The Mid OM Tuning Fork is widely considered the classic OM frequency. Based on the primordial vibration or ever-sounding tone, the cosmic OM tone has a grounding connection to planet earth. Its frequency, 136.1 hz, is based on the earth’s rotation around the sun—specifically the 32nd 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 Mid OM is useful for working on the upper body on or around the heart chakra and works wonderfully as a universal or general purpose healing tool. It has been shown to help reduce swelling and inflammation and ease pain. The OM vibration is calming, grounding and energizing. Use it to relieve body tension, access chi and the body’s energetic pathways, assist in meditation, remove disharmony from the body, and restore a sense of well-being.
Use on tight and tired muscles, to enhance deep breathing and promote healing. Use to alleviate symptoms from repetitive stress injuries, tendonitis, tension headaches, and clenching related to TMJ. It also works well combined with a Low OM tuning fork creating a resonant octave. The Mid OM, like all cosmic OM vibrations is relaxing, soothing, balancing, sedative and grounding.
The cosmic OM frequency was calculated by mathematician Hans Cousto.
