1. The first is singing. A musical is not an opera but it also has its own singing style. Although musicals are becoming more and more inclusive and popular, the most important singing method is still musical theater singing. The most important thing in musicals is not to sing well. But clear articulation and performance. The best way to learn is to seek guidance from professional teachers.
2. Performance. The foundation of musicals is drama and performance. A musical without acting has no soul. It’s important that songs serve story content and character development. Since the musical is a live performance, it requires a high level of presence from the actors. There is a difference between performing on stage and performing in front of the camera but both require genuine emotion. Anyone can perform in front of the camera, but not everyone can perform on stage.
3. Dance. There are roughly the following types of dances in musicals: ballet, tap, jazz and theater dance. Generally, the main characters in the play don't dance much, but the ensemble must be proficient in everything, or proficient in one or two items.
4. Combination. The most difficult part of a musical is to perfectly combine these three elements. Sing while you're acting, dance while you're singing, act while you're dancing, and do it naturally.
