Labanotation
Laban is a way and language for interpreting, describing, visualizing and notating all ways of human movement. Created by Rudolf Laban, LMA draws on his theories of effort and shape to describe, interpret and document human movement. Used as a tool by dancers, actors, musicians, athletes, physical and occupational therapists, it is one of the most widely used systems of human movement analysis.
