In drama, dance can be used to express emotions, tell a story, or create a mood. It can also be used to enhance the overall theatrical experience by adding movement and energy to the stage. For example, in the musical "Hamilton," dance is used to express the characters' emotions and tell the story of the American Revolution.
In musicals, dance is often used to tell the story, create an atmosphere, or provide a visual spectacle. It can also be used to enhance the musical numbers by adding movement and energy to the stage. For example, in the musical "The Lion King," dance is used to create the illusion of animals moving and interacting with each other.
So, while dance is often associated with musicals, it can also be used effectively in dramas and other forms of theater.
