Otto Tuners are used for relaxation as the sound vibrates into the bones for a soothing effect. 

They vibrate at a low pitch and, due to their weighted ends, the sound lasts longer
than that of regular tuning forks.

 

128 Hz (vibrations per second) - creates a deep earth tone. This deep tone resonates the bone and relaxes the tissues. When placed on the sternum, ribs and upper spine, it is especially good to relieve back tension.
