The Tone of Neptune

What Neptune's tone is

In the Cosmic Octave, every planet has a tone of its own, found by taking the length of its orbit and doubling its frequency, octave after octave, until it lands in a range we can hear. Neptune takes about 165 years to circle the Sun. Carried up into hearing, that very slow rhythm becomes 211.44 Hz, a soft tone a little above the G sharp below middle C.

Neptune is the planet of dreams, imagination, compassion and the sacred: where the edges blur, where you sense something larger, where art and devotion live. Its tone is often described as misty and dissolving, a sound that seems to loosen the outline of things.

Where the number comes from

The Cosmic Octave was worked out by the Swiss mathematician and musicologist Hans Cousto in the late 1970s. It isn't a mystical assignment: it's arithmetic applied to the real orbit of each planet. What people make of the tones is where the tradition begins. Sound healers pair Neptune with the third eye, and DIVINE Sound pairs it with the Solfeggio tone of 963 Hz, which tradition links with the divine and a sense of oneness.

Listening

Many people use the Neptune tone near the end of a session, to drift, or before sleep or creative work. Try it lying down in low light, eyes closed. Let the sound fill the space until you can't tell where it starts. Notice any images that come. There's nothing to hold on to: the practice is simply listening.

In your chart

Neptune plays a larger part in your life when it's prominent in your chart: close to your rising or midheaven, touching your Sun or Moon, or in Pisces, the sign it's paired with in modern astrology. DIVINE Sound builds your sound bath from your own chart, so the planets that shape you are the ones you hear.
