Music can only be expressed by sound and felt by hearing, but this does not mean that when people are creating and enjoying music, only parts of the cerebral cortex corresponding to hearing are excited, and other parts are in a state of inhibition . In fact, musicians do not only use auditory channels, but use the whole body and mind to feel and experience, recognize and express life, which is no different from other types of artists. The difference is that in the process of artistic conception and artistic expression, musicians condense their various personal feelings into auditory images through visual thinking, and then express them in specific acoustic forms.
