Definitions of Dramaturgy

1. Dramaturgy is the art of dramatic composition and the representation of the main elements of drama on the stage. Some dramatists combine writing and dramaturgy when creating a drama. Others work with a specialist, called a dramaturg, to adapt a work for the stage.
Dramaturgy may also be defined, more broadly, as shaping a story into a form that may be acted. Dramaturgy gives the work or the performance a structure.
