The finding that music therapy offers a real clinical benefit to depression
sufferers comes from a review by the Cochrane Collaboration, a not-for-profit
group that reviews health care issues. Although there aren’t many credible
studies of music therapy for depression, the reviewers found five randomized
trials that studied the effects of music therapy. Some studies looked at the
effects of providing music therapy to patients who were receiving drug treatment
for depression. Others compared music therapy to traditional talk therapy. In
four out of five of the trials, music therapy worked better at easing depression
symptoms than therapies that did not employ music, the researchers found.
