Why singing and playing musical instruments, in contrast to man-made noise, have a beneficial effect on the physiological and emotional state of a person?
The sound arising during singing only 15-20% goes into the outer space. The rest of the sound wave is absorbed by the internal organs, causing them to vibrate, which helps to stimulate and improve their functioning.
Playing musical instruments has a positive effect not only on the interhemispheric organization of auditory and motor functions, but also on the process of redistribution of mental functions between the left and right hemispheres of the brain (lateralization).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
