Music therapy, the use of music for therapeutic or pedagogical purposes, has a long history, going back to ancient Egypt, the Bible and the Greeks (E.Feder and B.Feder, 1981, chap. 1). In “modern” times, scientific research methods have been applied to what the ancients knew intuitively: music has measurable physiological effects on the body and produces psychological effects on mood and personality. Listening to music produces changes in blood flow and blood pressure, changes in posture, respiratory rate, pulse rate and general activity. Listening to music also produces measurable mood changes; for example, listening to and playing music have been shown to be effective antidepressant measures.
