one method of choreography that merce cunningham is known for is
Merce Cunningham Cunningham used "non-representational" choreography which simply emphasizes movement, and does not necessarily represent any historical narrative, emotional situation, or idea. Such non-representational dance appears in many styles throughout history, but was not commonly used by ballet or Martha Graham, Cunningham's primary influences. In the use of chance procedures Cunningham abandoned the more traditional structured form of dance, he did not believe that a dance needs a beginning, middle or end.[16]
Irish stepdance Sometime in that decade or the one following, a dance teacher had his students compete with arms held firmly down to their sides, hands in fists, to call more attention to the intricacy of the steps. The adjudicator approved by placing the students well. Other teachers and dancers quickly followed the new trend. Movement of the arms is sometimes incorporated into modern Irish stepdance, although this is generally seen as a hybrid and non-traditional addition and is only done in shows and performances, not competitions.
