Dancers typically do the following:
Dancers spend years learning dances and perfecting their skills. They usually perform as part of a group and know a variety of dance styles, including ballet, musical theater, and modern dance. In addition to traditional performances in front of a live audience, many perform on TV, in videos on the Internet, and in music videos, where they also may sing or act. Many dancers perform in shows at casinos, theme parks, and on cruise ships.
Choreographers typically do the following:
Choreographers create original dances and develop new interpretations of existing dances. They work in theaters, dance companies, and movie studios. During rehearsals, they typically demonstrate dance moves, to instruct dancers in the proper technique. Many choreographers also perform the dance routines they create. Some choreographers work with performers who are not trained dancers. For example, the complex martial arts scenes performed by actors in movies are arranged by choreographers who specialize in martial arts.
Some dancers and choreographers hold other jobs between roles to make a living. Some people with dance backgrounds become dance teachers.
