This document defines key elements of rhythm including beat, tempo, intensity, pitch, accent, meter, phrase, bar, count, note, measure, note pattern, and step pattern. Beat establishes the underlying pulse, tempo is the rate of speed, and intensity involves variation of stress. Meter divides music into measures through regular beat recurrence, while phrases group measures. A bar divides a staff into equal time measures and count marks the pulse beat or time limit. Notes represent musical tones that make up measures, and note and step patterns correspond to dance movements.
