The research content of music psychology and music therapy is very wide, such as the reflection of the physical characteristics of sound on human hearing, musical memory, musical talent, musical imagination, as well as the training of musical skills and the psychological state of music performance. wait.

Because it adopts the method of experimental psychology, various theories attach great importance to the basis of scientific experiments, thus gradually revising the purely theoretical speculations and theories based on subjective impressions in music, and is connected with the theory of music aesthetics. rise and form a part of musicology.

Psychoanalysts linked emotions and memory understanding, and later developed "music therapy". The perspective of "self-control" regards people as a self-regulating physiological system, which balances the body through the feedback of perception and activity cycles.

Most of the experimental results in contemporary music psychology are in music perception. There is a tendency to try to connect the psychology of percussion with the psychological process of music learning to explore the development process from primitive to complex musical behavior; to study the development of musical behavior from young children and even infants to highly professional skills in order to be more comprehensive and in-depth To study various issues of people's musical psychological state.

The development of music psychology:

There is an obvious trend of extending to brain neuroscience, demonstrating the asymmetry of the brain structure of musicians. Enhancement of cortical representations by finger movements of the left hand of instrumental musicians, bihemispheric representation and brain activation of instrumental music stimulation, long-term enhancement of spatial to temporal reasoning in preschool children induced by musical skill training, effects of unilateral temporal lobe resection on song perception and representation .

Music stimulates people's emotions. Music is controlled by the right hemisphere of the human brain. The earlier the right hemisphere is developed, the more it can enhance people's ability to think in images. Therefore, as soon as the fetus can perceive sounds, we can stimulate it with music, so that the little life can receive prenatal education under carefree conditions. This will be of great benefit to improving the intelligence and quality of our offspring.

Research also shows that only sounds that conform to 1/f fluctuations can bring beneficial stimulation and act on the brain through the central auditory conduction system, causing the excitability of nerve cells and changing the release of transmitters in the hypothalamus. , thereby regulating the activities of the endocrine system and autonomic nervous system, prompting the human body to secrete some healthy hormones, enzymes, acetylcholine, etc., to keep the body in an extreme state.

In nature, such as the sea, waves, waterfalls, streams, the sound of gentle breeze, some drum music, classic music, etc., hearing such sounds can make people feel calm and give people an invisible abstraction. comfort. This is the "1/f wave theory".
