (whole number), instead of containing awkward decimals.
It is those awkward decimals he alluded to that make conventional music tuning (440 Hz) not sound as nice as music played at 432 Hz.
So, when we tune an instrument to 432 Hz, we get a C note at 256 Hz, which, due to the sympathetic resonance of the note overtones, will produce another C at exactly 8 Hz.
This frequency of 8 Hz – which is at the top end of the Theta brainwave state – is the brainwave state that makes us feel relaxed but conscious and open to intuitive learning.
Why 432 Hz Resonates with Humans
The next question is: okay, so the musical theory makes sense, but why bother tuning to 432 Hz in the first place?
Well, firstly because it actually makes more sense, from a music theory stand point. You tune to nice whole numbers and not decimals – which are awkward.
But on a more primitive and spiritual level, one would presume it optimal to play music in alignment with our planet, with nature.
We know that prolonged exposure to certain frequencies can cause us to feel adverse physical effects.
Think for a moment about all the frequencies that travel through your brain on any given day: from cell phones, Wi-Fi, 5G, radio, and microwaves.
All these devices transmit at different frequencies. These manmade inventions are constantly penetrating our brains with different frequencies.
It is no wonder that devices that emit artificial electromagnetic radiation have been linked to cancer, depression, insomnia, and even miscarriage (2, 3, 4).
Also consider the repelling frequencies of car alarms, speaker or microphone feedback and the dental drill.
Then consider natural frequencies, such as birds singing, leaves rustling, rain, an ocean breeze. Do these things bother you, or comfort you?
These everyday vibrations made by Mother Nature resonant with our being.
They have, over the centuries, inspired the creation of instruments: think of the wind whistling through a hollow tree, and then consider the creation of the flute.
It makes sense that listening to music tuned to 432 Hz (8 Hz) would make us feel more calm and balanced; because it's in our DNA. We come from the Earth. We are part of the Earth.
We've created a recording with the instrumentation tuned to 432 Hz, and a binaural beats frequency tuned to the original Schumann Resonance of 7.83 Hz.
The binaural beats encourage your brain to follow along and produce Theta brainwaves, making you feel relaxed, while the music aligns you with the frequency of Mother Earth.
