This document discusses the fundamental rhythmic elements that are important for dance proficiency. It defines the underlying beat or pulse that serves as the constant unit of measurement for rhythmic structures. Measure refers to the grouping of underlying beats divided by bar lines. Rhythmic patterns are groupings of sounds or beats that fit within a unit of underlying beats. Phrasing involves grouping measures that give a feeling of unity, like a musical sentence. Other elements that affect rhythm include accent, tempo, and intensity. Understanding these elements facilitates learning dances and interpreting creative works.
