- 136.1 Hz is the 'OM frequency' — the tone of the Earth's year in the cosmic-octave system, the traditional tuning of Indian sitars and tanpuras, and the pitch many sound-healing instruments are built around.
- Take the Earth's orbital period, treat it as a vibration, and raise it octave by octave into hearing range: you land on 136.
- Most OM tuning forks, singing bowls marked 'OM', and chakra instruments for the heart center are tuned to 136.1 Hz.
- The derivation is beautiful and checkable: one Earth year is 365.
- Hear 136.1 Hz instantly in our free tone generator, or listen inside full 432 Hz-tuned compositions

What Is 136.1 Hz — the OM Frequency?
136.1 Hz is the 'OM frequency' — the tone of the Earth's year in the cosmic-octave system, the traditional tuning of Indian sitars and tanpuras, and the pitch many sound-healing instruments are built around.
136.1 Hz Frequency Benefits & Uses
Take the Earth's orbital period, treat it as a vibration, and raise it octave by octave into hearing range: you land on 136.1 Hz. That calculation (Hans Cousto's 'cosmic octave') matched what Indian classical music had done for centuries — tuning to the tone used for chanting OM. It is the closest thing sound healing has to a home key.
Most OM tuning forks, singing bowls marked 'OM', and chakra instruments for the heart center are tuned to 136.1 Hz.
The Science, Honestly
The derivation is beautiful and checkable: one Earth year is 365.24 days; convert to seconds, invert to a frequency, and raise it 32 octaves (doubling each time) and you arrive at 136.1 Hz. Hans Cousto published the method in 1978 as 'the cosmic octave'. Whether an orbital rhythm means anything to a nervous system is a philosophical question — but the tone's independent role in Indian classical tuning gives it a lineage no other calculated frequency has.
136.1 Hz and Its Neighbors
136.1 Hz is to chant what 432 Hz is to music: a 'natural tuning' claim with real tradition behind it. They coexist happily — our catalog is composed at 432 Hz, and 136.1 Hz (roughly C#3 in that world) sits consonantly inside it. For OM work use 136.1; for everything-music, 432.
The Best Moments to Use 136.1 Hz
OM chanting — three rounds aloud over the tone, then silent repetition; this is its home use.
Savasana and yoga nidra — the traditional accompaniment pitch for deep rest at the end of practice.
Heart-centered meditation — in Indian tradition this pitch belongs to the heart; pair with slow breath at the sternum.
Hear 136.1 Hz Right Now
Play the pure tone free in our tone generator — set it to 136.1 Hz — or the full solfeggio generator. Pure tones show you the frequency; composed music lets you actually rest inside it, which is where the benefits live. Our playlist below is tuned for exactly that.
How to Use It
1. Pick one intention. 136.1 Hz works best attached to a single, repeated practice — the association is the active ingredient.
2. Keep it low and long. Volume just above a whisper, 10–20 minutes, eyes closed if you can. Headphones deepen immersion; speakers let the body feel the lower tones.
3. Repeat daily. Nervous systems learn by repetition; one consistent week beats one long Sunday.
Frequency music supports rest and wellbeing — it is not medical treatment. For ongoing health concerns, please talk to a healthcare professional.
Frequently Asked Questions
Why is 136.1 Hz called the OM frequency?
Because raising the Earth-year rhythm into the audible range octave by octave yields 136.1 Hz, and Indian classical tradition independently tunes chant accompaniment near the same pitch. Chant OM over the tone and you'll feel why it stuck.
What musical note is 136.1 Hz?
Approximately C#3 — which is why 'OM tuning forks' are sold as C#. In Indian classical music the tanpura's sadja (root) is traditionally set near this pitch for chant accompaniment.
Is it better to listen to 136.1 Hz as a pure tone or as music?
Pure tones are for tasting the frequency; music built around it is for practice. Compositions hold attention and pace the breath, which is what produces the felt benefits. Start with the tone generator, settle into the playlist.
How long until I feel anything?
The physiological part — slower breath, lower arousal — begins within minutes of any calm, steady sound. The deeper associations build over one to two weeks of consistent daily practice.
