Drawing on the theory of brainstorming, this paper explores the application of brainstorming, a brain stimulation method, in visual teaching of music. The main results are as follows: visual music teaching mainly improves music skills, cultivates music aesthetics, and enhances communicative competence. Once introduced to music class, the creative thinking method of brainstorming enables the teacher to train the divergent and creative thinking of students. During music teaching, brainstorming stimulates the learning interest, boosts the learning confidence, and cultivates the independent thinking of students. The research findings lay a theoretical basis for music course reform.
