Standard treatments for depression include basic psychosocial support combined with antidepressant medication or psychotherapy. It has been observed, however, that only 50% of individuals respond to psychological treatment, and only 30-40% of patients achieve full remission after initial treatment with antidepressants. Music- and sound-related therapies have the potential to serve as adjuncts to, or facilitators of, medication. Several recent systematic reviews have concluded that music is an effective therapeutic tool with significant results on improving global state, symptoms, and overall functioning, and is also well-accepted by patients.
