The charm of music lies in the sense of hearing, which sets off the mood of the story. On the one hand, it deepens the audience's understanding of the story, on the other hand, it renders a good viewing atmosphere. The purpose of this paper is to discuss the various manifestations of music in movies and explore the unique charm of music in movies.

Music is an expression that can reflect human emotions. It is just like words, and it has a unique expressive ability to strengthen the expression of emotions. In the narration of movie stories, the characters are dealt with. Since the birth of sound film, music has been developing with it, and the art of film is called sound painting art, which is conveyed through the combination of "seeing" and "listening". And this movie is not only beautiful, but also great, and it has the spirit and strength of God. In the French countryside in 1949, musician Clemente (Gerard Zuno) went to a boarding school for boys nicknamed "The Bottom of the Pond" as a supervisor. Most of the students in the school are difficult problem children, and corporal punishment is common here. The principal of the school (played by Francis Berland) only cares about his own future and is cruel and high-handed. Clement, who is quiet, tried to improve this situation in his own way. He re-created music works and organized a choir, and decided to use music to open students' closed hearts.

directing is like mixing music with the power of religion. If "the bottom of the pond" symbolizes our ugly, gloomy, morbid, sad and hopeless society, then these touching music are the source of beauty, the foundation of happiness and the seed of hope to save us.
