Choreographers are usually experienced former dancers or directors who are highly skilled in producing original dance numbers or reinterpreting classic dance numbers that have been written down and published. Choreographers can tailor new dance numbers to the specific needs of your performance. For classic dances from older plays, ballets or modern dance performances, choreographers perform demonstrations of the published movements and steps and teach your dancers how to perform them. Choreographers also keep your dancers healthy and happy by keeping your cast well-conditioned and fit.
Even if you have a clear vision in your head for how a performance's dances should accompany the music, it may not be clear to the dancers or actors. Through choreography, your vision can be properly manifested onstage. The choreographer's job is to realize the director's vision of a performance, so a choreographer can prove to be a valuable intermediary between yourself and your cast.
When you see a professional dance or theater company perform, the dances you see are usually complex compositions. A vague outline of the moves or steps will not produce a show that is pleasing to you, your cast or the audience. Choreographing your show ensures that even the smallest details will be rehearsed in advance. Therefore, your dancers will not be confused about their routines, and your audience will be treated to a more aesthetically developed work.
While some advanced dancers may be able to improvise exciting routines, nearly all dance shows require rehearsed choreography to be successful. Additionally, musicals with little to no movement or action are boring. Adding choreography to your show ensures the emotional and intellectual content of your play's music and lyrics are reinforced through dance. Additionally, choreographers can work with your set, lighting, musical and costume designers to ensure each component of your performance is in harmony with the others.
