What is a dance duet in ballet called?

In ballet, a pas de deux (French, literally "step of two") is a dance duet in which two dancers, typically a male and a female, perform ballet steps together. The pas de deux is characteristic of classical ballet and can be found in many well-known ballets, including "leeping Beauty", "Swan Lake", and "Giselle". It is most often performed by a male and a female (a 'danseur' and a 'ballerina') though there are exceptions, such as in the film "White Nights", in which a pas de deux is performed by Mikhail Baryshnikov and Gregory Hines.

The 'adagio' or 'adage' (meaning "slowly") part of a grand pas de deux features graceful and elaborate partnering by the dancing pair. In the adagio, the ballerina performs elegant, often slow and sustained movements while the danseur supports her. The danseur, in turn, strives to maintain a display of poise and seemingly effortless strength while providing support for the ballerina.

Emboîté is a small traveling step where each leg is alternately brought to cou-de-pied, passing the previous standing leg in doing so. Both legs shoot straight downward in the air, and land on one foot in cou-de-pied. This step is often done turning ("en tournant"), where each jump rotates 1/2 turn.

Entrée is the initial appearance of a lead character or characters of a ballet on stage.
