The Low OM Tuning Fork is a lower octave of the Mid OM frequency. Based on the primordial vibration or ever-sounding tone, the cosmic OM tone has a grounding connection to planet earth. Its frequency, 68.05 hz, is based on the earth’s rotation around the sun—specifically the 31st octave of the frequency of a tropical earth year (the period of time from one sun’s passage of the spring equinox till the next).
The Low OM is useful for working on the lower body due to its grounding tone. It has been shown to help reduce swelling and inflammation as well as promote bone healing. Strained muscles, tendons and ligaments may also benefit from its tone. It complements a Mid OM Tuning Fork creating a resonant octave. The Low OM, like all cosmic OM vibrations is relaxing, soothing, balancing, sedative and grounding.
Mathematician Hans Cousto calculated the Earth Year (OM) frequency in his book, The Cosmic Octave.
