It is said that when we listen to intervals produced by the quartz crystal tuning forks we stimulate our vestibular nerves. The vestibular system is the basis of our sense of space, proportion and balance. When we induce a Stillpoint with tuning forks, it is hypothesized that the walls of the ventricles change their physical proportions to reflect the radio of applied interval. The new proportion is optimal for secretion of cerebro-spinal fluid(CSF) and balance of the intracranial dural membrane. This in turn harmonically organizes the motion of the individual cranial bones with the sacrum and the sound of the central nervous system.
Not the same as the quartz crystal tuning forks, Otto Tuning Forks are traditional kind of tuning forks made of metal. They have a weighted end which could help the sound continues longer than that of regular tuning forks. They vibrate at a low pitch and usually be tuned to frequencies of 32, 64, and 128cps.The Otto Tuner 128cps is especially effective when placed on the ribheads, thoracic vertebrae, sternum and illiums. The 64cps Otto Tuners is very effective when placed on lower lumbar vertebrae, sacrum and coccyx, helping the centre which controls the balance between the sympathetic and parasympathetic nervous systems.
