The Mid Ohm tone
This tuning fork is tuned to 136.10 hertz, which we call the Mid Ohm. The syllable Ohm is the primordial vibration of the universe in the Sanskrit tradition, and it appears in many meditation practices. 136.10 hertz is one of the most widely used frequencies in sound therapy, and we recommend it to you for finding inner stillness.
Everyday uses
You can play this fork at the beginning of a meditation to draw your attention to the breath. In a therapist's session, holding it above the chest creates a calming vibration at the heart level. Many users also choose it for a simple sound bath without any musical accompaniment, because the 136.10 hertz tone stands beautifully on its own.
Material, size and packaging
The fork is made of light, polished aluminium, measures 27 centimetres in length and weighs 108 grams. The tuning accuracy is within ±0.25 percent, so the desired tone remains reliable for many years. A simple paper sleeve accompanies the fork, making it easy for you to take it home and store it on a shelf.
Chakra tradition
The 136.10 hertz tone is linked to the heart, the fourth of the seven main chakras. Its colour is blue-green, and it supports the quality of love and acceptance. Those who work with this fork often report feeling emotionally more open after a practice. The Mid Ohm therefore fits well into home rituals and into group sessions alike.
Care and longevity
After use, wipe the fork with a soft, dry cloth and return it to its paper sleeve. Avoid knocking it against metal surfaces. Scratching does not disturb the fine shades of the sound but keeps the appearance tidy. You will continue to enjoy the clear Ohm tone year after year.
