The reason music has the effect of treating diseases is because music can play a special role in people's mental state and physical condition. This effect is achieved through psychological and physical effects.

In terms of psychological effects, music can directly affect people's emotions and behaviors. We know that music has various beats and rhythms, and the human body also has various physiological rhythms, such as pulse, breathing, etc. If they cooperate well, music can regulate the physiological rhythm. And because the human body has an obvious instinct to follow the rhythm of music, the speed of the music rhythm can also drive the rhythm of body movements. The "harp" in folk songs can reflect this effect. As a means of treatment, music can act on the psychology through artistic appeal and emotional guidance, which can not only enhance the body's disease resistance, but also eliminate mental blockages. Music with a distinct rhythm can uplift people's emotions, such as military music and marches, which generally have a distinct sense of rhythm and can make people excited, excited, and passionate; music with beautiful and melodious melody can make people feel calm, relaxed and happy. In addition, music can also affect people's emotions through tone. This phenomenon has been noticed as early as ancient Greece. They believe that the key of E is stable, the key of D is warm, the key of C is gentle, the key of B is sad, and the key of A is high.

We know that human emotional activities are closely related not only to the cerebral cortex, but also to the human endocrine system, autonomic nervous system, hypothalamus and limbic system. The limbic system of the brain is the highest center that regulates and controls the activities of human internal organs. In this way, music that makes people relaxed, happy, comfortable and cheerful can improve and strengthen the functions of the cerebral cortex, limbic system and autonomic nervous system, thereby better controlling and enhancing the normal activities of various internal organ systems of the human body. However, music therapy does not simply obtain therapeutic effects from appreciation; it is used as an activity to achieve therapeutic effects. Because the music itself is a structure, a practical and regular organization composed of various notes. To participate in music therapy activities, patients must learn and pay attention to the entirety of the music from beginning to end. In this way, the patient must concentrate and make a certain amount of effort, that is, through music activities, the patient can be trained to concentrate and have the ability to concentrate. However, many patients, especially those with mental illness and neurosis, lack this ability. At the same time, music activities can also train patients to master or recover some new skills, such as mastering the melody, tone, rhythm, harmony of various pieces of music through singing, and the ability to coordinate with others; mastering the skills of various musical instruments through musical instrument playing. Performance, playing method and ability to cooperate with each other; this can encourage patients to increase their enjoyment of life and understand the meaning of life, thus increasing their initiative and self-confidence in life, which is beneficial to physical and mental health.

In terms of physical effects, music can affect the physiological functions of the human body through sound. Sound is the vibration of sound waves, a kind of physical energy. Music is sound wave vibration of a certain frequency, which acts on various vibration systems in the human body to produce beneficial vibrations and coordinate the rhythm of various organs. This coordination is an important factor for physical and mental health. On the other hand, beautiful music sound waves act on the brain, increase nerve excitability, and promote the body to secrete some healthy hormones, enzymes, acetylcholine and other substances through the regulation of neurohumoral fluids, which regulate blood flow, promote blood circulation and It can stimulate gastrointestinal motility and saliva secretion, strengthen metabolism and other functions, thus making people energetic and full of youthful vitality. The use of music in foreign countries to replace anesthetic drugs for caesarean section and tooth extraction operations does not achieve results simply by diverting the patient's attention or suggesting effects. It, like acupuncture, has a physiological and biochemical basis. The mechanism of acupuncture analgesia is not fully understood, but it has been found to be related to the increase in endorphins in the human body. Therefore, differences in the rhythm, melody, speed, coordination, etc. of the music can show different effects such as sedative, exciting, analgesic, antihypertensive, and mood-regulating effects.

Because music can affect people’s physiological and psychological activities, especially emotional activities, people can use music to improve and regulate the physiological and psychological functions of the human body, thereby achieving disease treatment, health and fitness. , the purpose of improving health.
