Is there any special significance in dancing in musicals and movies?

Compared with other types of films, dance is the uniqueness of musical films.

Musical film is a special kind of film. It is similar to opera-many musicals can be said to be movie operas-but it is different from opera because of the characteristics of its films-musicals can use various narrative techniques of movies, and opera has very limited expression in this respect.

Musical movies are similar to operas, which made them popular in the 1930s, because people usually liked operas at that time! Even the early films made in the studio are basically the reappearance of opera. Mei, who holds the view that "the screen is the stage", did just that.

Musicals, like operas, have very high demands on music and songs. Especially songs with lyrics-most other movies only need the opening song and the ending song, and some can even be omitted; Musicals need a lot of songs to fill the film before they can be called musicals.
