I have read books/websites on screenplay writing and drama, but so far I have been unable to find out if there are formatting conventions for dance performances. I'm not talking about ballet per se (I know there is a very complicated notation for the movements of the dancers), but about about writing what you might call a libretto for a musical pantomime/dance show. Think Lord of the Dance (on a much smaller scale). I am writing the "play", which functions mostly without words, and I describe where the dance numbers are placed and what they are supposed to express, I describe the sets, and I even have to give instructions to the composer. So far, I'm using the format for screenplays, but I don't know how to describe the music. In plain text? I feel like my normal prose inventory isn't enough to describe the many levels of such a production in a tidy and easy to read fashion. Help? Please?
