There are different types of sound therapy, including vibrational sound therapy, which uses special sounds that produce vibrations thought to improve brain waves.

Healing with sound is believed to date back to ancient Greece, when music was used in an attempt to cure mental disorders. Throughout history, music has been used to boost morale in military troops, help people work faster and more productively, and even ward off evil spirits by chanting. More recently, research has linked music to a number of health benefits, from boosting immune function and lowering stress levels to improving the health of premature babies.
