Choreography is the act of creating a script or score for dancers. The result of this planning (i.e., the detailed description of the dance) is also called choreography.
The goals are:
By analogy, planning of any complex movements is also called choreography. For example, fight scenes such as in play are essentially complex pantomimes in which participants simulate hand-to-hand combat and need careful choreography to avoid injury.
In the SCA, a significant challenge is that very little choreography survives from period. So we often know that some dance was done by some name, but do not know its choreography. We are thus unable to reenact the dance and are left to recreate a dance with new choreography, but with the goal of it being a plausible relation of the dance in question.
