Although the research on the mechanism of music therapy is still weak, many research reports can still explain some problems. Based on the research at home and abroad and some physiological experimental reports, the mechanism of music therapy can be summarized as follows:

1. Music stimulation can affect the release of some transmitters in the brain, such as acetylcholine and norepinephrine, thus improving the function of the cerebral cortex.

2. Music can directly act on the emotional centers of the human brain, such as hypothalamus and limbic system, and can adjust people's emotions in both directions.

3. The central hypothalamus, limbic system and brain stem reticular structure of emotional activity are closely related to the autonomic nervous system, and they are also the controllers of the activities of human internal organs and endocrine glands, so the emotional tension can directly lead to the pathological changes of some internal organs and suffer from "psychosomatic diseases". Music can regulate people's mood, so it can also help treat some psychosomatic diseases.

4. auditory pathway and the pain center are both in the temporal lobe of the brain. Music stimulates auditory pathway to have an interactive inhibitory effect on pain, and music can also increase the concentration of pituitary enkephalin, which can inhibit pain, so music has an analgesic effect.

5. Music can improve the brain function, coordinate the left and right hemispheres of the brain, thus promoting people's intellectual development, so it is often used in children's early intellectual development; Music can improve the ability of children with mental retardation, so music is widely used in special education.

6. Psychological research shows that music can influence personality, emotional cultivation is very important for personality growth, and music contains all aspects of people's emotions, so it can effectively cast personality; Music can act directly on the subconscious beyond consciousness, so it has special effect in psychotherapy; Music activity is a relatively orderly behavior, which helps to coordinate body and mind and establish harmonious interpersonal relationships, so it is widely used in behavioral therapy.
