 Researchers examined data on 421 people who participated in nine
previously completed short-term experiments testing the benefits of
music therapy on its own or added to traditional interventions for
depression.
Overall, the analysis found patients felt less depressed when music
was added to their treatment regimen, according to the analysis in
the Cochrane Library.
Music therapy also appeared to help ease anxiety and improve
functioning in depressed individuals, and it appeared just as safe
as traditional treatments.
“We can now be more confident that music therapy in fact improves
patients' symptoms and functioning, and that this finding holds
across a variety of settings, countries, types of patients, and
types of music therapy,” said senior study author Christian Gold of
Uni Research Health in Bergen, Norway.
More than 300 million people worldwide have depression, which is
projected to become the leading cause of disability by 2020, Gold
and colleagues write.
Music therapy can include passive approaches that involve listening,
active treatments that involve playing an instrument or singing or
participating in a musical performance, or some combination of these
approaches. What sets therapy apart from other musical endeavors is
that it is typically led by a person with training in counseling,
psychology or treating depression.
Even though music therapy has long been used all over the world,
research to date hasn’t offered a clear picture of its benefits,
Gold said.
The last review of music therapy published by Cochrane in 2008
didn’t offer as much evidence of benefits, Gold said. A milestone
study that came out in 2011 concluded that music could help but was
only done in one country and left many unanswered questions, he
said.
“The present review update confirms these findings and broadens
them,” Gold said by email. “We still think that more research is
needed; however, we feel that research on music therapy for
depression can now turn to more specific questions, such as
comparing different types of therapy to each other.”
Studies included in the current review ranged in duration from six
to 12 weeks. The smallest study had just 14 participants, and the
largest one included 79 people.

The total number of treatment sessions ranged from eight to 48, and
the duration of sessions varied from 20 minutes to two hours.
Only one of the studies in the analysis compared active versus
passive music therapy, and it didn’t find a difference in the
short-term severity of depression.
“The most important finding is that music therapy shows short-term
beneficial effects for people with depression when added on top of
baseline psychological or pharmacological treatment,” said Dr. Gjin
Ndrepepa, a researcher at Technical University in Munich, Germany,
who wasn’t involved in the study.
How it works isn’t clear, Ndrepepa said by email.
But modern brain imaging studies have shown that music therapy
activates regions of the brain that are involved in regulating
emotions. Joyful and sad music can have different effects, too,
Ndrepepa added.
More research is still needed to figure out what type of music
therapy works best for specific patient situations, Gold said.
“Until we have more specific research results comparing different
music therapies to each other, music therapy should be seen as one
of a variety of options,” Gold said. “It is important to have
choices because no therapy works for everyone.”
