Opera, musical comedy, television, movies, music videos, and commercials often include dancing as well. Many dancers sing and act, as well as dance. Dancers often work as a group. A few stars dance solo. Many dancers also teach or choreograph dances.
Choreographers create new dances.
They may also add changes to older dances. Some teach dancers to get the results they want. Rehearsals often are long and usually take place daily. Many rehearsals take place on weekends and holidays. Weekend travel is common when a show is on the road.
