Kathak is derived from the Vedic Sanskrit word Katha which means "story", and Kathaka which means "he who tells a story", or "to do with stories". The Kathak dance form emphasizes rhythmic foot movements, adorned with small bells (Ghungroo), and the movement harmonized to the music. The legs and torso are generally straight, and the story is told through a developed vocabulary based on the gestures of arms and upper body movement, facial expressions, stage movements, bends and turns.
