Shakespeare once said, "If music be the food of love, play on". The power of music over the human mind is enormous, and that's putting it lightly. Music therapy is the use of music for therapeutic purposes by a trained professional. The idea of using music as a healing influence dates back to the time of Plato and Aristotle. In the modern world, music for therapy came to the fore when musicians played for war veterans to cure them of physical and emotional trauma. Since many of the patients responded well, nurses and doctors began requesting the services of musicians for therapy.
