Detail from frontispiece to Thomas Wilson's Correct Method of German and French Waltzing (1816), showing nine positions of the Waltz, clockwise from the left (the musicians are at far left). At that time, the Waltz was a relatively new dance in England, and the fact that it was a couples dance (as opposed to the traditional group dances), and that the gentleman actually clasped his arm around the lady's waist, gave it a dubious moral status in the eyes of some.
