In page Can-can:

"

Outside France, the can-can achieved popularity in music halls, where it was danced by groups of women in choreographed routines. This style was imported back into France in the 1920s for the benefit of tourists,[citation needed] and the "French Cancan" was born—a highly choreographed routine lasting ten minutes or more, with the opportunity for individuals to display their "specialities". The main moves are the high kick or battement, the rond de jambe (quick rotary movement of lower leg with knee raised and skirt held up), the port d'armes (turning on one leg, while grasping the other leg by the ankle and holding it almost vertically), the cartwheel and the grand écart (the flying or jump splits). It has become common practice for dancers to scream and yelp while performing the can-can.
