Pythagorias of Samos first investigated sound therapy in 600BC. Today we understand the benefits of sound therapy and many forms of the therapy exist today from Indian playing sitar music, tuning forks, chanting and singing bowls.
The belief is the different frequencies and pitches of sound bring a state of harmony to allow specific healing to occur. Most healing using sound therapy will focus on neurological disorders, tinnitus, vertigo and dizziness.
