Background
Music Therapy
Music therapy is a health profession in which the therapist combines musical
interventions with a supporting relationship and seeks to improve the well-being of his or
her clients (http://www.musictherapy.org/). There are numerous goals musical therapy
can seek to accomplish, namely the management of pain, reduction of stress and
anxiety, alleviation of depression, treatment of respiratory problems, exercising of joints
and limbs, provision of control and self expression, and general promotion of good
health (Bailey, 1986; http://www.musictherapy.org/). The most common treatment
methods of music therapy are listening to music, singing, dancing, and creating music
(http://www.musictherapy.org/). The relief of pain is a primary focus of music therapy,
and numerous studies have proven it to be effective for alleviating acute pain (Bailey,
1986; Locsin, 1981; Maslar, 1986; Melzack, Weisz, &
Sprague, 1963; Michel & Chesky, 1995;
http://www.musictherapy.org/).
Pain
There are two different kinds of pain: acute and
chronic. Acute pain is sudden but temporary pain,

whereas chronic pain endures for a long time, even years. Pain is a signal of suffering in
one or multiple domains (physical, emotional, etc.) and its experience is highly
subjective (Maslar, 1986). How intensely pain is experienced and the level it can be
tolerated at depends on several factors. Expectations of pain levels, suggestion of how
well the treatment will work, mood of the patient (especially the presence of anxiety or
stress), amount of focus on the pain, and intensiveness and duration of the pain, as well
as early childhood experiences and culture can all impact how an individual encounters
pain (Locsin, 1981; Maslar, 1986; Melzack, Weisz, & Sprague). Initially, the pain is
fought naturally by the body’s release of endorphins, a type of neurotransmitter. If the
pain persists, it is typically treated with pain medication, but it can
also be treated by alternative techniques, which is where music
therapy comes into play (Maslar, 1986).
Music Therapy and Pain Management
Goals and Methods
Music therapy is generally used to reduce pain when medication does not
provide adequate relief, in which case the therapy is combined with drug use. Another
reason for using music is when pain medications cause serious side effects in a patient
and so cannot be used (http://www.musictherapy.org/). When music therapy is
employed for pain management, its goals are to increase the patient’s comfort, wellbeing, and feeling of control over pain (Bailey, 1986; Melzack, Weisz, Sprague, 1963;
http://www.musictherapy.org/). The aforementioned methods of music therapy, with the
exception of dancing, can all be applied when the therapy’s focus is pain, and which

method is chosen depends on the patient’s needs, experience
with music, and coping abilities. Regardless of the method
chosen, communication between the therapist and the patient
is vital, both to allow the patient to participate in the selection
of music and to discuss the emotions and thoughts the music
elicits (Bailey, 1986).
In Bailey’s review of music therapy in 1986, she said that a music therapist can
usually categorize a client’s experience with music into one of three genres: performer,
listener, or “event-er” (p. 26). A performer is defined as a person who has practiced
creating their own music, either by singing, playing an instrument, or composing music.
Anyone who has spent time keenly listening to music is classified as a listener. Lastly,
an event-er is described as a person whose only interaction with music is when it is
incorporated into another event, such as a wedding. All three of these groups can
benefit from listening to music, although they can all be given different tasks –
performers are told to sing or play along, listeners are told to listen and critique, and
event-ers are told to visualize people, places, and events to go along with the music.
Furthermore, performers can create their own music to go along with what they are
hearing.
As a general rule, the music chosen for therapy should be harmonious, steady,
gentle, and relaxing. Instrumental music is the most widespread choice, although music
that incorporates singing is still substantially used (Bailey, 1986). The iso-principle is a
rather common method of music selection and is based on the idea of slowly converting
the patient’s mood from its present state to a more desirable one (Maslar, 1986). First

music is found that matches the patient’s emotional state (be it lonely, fearful, etc.), and
then it is gradually modified until the songs being played are cheerful and comforting
and the patient’s disposition is the same (Bailey, 1986). Other factors can also influence
what music is chosen, such as the patient’s coping abilities (because music can evoke
strong emotions and feelings) and musical preferences (Bailey, 1986; Maslar, 1986;
Michel & Chesky, 1995; http://www.musictherapy.org/).
Effectiveness
The vast majority of studies that regard music therapy for pain managements
focus on acute pain, such as dentistry, labor, and postoperative pains. These studies
conclusively find it to be effective for reducing a patient’s pain level (Bailey, 1986;
Locsin, 1981; Maslar, 1986; Melzack, Weisz, & Sprague, 1963; Michel & Chesky, 1995;
http://www.musictherapy.org/). In Melzack, Weisz, and Sprague’s study, where they
evaluated how music and suggestion contributed to pain, they discovered that music
therapy works best for slowly rising pain as opposed to sudden, sharp pain (1963).
Music therapy alleviates pain both psychologically and physiologically (Maslar, 1986;
Melzack, Weisz, & Sprague, 1963).
Melzack, Weisz, and Sprague evaluated forty-two Tufts
University students, each of whom was provided with
headphones and a listening device (1963). The experimental
group’s listening devices enabled them to adjust levels of music
and white noise, and the control group’s listening devices did
not produce any sound, but they were told it emitted an
ultrasonic sound. Some members of each group were told that the device would allow

them to endure more pain, but others were told nothing. Their fingers were then placed
into an ice water bucket and the amount of time that they could tolerate the freezing
water was measured. From this study, Melzack, Weisz, and Sprague were able to
conclude that although neither the music alone nor just the suggestion that the
“ultrasonic” apparatus would work significantly elongated the amount of time of the
individual’s tolerance (their p-values were 0.073 and 0.254, respectively), when those
two factors were combined, the results improved dramatically, with a p-value of 0.006.
In 1981, Locsin performed a post-operative study on twenty-four women who
underwent gynecologic or obstetric surgery, testing how music influenced their pain
over the first forty-eight hours after their surgery. The experimental group listened to
music for fifteen minutes every two hours, after which their pain levels were
documented; the control group simply had their degree of pain recorded every two
hours. Pain was measured in four different ways. The first method was to utilize the
“Overt Pain Reaction Rating Scale (OPRRS),” a scale devised by the experimenters
that ranked different observations of pain severity (p. 21). They also measured pulse,
blood pressure, and the use of pain medications. The results of their study were that
OPRRS, the blood pressure measurements, and the amount of pain medication used all
showed marked decreases in pain for the experimental groups for the full forty-eight
hours, but that the pulse data only showed differences in the last twenty-four hours.
After the experiment, they also questioned the women about their post-operative pain,
and those who had taken part in the music therapy recounted less pain.
Physiological Causes

Both Maslar and Melzack, Weisz, and Sprague attributed the decrease in pain to
the fact that it hinders signals in the brainstem that are triggered by pain (1986, 1963).
Maslar goes on to explain that this occurs because of Melzack’s Gate Control Theory,
which states that the spinal cord is able to control the flow of nerve impulses to the
brain, and that music affects the workings of these “gates”. She says:
This theory validates the fact that it is the sensory-discriminating capabilities of
an individual that will decide the amount, perception, and responses to the pain.
Melzack’s Gate Control Theory substantiates using music as a distraction away
from the pain stimulus, and gives a foundation on which future research can be
based. (p.216)
When multiple separate stimuli simultaneously occur, only the
strongest enters consciousness (Maslar, 1986).
Psychological Causes
The most documented psychological reason that music therapy reduces pain is
that it simply distracts the patient and directs focus away from him- or herself (Bailey,
1986; Locsin, 1981; Maslar, 1986; Melzack, Weisz, & Sprague, 1963; Michel & Chesky,
1995). Furthermore, musical therapy improves mood and reduces stress, tension, and
anxiety, all of which contribute to pain (Maslar, 1986). Melzack, Weisz, and Sprague
also found that music therapy produces the best results when it is combined with the
assurance that it will help relieve the patient’s pain (1963).
Observable Effects

Although pain is primarily a subjective experience,
and thus the measurement of it is also fairly subjective,
there are some concrete indicators of pain that can be
used to assess its intensity. To begin with, pain elevates
pulse and blood pressure, but music therapy can regulate both symptoms (Locsin,
1981). Music therapy also reduces the amount of pain medications that a patient
intakes, an obvious sign of pain reduction (Locsin, 1981; Maslar, 1986). Lastly, those
patients who undergo music therapy have shortened recovery periods (Maslar, 1986).
Chronic Pain
All the research previously discussed has pertained to the treatment of acute
pain. Although the existing data leans toward music therapy being effectual for chronic
as well as acute pain, there are simply not enough studies to verify if it is in fact a
reliable method for treating chronic pain (McCraffrey & Freeman, 2003). In their 2003
inquiry, McCraffrey and Freeman analyzed how music therapy impacted chronic pain,
specifically osteoarthritis. Their study lasted for fourteen days and included sixty-six
senior citizens, all with osteoarthritis. The experimental group listened to music for
twenty minutes a day and the control group just sat quietly for twenty minutes a day.
Their results showed that in various ways of comparing the data, those who engaged in
music therapy always fared better. Firstly, on any given day, the pain levels of the
experimental group were lower after the music therapy than they had been before.
Secondly, for each individual day, the experimental group had less pain after listening to
the music than the control group did after sitting quietly. Lastly, over the course of the

fourteen days, the experimental group experienced an overall decrease of their chronic
pain, whereas the control group showed no substantial change.
Critique of Studies
Although all the aforementioned studies and articles are considered by the author
to be legitimate sources of scientific information, there are, as there is with any scientific
research, some weaknesses in them. Since pain is a subjective experience, it is hard to
measure, and the fact that people have different pain thresholds further complicates the
matter. Most of the studies lack concrete physical evidence; they rely solely or primarily
on the scientist’s observations and the patient’s reports of pain. In Maslar’s 1986 review
of music therapy for pain management, she perceived some additional shortcomings:
many experimenters used auditory stimulation instead of music, and those that did use
music failed to include in their publications what kind of music was used, preventing
replication. She states that using auditory stimulation as opposed to music in a scientific
study is understandable because of the need for objectivity (auditory stimulation is
easier to keep consistent) and because it prevents responses from being influence by
musical taste. Despite these advantages, auditory stimulation is still different from
music, and so one could argue that it produces different results and therefore studies
using just auditory stimulation are inapplicable to music therapy research.
Conclusion
Music therapy has been proved to be effective for lessening acute pain (Bailey,
1986; Locsin, 1981; Maslar, 1986; Melzack, Weisz, & Sprague, 1963; Michel & Chesky,
1995; http://www.musictherapy.org/). Melzack, Weisz, and Sprague found in their
experiments that when an individual listened to music and was told the music would

reduce their pain, the individual was able to tolerate the ice water surrounding their
fingers longer (1963). Locsin found when post-operative women listened to music, the
scientists observed less severe manifestations of pain and more regular blood
pressures and pulses (although the pulse only showed a significant difference in the
second day) and the women reported less pain when questioned directly (1981). In the
reviews by Bailey, Maslar, and Michel and Chesky, music therapy was further
documented to be effective.
Biologically, music therapy works by inhibiting the nerve impulses conveying pain
(Maslar, 1986; Melzack, Weisz, & Sprague, 1963). Psychologically, it succeeds in
lessening pain by distracting the patient from his or her pain and by positively affecting
other factors that contribute to pain, namely mood and stress (Bailey, 1986; Locsin,
1981; Maslar, 1986; Melzack, Weisz, & Sprague, 1963; Michel & Chesky, 1995). Music
therapy clearly demonstrates its functionality for alleviating acute pain in that it quickens
recovery, decreases pain medication consumption, and normalizes pulse and blood
pressure (Locsin, 1981; Maslar, 1986).
In conclusion, music therapy is highly recommended for acute pain management,
particularly when pain medication is not sufficient or when conditions prevent pain
medication from being utilized. Because it has next to no adverse side effects and the
few experiments performed have shown it to be helpful, music therapy is suggested for
chronic pain management as well. However, more research needs to be done on music
therapy and chronic pain before it becomes a commonplace practice, and it is strongly
advocated that more research on this topic be executed.
