At this time, the ballet was accompanied by special music, and the composer used music to set off the atmosphere, explain the plot and portray the personality characteristics of the characters in the play, which became the soul of the dance. Dancers also make a series of movements and techniques with the music of ballet to create vivid artistic images. This kind of "special music" of romantic ballet has changed the previous practice of actors choosing their own music, making ballet and music perfectly integrated, thus creating a new artistic world of romantic ballet.
