Music therapy is an established healthcare profession that uses music to address physical, emotional, cognitive, and social needs. Music therapists use music to work on non-music goals like promoting wellness, managing stress, alleviating pain, and improving communication. The earliest writings about music as a healing influence date back to Aristotle and Plato. Modern music therapy began after World War I and II when musicians played for veterans suffering physical and emotional trauma, showing notable responses. This led to the development of music therapy as a college discipline and profession. Music therapists now work in various settings helping a wide range of populations.
