The Vien­nese Waltz is a rotary dance where the dancers are con­stantly turn­ing either in a clock­wise (nat­ural) or anti-clockwise (reverse) direc­tion inter­spersed with non-rotating change steps to switch between the direc­tion of rota­tion. A true Vien­nese waltz con­sists only of turns and change steps. Other moves such as the fleck­erls, American-style fig­ures and side sway or under­arm turns are mod­ern inven­tions and are not nor­mally danced at the annual balls in Vienna. Fur­ther­more, in a prop­erly danced Vien­nese Waltz, cou­ples do not pass, but turn con­tin­u­ously left and right while trav­el­ing coun­ter­clock­wise around the floor fol­low­ing each other.
