Music, as an element often used in drama, can play a comprehensive role of contrast, revelation and technology in drama works.

Music can sublimate the theme of drama, create a specific stage atmosphere, enhance the stage effect of a specific scene, shape the emotions and images of the characters in the work, reveal the psychological activities of the characters, enhance the drama and artistry of the work, and tap the national characteristics of the drama work. On the technical level, music is a smooth agent to facilitate the natural transformation between different scenes of drama. Therefore, the significance of music to drama and its multiple functions in drama are very worthy of discussion.

Throughout the works that have remained immortal in the history of drama, there is no exception that music plays a key role in them. Proper insertion of musical tunes or rhythms can highlight the overall layering of the drama, interpret the plot of this scene or prompt the next scene, create a special stage atmosphere, and enhance the artistic effect of the whole drama, which is very obvious.
