Uranus tuning fork — 207.36 Hz

207.36 Hz is the tone of Uranus, which takes 84 years to complete one orbit. Tradition gave it breakthroughs and sudden insights, after the image of Uranus in astrology.

In practice something else is more interesting: Uranus and Neptune are exactly 4.08 Hz apart. That is the theta range, and in the beats method the “Uranus + Neptune” pair is considered the main one for a state in which boundaries dissolve. Nothing needs adjusting: two real planetary frequencies produce the right rhythm on their own.

How this number is obtained

The axis is logarithmic: each doubling raises the sound by exactly one octave. The pitch goes up, the note stays the same.

Given: the period of Uranus

84.01 years = 2 651 218 560 seconds

1The frequency of the cycle itself: how many times it repeats per second

1 ÷ 2 651 218 560 = 0.000 000 000 377 19the same in short form: 3.77 × 10⁻¹⁰ Hz

A tiny number that cannot be heard: human hearing starts at about 20 Hz. But it is a real frequency, and we can keep working with it.

2Raising it into the audible range: each doubling is one octave up

0.000 000 000 377 19 × 2 = 0.000 000 000 754 371st doubling

0.000 000 000 754 37 × 2 = 0.000 000 001 508 72nd doubling

0.000 000 001 508 7 × 2 = 0.000 000 003 017 53rd doubling

⋮35 more doublings just like these

103.68 × 2 = 207.3639th doubling: now it is in the middle fork band

Or, in a single line:

0.000 000 000 377 19 × 2³⁹ = 207.36 Hz

where 2³⁹ = 549 755 813 888, the number of times the frequency has grown

The value Cousto published is 207.36 Hz. It matches.

3Which note it is

12 × log₂(207.36 ÷ 440) = −13.02semitones from A

nearest whole number: −13 = G#and that is the note

remainder: −0.02 of a semitone = −2 centshow far the tone is from the note

One hundred cents make one semitone. Planetary frequencies almost never land exactly on a note: orbits know nothing about musical tuning.

4In which tuning it would be an exact note

207.36 ÷ 2^(−13 ÷ 12) = 439.38 Hz

An ordinary piano is tuned to A = 440 Hz. Here the tone gets a tuning of its own, and for the Om tone it is exactly the much-discussed 432 Hz.

5Color: the same frequency raised all the way to light

207.36 × 2⁴¹ = 455 988 743 385 468 Hzthat is 4.56 × 10¹⁴ Hz, already visible light

299 792 458 ÷ 455 988 743 385 468 = 657 nmwavelength → orange

Divide the speed of light by the frequency and you get the wavelength. This is a model, not the measured color of a planet, but the arithmetic is exactly the same as for sound.

What tradition ascribes

Tradition

Breakthrough, awakening, freedom.

This is a system of correspondences, not the result of a measurement: controlled studies of planetary frequencies do not exist. We present the tradition because it exists and the practice is built on it — but we call it tradition.
