William C. Smith and Alexander B. F. Young, 1911 Encyclopædia Britannica, Volume 7… (1911)
“ The mind feels the beauty of emphasis and cadence in muscular motion, just as much as in musical notes. Then, the figure of the dance is frequently a circle or some more graceful curve or series of curves,—a fact which satisfies the dancer as well as the eye of the spectator. But all such effects are intensified by the use of music, which not only brings a perfectly distinct set of pleasurable sensations to dancer and spectator, but by the control of dancing produces an inexpressibly sweet harmony of sound and motion. ”
