Editing Rigoletto (section)

=== Act 1 ===
''Scene 1: Mantua. A magnificent hall in the ducal palace. Doors at the back open into other rooms, splendidly lit up. A crowd of lords and ladies in grand costumes are seen walking about in the rear rooms; page boys come and go. The festivities are at their height. Music is heard from offstage. The Duke and Borsa enter from a door in the back.''

At a ball in his palace, the Duke sings of a life of pleasure with as many women as possible, and mentions that he particularly enjoys cuckolding his courtiers: "''Questa o quella''" ("This woman or that"). He mentions to Borsa that he has seen an unknown beauty in church and desires to possess her, but he also wishes to seduce the Countess of Ceprano. Rigoletto, the Duke's hunchbacked court jester, mocks the husbands of the ladies to whom the Duke is paying attention, including the Count Ceprano. He humorously advises the Duke to get rid of Count Ceprano by prison, exile, or death. The Duke laughs indulgently, but Ceprano is not amused. Marullo, one of the guests at the ball, informs the courtiers that Rigoletto has a "lover", which astonishes them. (Marullo is not aware that the "lover" is actually Rigoletto's daughter.) The courtiers, at Ceprano's suggestion, resolve to take vengeance on Rigoletto for making fun of them. The festivities are interrupted by the arrival of the elderly Count Monterone, whose daughter the Duke had seduced. Rigoletto provokes him further by making fun of his helplessness to avenge his daughter's honor. Monterone confronts the Duke, and is immediately arrested by the Duke's guards. Before being led off to prison, Monterone curses both the Duke for the attack on his daughter and Rigoletto for having mocked his righteous anger. The curse terrifies Rigoletto, who believes the popular superstition that an old man's curse has real power.

''Scene 2: The end of a dead-end street. On the left, a house of discreet appearance with one small courtyard surrounded by walls. In the yard there is one tall tree and a marble seat; in the wall, a door that leads to the street; above the wall, a terrace supported by arches. The second floor door opens on to the said terrace, which can also be reached by a staircase in front. To the right of the street is the very high wall of the garden and a side of the Ceprano palace. It is night.''

Preoccupied with the old man's curse, Rigoletto approaches the house where he is concealing his daughter from the world and is accosted by the assassin Sparafucile, who walks up to him and offers his services. Rigoletto declines for the moment, but leaves open the possibility of hiring Sparafucile later, should the need arise. Sparafucile wanders off, after repeating his own name a few times. Rigoletto contemplates the similarities between the two of them: "Pari siamo!" ("We are alike!"); Sparafucile kills men with his sword, and Rigoletto uses "a tongue of malice" to stab his victims. Rigoletto opens a door in the wall and embraces his daughter Gilda. They greet each other warmly: "Figlia!" "Mio padre!" ("Daughter!" "My father!"). Rigoletto has been concealing his daughter from the Duke and the rest of the city, and she does not know her father's occupation. Since he has forbidden her to appear in public, she has been nowhere except to church and does not even know her own father's name.

When Rigoletto has gone, the Duke appears and overhears Gilda confess to her nurse Giovanna that she feels guilty for not having told her father about a young man she had met at the church. She says that she fell in love with him, but that she would love him even more if he were a student and poor. As she declares her love, the Duke enters, overjoyed. Gilda, alarmed, calls for Giovanna, unaware that the Duke had given her money to go away. Pretending to be a student, the Duke convinces Gilda of his love: "È il sol dell'anima" ("Love is the sunshine of the soul"). When she asks for his name, he hesitantly calls himself Gualtier Maldè. Hearing sounds and fearing that her father has returned, Gilda sends the Duke away after they quickly trade vows of love: "Addio, addio" ("Farewell, farewell"). Alone, Gilda meditates on her love for the Duke, whom she believes is a student: "Gualtier Maldè!... [[Caro nome che il mio cor]]" ("Dearest name").

Later, Rigoletto returns: "Riedo!... perché?" ("I've returned!... why?"), while the hostile courtiers outside the walled garden (believing Gilda to be the jester's mistress, unaware she is his daughter) get ready to abduct the helpless girl. They tell Rigoletto that they are actually abducting the Countess Ceprano. He sees that they are masked and asks for a mask for himself; while they are tying the mask onto his face, they also blindfold him. Blindfolded and deceived, he holds the ladder steady while they climb up to Gilda's room: Chorus: "Zitti, zitti" ("Softly, softly"). With her father's unknowing assistance Gilda is carried away by the courtiers. Left alone, Rigoletto removes his mask and blindfold, and realizes that it was in fact Gilda who was carried away. He collapses in despair, remembering the old man's curse.
