Frequency guide
Listening context
207.36 Hz is the tone that Hans Cousto's cosmic-octave system assigns to Uranus, the seventh planet from the Sun and the first to be discovered with a telescope. The pitch sits close to a G-sharp in standard tuning and carries a slightly bright, angular character that listeners often describe as unusual compared with the warmer planetary tones.
Origin: the astronomy and the octave maths
Cousto's method converts a real orbital period into an audible pitch by doubling its frequency through octaves; each doubling is one octave, and enough of them lift a very slow cycle into the hearing range.
Uranus orbits the Sun once every 84.01 Earth years, so a single Uranian year is close to a long human lifetime. The planet is also a genuine oddity: it rolls around the Sun tipped almost entirely on its side, with an axial tilt of about 98 degrees, so its poles take turns facing the Sun. Cousto read the 84-year orbit as a very low frequency and doubled it through thirty-nine octaves to reach about 207.36 Hz. The tone translates that orbital rhythm into sound; it is not a noise from the planet, which lies far beyond the reach of any sound wave through the vacuum of space.
Tradition and mythology
Uranus is the odd one out in naming too: it takes its name not from Roman myth but from Ouranos, the Greek personification of the sky and father of the Titans. Because it was found only in 1781, by William Herschel, Uranus had no ancient astrological tradition; modern astrologers gave it themes that suit its surprising discovery and sideways spin. It became the planet of originality, sudden insight, experiment, and the questioning of received ways of doing things, often called the awakener. Cousto's tone gives that modern symbolism a slightly tilted reference pitch.
The discovery of Uranus was itself a quiet revolution. For all of recorded history before 1781, humanity had known only the five planets bright enough to see by eye; Herschel, a musician and amateur astronomer, doubled the known reach of the solar system overnight, and at first took the object for a comet. The planet's extreme tilt means its seasons are unlike any other: each pole spends roughly forty-two years in continuous sunlight, then forty-two in darkness. A faint set of rings and a pale blue-green colour, from methane in its atmosphere, complete the picture of a world that does almost everything differently. It is fitting that the planet of the unexpected should have arrived in our awareness as a surprise.
How listeners use it
- A clean, slightly off-centre character compared with the Sun or Jupiter tones.
- A backdrop for sketching out new ideas or first drafts of a project.
- A sense of mental openness that suits an unstructured brainstorm.
- Best in moderate sittings; the slight tilt can become tiring over long sessions.
What the evidence says
NCCIH’s overview concerns music-based interventions. Our inference is that this evidence does not establish a clinical benefit from this isolated 207.36 Hz tone. Personal enjoyment is a listening response, not a clinical measurement. Read the music research and its limits.
How to listen
- Try a short session of ten to fifteen minutes before a piece of creative work.
- Pair it with a journaling prompt about a habit you would like to question.
- Keep the volume modest so it stays a backdrop rather than a foreground voice.
- Use it under sketching, mind-mapping, or rearranging your workspace.
- Step away if the slight edge starts to feel restless rather than refreshing.

207.36 Hz Uranus: change and listening context
The Uranus tone is part of Hans Cousto's cosmic-octave system, which doubles the frequency calculated from a real orbital period through octaves until it becomes audible. Uranus takes about 84 Earth years to circle the Sun on its famously tilted axis, and the resulting reference has a bright, slightly unusual character that listeners often associate with openness and fresh thinking.
Where the symbolism comes from
In astrology Uranus is the "Great Awakener", linked with innovation, sudden change, and independence; it rules the forward-looking sign Aquarius. The planet itself was the first discovered with a telescope, by William Herschel in 1781, which is part of why modern astrologers attached themes of discovery and the unexpected to it. Western astrology ties it to societal shifts and the urge to break from old patterns.
The figure is a translation of orbital motion into sound, not a sound the planet emits, since audible waves cannot cross the near-vacuum of space. The "awakener" symbolism is a frame for the imagination, not a property of the audio, any sense of a breakthrough belongs to you and your circumstances, not the tone.
How listeners use it
- A bright, slightly out-of-the-ordinary quality that suits creative or exploratory work.
- A backdrop when you want to think freely and entertain new ideas.
- A companion to brainstorming, sketching, or writing without editing.
Many people use it as a small cue to loosen habitual thinking rather than as a wind-down sound. For more on attention and sound, see our overview of binaural beats and brain waves.
How to listen
- Try a short session of ten to fifteen minutes during active or creative work.
- Keep the volume comfortable so the tone sits alongside, not over, what you are doing.
- Pair it with one open question you would like to explore.
- Switch references if the brightness starts to feel restless rather than fresh.

What is 207.36 Hz?
207.36 Hz means 207.36 cycles per second. Cousto doubles Uranus's 84-year orbit through octaves into this tone; named for the Greek sky-god Ouranos and discovered only in 1781, the sideways-spinning planet became the modern symbol of originality and sudden insight.
