Literally means to "whirl" is a controlled turn on one leg, starting with one or both legs in plié and rising onto demi-pointe (usually for men) or pointe (usually for women). The non-supporting leg can be held in retiré position, or in attitude, arabesque level or second position. The pirouette may return to the starting position or finish in arabesque or attitude positions, or proceed otherwise. A pirouette is most often en dehors turning outwards toward the back leg, but can also be en dedans turning inwards toward the front leg. Although ballet pirouettes are performed with the hips and legs rotated outward ("turned out"), it is common to see them performed with an inward rotation ("parallel") in other genres of dance, such as jazz and modern.

Turning technique includes spotting, in which a dancer executes a periodic, rapid rotation of the head that serves to fix the dancer's gaze on a single spot. Spotting is particularly important in traveling turns such as tours chaînés or piqués because it helps the dancer control the direction of travel while keeping balanced.

Pirouettes can be executed with a single or multiple rotations.
