The Dance Notation Bureau is a membership organization that seeks “to advance the art of dance through the use of a system of notation”. The Bureau uses Labanotation as the method that they employ to record dances. The notation process itself is interesting. A “notator” comes out to the rehursals for the dance and records the steps, but the documentation doesn’t stop there. Other things that are recorded include historical information, production information and marked musical scores. The cost for this service can vary widely, and it is based on things such as how many dancers are involved, how long the work is and the complexity of the movements.
