In the first school year of children's music growth program "Music Master Class", children aged 6 to 13 are the main characters, Zhao Yiou is the head teacher, and Yang Yuying, Cao Ge, Han Lei and Terry Lin are the music teachers. Yan Su, a famous poet, is the headmaster.

"Music Master Class" makes the program return to pure music and singing. In ten months, the program group selected 16 pure "sounds of nature" from more than 6,000 children, and made completely contrarian regulations for them: no makeup on the program, no endorsement after becoming famous, etc. Everything is just to reduce the child's utilitarian heart to the lowest point.

In the second academic year of the Master of Music course, the plan was slightly revised. Kun Li was the head teacher, Ku Kuiqi, Tian Zhen, Han Lei and Sa Dingding were music teachers, President Yan Su died of illness, and the famous singer Li Guyi continued to be the principal.
