Final answer:
Nora from A Doll's House dances the Tarantella, an Italian folk dance which she must perform at a fancy-dress ball, practicing ardently as she equates the performance with a significant personal crisis.
Step-by-step explanation:
The character Nora from Henrik Ibsen's play A Doll's House dances the Tarantella, which is a traditional Italian folk dance. She learns this dance while in Capri and her husband, Torvald, wants her to perform it at a fancy-dress ball. The passages from the play describe how Nora practices the Tarantella, insisting on the right music and tempo for her performance, and how the dance is critical for her as she feels that her life depends on it. The dance is characterized by a fast upbeat tempo, which reflects Nora's desperate energy and the intense situation she finds herself in within the narrative of the play.
