They also may perform modern dance, which allows more free movement and self-expression. Others perform in dance adaptations for musical shows, in folk, ethnic, tap, and jazz dances, and in other popular kinds of dancing. In addition to being an art form for its own sake, dance also complements opera, musical comedy, television, movies, music videos, and commercials. Therefore, many dancers sing and act, as well as dance. Dancers most often perform as a group, although a few top artists dance solo.
Many dancers combine stage work with teaching or choreographing.
Choreographers create original dances. They may also create new interpretations to traditional dances like the Nutcracker since few dances are written down. Choreographers instruct performers at rehearsals to achieve the desired effect. They also audition performers. Dancing is physically demanding and strenuous.
