As long as human culture has been recorded, music has been the part and parcel of it as both a tool for entertainment as well as a prolific source of emotional expression and attachment—however, hundreds of years down the line, music is recognised as a therapeutic tool in the psychology field. Music therapy has emerged as one of the strong arms in psychotherapy emerging the media of music to promote psychological and emotional health. The use of music on the benefits, mechanism of action, and application of psychology therapy in treating mental health conditions is what will need to be known.

Can music heal?

Being a mode of communications, music has been one unique way to get deep-seated and strong emotional responses. It involves many parts of the brain, such as those related with emotion, memory, and movement, so it affords a very flexible way of affecting therapy. Using music, people can articulate feelings that they cannot otherwise speak about, and hence music offers a non-verbal channel for any emotion. This can be very helpful if someone is unable to tell another how they are feeling with words. The type of melodies, rhythms, and harmonies in music all mirror a man's emotional condition and provide a way of working out complicated feelings, like grief, anger, and joy.

Listening to relaxing music has been connected to lower levels of cortisol, a hormone associated with stress, and thus, promotes relaxation and reduces feelings of depression. The rhythmic elements of music help regulate the autonomic nervous system, thus slowing the heart rate and lowering blood pressure to alleviate the physical symptoms of stress. In addition, it also has a profound effect on mood and motivation.

It enhances mood and energy through the activation of pleasant or rewarding neurotransmitters, including dopamine, which helps individuals participate in therapeutic experiences or activities that might otherwise be challenging. Participating in music, either through listening or via singing or playing an instrument, has also been demonstrated to support memory, attention, executive functions, and other cognitive skills.

Mechanisms of music therapy

There are many levels on which the therapeutic mechanisms of music therapy lie. One of the most core, basic mechanisms include neuroplasticity, which can be said to be the nature of the brain to rearrange itself by forming new neural connections. Music has been found to boost neuroplasticity through the creation of new pathways in the brain capable of replacing or compensating for impaired ones. This is especially beneficial during rehabilitation, where music therapy helps in recovering from neurological disorders and traumatic brain injuries.

Another way it accomplishes this is by synchronising and regulating the functions of the brain and body with rhythm-based activities. It also assists with enhancing coordination and movement in the case of motor disabilities through the rhythmic playing of drums or clapping. Its rhythmic quality also paces respiration and heart rate, thereby allowing inflections that amplify relaxation and emotional self-regulation. Its capacity to activate memory suggests that music can be used therapeutically to emotions and experiences which may not at all be reached in more traditional talk therapy. Moreover, familiar songs can stimulate memories and be used for conversation as mediators for connections to their lives in people with dementia.

Other than this, music is an essentially social activity, entailing collective experiences, such as singing in a choir or playing in a band. These two exercises have a feeling of integration and oneness, which may help an individual overcome the feeling of depression and isolation. Group music therapy tends to be supportive, and one can express himself comfortably and relates well with others, hence leading to better living of an individual.

Music therapy has increasingly been used in a variety of clinical settings to treat a broad scope of psychological and emotional problems. Theoretically, it could be used as an adjunct treatment for depressive and anxiety disorders. Techniques, such as using music to imagine serene scenes, now commonly referred to as guided imagery with music, may facilitate the patient's relaxation and decrease the anxiety associated with the disorder. At this same time, making music, written or improvised, one gains a sense of accomplishment and increases self-worth, hence the cure for depression.

On someone who has been traumatised, music therapy offers a non-verbal approach to processing such memories. Music therapy gently takes such people to face and integrate such experiences while creating a safety place to express one's emptions, hence reducing PTSD. Music therapy has been surmised as a very effective modality in the context of autism spectrum disorder, with potential improvement areas being communication, social skills, and emotional stability. This wider path of using music through singing, instrumental play, or body movement gains greater versatility in expressions and relationships.

Music therapy is also a harbinger that gives a better and healthy lifestyle to patients of dementia and Alzheimer's. It enhances memory, decreases agitation, and can promote socialisation. Familiar songs and melodies may evoke a sense of identification and associated emotions and, therefore re-assurance. As one of the treatments available for individuals with substance use disorders, it also serves as a non-threatening release for emotional expression and helps such persons develop better coping skills. Thus, songwriting and lyric analysis could be used to encourage exercising the personal experience and the insight into issues that underlie substance abuse.

The future of music therapy

As music therapy grows, there is a greater trend for research into the understanding of the specific mechanisms involved in applying music to brain and behaviour. Just as exciting for the advances generated in neuroscience is the improved understanding of the way that different types of music and musical activities influence neural pathways, marking a revised impetus to explore hitherto untapped therapeutic potentials of music. Today, technology has an expanding role in music therapy, enabling the therapist to take advantage of virtual reality among other digital music interventions that provide newer and more effective ways for the bringing and personalisation of therapeutic intervention.
