A professional dancer is a paid performing artist who uses movement to convey stories and ideas. Professional dancers perform dance numbers on stage, in movies, on television, in music videos, at theme parks, on cruise ships, and more. They usually have expertise in a particular type of dance, such as jazz, ballet, modern, ballroom, or tap, but some excel in more than one of these areas. Being a professional dancer is a physically demanding job that often takes a lot of hard work. Dancers must practice regularly and prepare for auditions and rehearsals. They also spend a great deal of time learning complicated routines and must be able to remember choreography. In some cases, working dancers must be able to perform multiple high-energy shows each day. Dancers can perform solo or in a group. They may dance on stage in front of a live audience in a theatrical production or they may be filmed for TV, commercials, music videos, movies, internet productions, and more.
