Musicals attract a lot of crowd and are favorite among the general public who love to see the beautiful spectacle and sensational choreography. Music in other productions is used to either highlight an effect, express the emotion of a character. Sometimes it is also used depict the state of mind of a character, communicate a particular feeling to the audience.
