Almost all of the music you hear on a day-to-day basis – whether in your car on the way to work or playing over the speakers at a local restaurant – is tuned to 440 Hz. It’s the international standard tuning and has been since the mid-1900s.

Yet, when we change our tuning for A to 432 Hz, though it’s only a difference of 8 cycles per second, there’s a noticeable shift in our consciousness and even our bodies.

In fact, a 2016 study by the American Society of Endodontists found that patients who listened to 432 Hz music before, during, and after root canal operations experienced less anxiety. And this soothing of the “nerves” led to an improvement in associated vital signs, including lower systolic blood pressure, diastolic blood pressure, and heart rate.

Results:Direct contrasts between patients listening or not listening to music showed that all the measured vital signs decreased considering the overall period (during and after the canal therapy) in the group of patients listening to music (P < .05).

Conclusions:This study shows the effects of music therapy on vital values and on subjective perception of anxiety during endodontic therapy. The soothing effects of sounds and musical frequencies make this union an extraordinary tool of synergistic care. Music therapy is a valid non-pharmacologic adjuvant to anxiety perception in endodontic therapies.

Now, if 432 Hz can have that effect on people in the middle of dental surgery, imagine how it could help our daily lives, which are hopefully a little less stressful than a root canal.

## The Significance of 8 Hz in 432 Hz Music

Okay, so remember that the modern day music tuning standard is set to A = 440 Hz. But we, among many other musicians and scientists advocate that it should be A = 432 Hz.

Well, it turns out that the additional 8 Hz difference between 440 Hz and 432 Hz is a lot more significant than it would seem at first glance.

In fact, 8 Hz is at the root of 432 Hz, literally (in terms of music).

If we start at 8 Hz, then raise the pitch by five octaves, we come to 256 Hz. With C at 256 Hz, we find A at 432 Hz, also known as “Verdi’s A”, which we explore in greater detail here. In short, Giuseppe Fortunino Francesco Verdi was an Italian opera composer.

On the other hand, with A at 440 Hz, we are left with C at 261.656 Hz. The math is clearly a little off there.

That’s why A at 432 Hz is referred to as “scientific tuning”. Thus it has been promoted by physicists like Joseph Felix Savart and Joseph Sauveur, and by scientists like Bartolomeo Grassi Landi.

When music is played at this tuning, it also resonates with 8 Hz – which is, again, the pulse of our planet.

If we tune with the Twelve Fifths Tuning suggested by classical pianist and tuner Maria Renold, and musical mathematician Grammateus – which has natural intervals and allows for an increased resonance – as opposed to the modern Equal Temperament (the adjustment of intervals in tuning a piano or other musical instrument so as to fit the scale for use in different keys), we find even greater mathematical and geometric synergy in the 432 Hz scale.

Maria Renold (1917-2003) Discovered a new method of tuning the piano, closer to the tuning of stringed instruments, arriving at the concert pitch of a1 = 432 Hz. First published in German in 1985, her book has become a modern classic of musical research.

### 8 Hz and the Heartbeat of the Planet

8 Hz is a special number for many reasons, not least because it coincides with the Schumann resonance.

In 1952, the physicist Winfried Otto Schumann discovered that the electromagnetic waves that exist in the space between Earth’s surface and its ionosphere resonate at a frequency between 7.86 and 8 Hz. That makes 8 Hz, in essence, the “heartbeat” of our planet.

That’s not the only place 8 Hz is influential.

Scientist and medical doctor, Dr. Andrija Puharich, studied healers from different places, cultures, and faiths around the world and found that their brain waves resonated at 8 Hz. And even their hands, when placed in water, vibrated at 8 Hz.

In fact, Dr. Puharich claims to have used the 8 Hz frequency to cure 27 organic diseases during his career, though his skeptics would argue against this on account of his credulous personality.

This brain wave frequency of 8 Hz is also the straddle between the Alpha and Theta frequency ranges, and is realized during meditation, Tai Chi, and when the two hemispheres of our brain are working at peak synchronization.

Our DNA replicates at a frequency of 8 Hz, and it’s also the nuclear magnetic resonance of hydrogen atoms, as noted by renowned musician and writer Ananda Bosman, which form one of the basic building blocks of living creatures and the universe.

A study by the HeartMath Institute even found that when our heart is in a state of compassion, it beats at 8 Hz, as measured by an electrocardiogram (or EKG).

## 432 Hz & Links to Ancient Geometry

What do Stone Henge and the Pyramids of Giza have in common?

Other than being popular tourist attractions and ancient monuments that we don’t quite understand, they both have a geometric relation to 432, as do many other such sites, like Sri Yantra.

As Graham Hancock points out in his book The Message of the Sphinx, the dimensions of the Great Pyramid and the dimensions of earth are connected at a scale of 1:43,200.

If we multiply its height of 481.3949 feet by 43,200 and then divide by 5,280 (the number of feet in a mile), we get 3,938.685.

That’s just 11 miles short of the radius of the earth, as measured between its poles, of 3,949.

If we multiply the perimeter of the Great Pyramid’s base, which is 3,023.16 feet, by 43,200 and then divide by 5,280 again, we get 24,734.94 miles.

That’s just 170 miles short of the circumference of the Earth, as measured around the equator.

Now, keep in mind that the radius and circumference of Earth, as we know it today, is based on the most advanced methods of measurement that we have, whereas the Pyramids were built thousands of years ago. That they were off by just a fraction of a percent is nothing short of incredible.

How did these ancient builders know discover these measurements, and why did they base the Great Pyramid’s dimensions on multiples of 432?

We see this same connection in Stone Henge.

First, let’s point out that 25,920 years is how long a complete cycle of the equinoxes takes. It’s sometimes called the Great Precessional Year or a Platonic Year. This number will be important to the relation between Stone Henge and 432.

For instance, there are several sets of stones arranged in circles of a full 360 degrees. The second circle is made up of 60 stones and represents a full cycle of 25,920 years. Divide 25,920 by 60 and what do we get? 432.

Divide 60 by 10 and we get 6. Divide 25,920 by 6 and we have 4,320.

Of course, 432 is not the only number that’s significant to the geometries of these ancient sites, but it’s one that we see again and again.

Fulcanelli, the French alchemist and author of Le Mystère des Cathédrales, even pointed out 432’s significance in relation to 25,920 in the orbit of Saturn:

Saturn, because it is at the greatest distance from the sun of all the visible planets, has the longest ‘year’, taking a little less than 30 years to complete one circuit of the zodiac. This makes it the best precessional timekeeper of all the planets.

Saturn completes one precessional Great Year of 25,920 years every 864 of its ‘years’, a half cycle every 432 of its ‘years’, a quarter cycle every 216 of its ‘years’, and an eighth of a cycle every 108 of its ‘years’.

It’s one of the key numbers in sacred geometry and resonates with the Golden Ratio.

We say two numbers fall into golden ratio when their ratio to each other is the same as the ratio between the sum of both numbers and the larger number. In other words, a / b is equal to a + b / a.

This ratio is represented by the Greek letter phi or ϕ.

Phi and the golden ratio are found all throughout nature, art, architecture, and music and are known for being aesthetically pleasing. But they also have sacred functionality. For instance, we find phi both in the spiral of our inner ear or cochlea, as well as in the spiral of the DNA double helix.

Another example of 432’s geometric significance come from John Stuart Reid’s experiments with his CymaScope. This device uses vibration to form geometric shapes in both liquid and solid mediums.

John Stuart Reid had this to say about his experiments:

432 Hertz pops out as a triangle, every time we image it. We thought there was something wrong with the CymaScope, but after trying for more than an hour we concluded that the number 3 was somehow universally connected to 432 Hertz.”

## 432 Hz & Links to Ancient History

432 pops up in many places of well-known history.

For instance, in the Bible, we can use the ages of the ten patriarchs between Adam and Noah, along with Noah’s age at the time of the Great Flood, to find that the flood came after 1,656 years.

That’s 86,400 weeks – and half that number is 43,200.

Meanwhile, Babylonian accounts place their own history of the flood at 432,000 years. Again, 432.

As for 432 Hz tuning, it’s thought to have been used by the ancient Egyptians; the Greek God of music, Orpheus; Mozart, Verdi, and Tibetan monks. More on that here.

What did all of these people, from the architects of the Great Pyramid to the great classical composers, know about 432 that we don’t?

And why aren’t we still using 432 Hz today as our musical tuning standard?

As mentioned at the beginning of this article, 432 Hz was shown to reduce anxiety and led to an improvement in associated vital signs, including lower systolic blood pressure, diastolic blood pressure and heart rate in root canal treatment patients.

Maybe your life could benefit from the psychological and physiological healing found in the secret science of 432 Hz.

The question is, why would you not listen to 432 Hz music?
