A planet gong pitch. Paiste tunes its Uranus gong to 207.36 Hz.
How well is this supported?
Calculated from a measured value by a stated method. You can check the arithmetic. What the result means is a matter of interpretation.
This entry gives a typical pitch for an instrument. Real instruments vary.

Where this number comes from
Paiste tunes its Uranus gong to 207.36 Hz. The tuning comes from Hans Cousto's tables. Cousto took the time Uranus takes to orbit the Sun, about 84 years, and doubled its frequency 39 times, until it became a tone people can hear. Paiste names the gong by its lowest tone, G#2 at 103.68 Hz. That is the same note one octave lower, which means half the frequency.
- Step 1. Start with the length of the cycle
Uranus orbit around the Sun: 30,685.93 days.
- Step 2. Turn it into a frequency
One divided by that many seconds is 3.77 × 10⁻¹⁰ Hz. That is far too slow to hear.
- Step 3. Double it 39 times
Doubling a frequency raises it by one octave: the same note, higher. After 39 doublings it is 207.36 Hz.
- Step 4. Name the note
207.36 Hz is a G♯, in tune with standard tuning. A cent is one hundredth of the step between two neighboring piano keys. To play in tune with this tone, an instrument sets its A to 439.37 Hz instead of 440.
- Step 5. Keep doubling and the number lands in the range of light
41 more doublings give the frequency of light with a wavelength of 658 nm, which is orange. This is arithmetic. It pairs a tone with a color; it does not show that the two are connected.
The method is Hans Cousto’s. Planet gongs explained walks through it and says what it does and does not show.
What is said about it
What is said, not what was measured
Astrological tradition calls Uranus the planet of innovation and awakening. In planetary gong practice this gong is associated with sudden insight, freedom and breaking patterns.
