"If you want to find the secrets of the universe, think in terms of energy, frequency and vibration" - Nikola Tesla
With their revolution around the sun, each planet emits a specific frequency. We are so immersed in the environment we live that we are not aware of those strong sounds. However, if we become aware of them, we can figure out the cosmic symphony in which we are immersed.
First, we will examine the classification used for binaural beats, which takes into account higher harmonics.
Note (440 Hz)
Note (432 Hz)
D3 (146.83 Hz)
D3 (144.16 Hz)
F#3 (185 Hz)
F#3 (181.63 Hz)
D3 (146.83 Hz)
D3 (144.16 Hz)
B2 (123.47 Hz)
C3 (128.43 Hz)
A3 (220 Hz)
A3 (216 Hz)
C#3 (138.59 Hz)
C#3 (136.07 Hz)
G#3 (207.65 Hz)
A3 (216 Hz)
A4 (440 Hz)
A4 (432 Hz)
As we can see, the cosmic chord is a nineth: B-D-F#-A-C#. The only planed that is somewhat out of tune is the Moon, being a G#3, but we can say that it is largely assimilated by A3, as it tends to it.
In another interpretation, we can thing the cosmic chord to be an eleventh: G#-B-D-F#-A-C#. We also plotted the frequencies when the scale was not tuned at 440 Hz, but at 432 Hz (also called concert pitch), till '800. In this case, we can notice that the chord is a seventh, and therefore less dissonant: D-F#-A-C/C#. 432 times 432 = 186624. Considering that the classic speed of light is 186400 miles/second, there is only a small difference of .001201.
From the scheme above, we can relate planets to notes. As we have two D notes and Saturn is the farthest planet, we can assign E to it, which is the only missing note. Thus, we obtain the following table.
If we want to establish a relation between semitones and zodiacal signs, we can use the traditional dominant planet associated to a sign to infer the correct notes. We will obtain the following table.
Nowadays, the scale is one semitone higher than in the past (it was changed somewhen in the nineteenth century). We may build the tables above shifted one semitone below, but the underlying reasoning will not change.
Now, we will analyze the harmony of the cosmos according to physics. Many authors, such as Gustav Holst in Planets, preferred to describe the planets musically according to their mythological representation, instead of using the real planeray frequencies. Giorgio Costantini was one of the few investigating the real tones of planets.
The exact frequency of each planet can be calculated mathematically from its periods of rotation around the sun and corresponds to the opposite of the rotational frequency.
F is the frequency of the oscillation of the planet - i.e. the rotation around the Sun
n(semit) is the musical interval in semitones starting from C1 (32.7031956626 Hz)
The rotation frequency of the planet is obtained by the opposite of the period of rotation around the sun, calculated in seconds. Thus, we obtain the following table.
A visual representation of the planets and their foundamental tone is as following.
Now, we will examine the notes played by the planets in order according to their distance from the Sun, arranged in a single octave.
Without taking into accout the furthest planets (Uranus, Neptune, and Pluto), which have no representation in the musical scale, we can see that the chord is clearly D-F#-A-C#. The only major difference with the binaural representation is that the Earth is no longer a B, but a C#. All the other planets retain their pitch. We may wonder which calculation is the most correct. The answer is certainly the physical representation. Therefore, the solar system relies on the fundamental frequencies of Mars and Saturn. However, for the theoretical need to assign each planet to a different note, we will assume that our first table is correct.
The fact that the planets closer to the Sun produce the higher and most dissonant frequencies is explained by the fact that their orbit is smaller. Therefore, they can only produce higher sounds. The distant planets, instead, have a wide orbit and can take all the time to produce the fundamental and consonant tones.
We also may take into account the frequency produced by the magnetism of the Earth, which is 7.83 Hz. This corresponds broadly to a B-2 (7.72 Hz). Global electromagnetic resonances excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere are called Schumann resonances and take place in multiples of the fundamental frequency - 14.3 (A#-1, 14.57), 20.8 (E0, 20.6 Hz), 27.3 (A0, 27.5 Hz), and 33.8 Hz (C#1, 34.65 Hz). We are likely to be more impacted by this frequency than that produced by the Earth revolving around the Sun.
In this case, according to our first table, the Earth would have the lowest frequency, being exactly the fundamental of the chord. Therefore, it would be the center of the entire Creation and all other planets would be just subservient to it - i.e. they are its harmonics.
