Nritya, also referred to as Nrit, Nritta, Natana or Natya, refers to "dance, act on the stage, act, gesticulate, play" in the Indian traditions. It is sometimes sub-divided into two forms: nritta or pure dance, wherein expression-less movements of a dancer play out the rhythms and phrases of the music; and nritya or expressive dance, wherein the dancer includes facial expression and body language to portray mood and ideas with the rhythmic movements to communicate with the audience.
