We will look at dance from the dimension Amusement and Engagement.
Often dance is a form of entertainment. You go to a performance to be amused. Or you dance yourself for your own pleasure. Sometimes choreographers want to raise an important social issue, which we call engagement.
Dance can be narrative, but can also be just about movements and shape, without the need to tell a story or share a message with the audience. Sometimes it is a combination of these.
Dance can also have a supporting function, for example in musical, opera or dance in a video clip for a song.
