Music therapy is a therapeutic method that uses musical interaction to help people with serious mental illness to develop relationships and to address issues they may not be able to using words alone. Studies to date have examined the effects of music therapy as an add-on treatment to standard care. The results of these studies suggest that music therapy improves global state and may also improve mental state and functioning if a sufficient number of music therapy sessions are provided.
