Music therapy emerged as a profession in the 20th century after World War I and World War II. Both amateur and professional musicians attended veterans’ hospitals to play for the veterans who had suffered physical and emotional trauma. The impact of the music on the patients’ physical and emotional responses saw the doctors and nurses requesting to hire the musicians. It became apparent that the hospital musicians required training before starting, and thus ensued the beginning of music therapy education. Music therapy is administered by trained music therapists. A music therapist evaluates each clients’ unique needs. They ascertain a client’s musical preferences and devises a treatment plan that is customized for the individual. Music therapists are part of a multi-disciplinary team, working with other professionals to ensure treatment also works for the client to achieve their goals. For example, if a person is working on strengthening and movement in order to address physical limitations, a music therapist could introduce dance into their treatment plan. Music grabs our attention and distracts us from stimuli that may lead to negative experiences, such as worry, pain, anxiety, and so on. This may also explain the anxiety and pain-reducing effects of listening to music during medical procedures. Moreover, music can regulate the activity of brain regions that are involved in the initiation, generation, maintenance, termination, and modulation of emotions. Music is related to memory processes. It is also involved in the analysis of musical syntax and musical meaning.
