Claim: Moana contains songs.

The musical film is a film genre in which songs sung by the characters are interwoven into the narrative , sometimes accompanied by dancing .   The songs usually advance the plot or develop the film 's characters , though in some cases they serve merely as breaks in the storyline , often as elaborate `` production numbers '' .   The musical film was a natural development of the stage musical after the emergence of sound film technology . Typically , the biggest difference between film and stage musicals is the use of lavish background scenery and locations that would be impractical in a theater . Musical films characteristically contain elements reminiscent of theater ; performers often treat their song and dance numbers as if there is a live audience watching . In a sense , the viewer becomes the diegetic audience , as the performer looks directly into the camera and performs to it .
