Re:Opera 與 musical 的分別?

1.Musicals tell a story with a performance combined with dialogue, music, and dance; whereas an opera is a performance where music is the main focus of the performance. It is sometimes accompanied by libretto and rarely by dance.
2.A musical performer needs to be an actor first and then a singer and dancer; whereas in opera the performer needs to be a trained, classical singer first and then anything else second.
3.Musicals are made in popular styles of music and dance and always in the language of the audience; whereas opera is traditional and is always in the language of the original story or text written.
