"When quality education is implemented globally in the 21st century, preventing bullying on campus has become a topic of public concern, and the emotional problems of children and young people must not be ignored, so music education is one of the feasible preventive strategies. Since ancient times, the functions of music education in the East and the West have been moralized, with 'harmony', 'beauty' and 'goodness' as the core of music art. Until modern medical research has found that music not only has the functions of education, entertainment and aesthetics It can also adjust the function of the nervous system, eliminate depression, anxiety, tension and other bad emotions, promote the balance of body and mind, and help the health of the body and soul. Prevention of campus bullying can be prevented through music education, reducing social costs, recognizing subtle influences, cultivating morality, and optimizing emotions. In the 21st century, emphasis is placed on holistic education. Music education can be used as a core literacy course to cultivate the best recipe for lifelong learners."
