The therapeutic power of sound and movement has been used by different civilizations for thousands of years as a way of treatment. All of these techniques, whether they are based on mantras, such as those used by the Hindus and Icaros, or on medicine melodies, such as those used by various Indigenous peoples of Central and South America, or on Pythagoras' use of interval and frequency, have the same goal: to move us from a state of imbalance to a state of equilibrium.
