Don Giovanni, a young, arrogant, and sexually promiscuous nobleman, abuses and outrages everyone else in the cast until he encounters something he cannot kill, beat up, dodge, or outwit.
Act 1
The overture begins with a thundering D minor cadence, followed by a short misterioso sequence which leads into a light-hearted D major allegro.
Scene 1 – The garden of the Commendatore
Leporello, Don Giovanni's servant, grumbles about his demanding master and daydreams about being free of him ("Notte e giorno faticar" – "Night and day I slave away"). He is keeping watch while Don Giovanni is in the Commendatore's house attempting to seduce or rape the Commendatore's daughter, Donna Anna. Don Giovanni enters the garden from inside the house, pursued by Donna Anna. Don Giovanni is masked and Donna Anna tries to hold him and to unmask him, shouting for help. (Trio: "Non sperar, se non m'uccidi, Ch'io ti lasci fuggir mai!" – "Do not hope, unless you kill me, that I shall ever let you run away!"). He breaks free and she runs off as the Commendatore enters the garden. The Commendatore blocks Don Giovanni's path and forces him to fight a duel. Don Giovanni kills the Commendatore with his sword and escapes with Leporello. Donna Anna, returning with her fiancé, Don Ottavio, is horrified to see her father lying dead in a pool of his own blood. She makes Don Ottavio swear vengeance against the unknown murderer. (Duet: "Ah, vendicar, se il puoi, giura quel sangue ognor!" – "Ah, swear to avenge that blood if you can!")
Scene 2 – A public square outside Don Giovanni's palace
Leporello tells Don Giovanni that he (Giovanni) is leading a rotten life; Don Giovanni reacts angrily. They hear a woman (Donna Elvira) singing of having been abandoned by her lover, on whom she is seeking revenge ("Ah, chi mi dice mai" – "Ah, who could ever tell me"). Don Giovanni starts to flirt with her, but it turns out he is the former lover she is seeking. The two recognize each other and she reproaches him bitterly. He shoves Leporello forward, ordering him to tell Donna Elvira the truth about him, and then hurries away.
Leporello tells Donna Elvira that Don Giovanni is not worth her feelings for him. He is unfaithful to everyone; his conquests include 640 women and girls in Italy, 231 in Germany, 100 in France, 91 in Turkey, but in Spain, 1,003 ("Madamina, il catalogo è questo" – "My dear lady, this is the catalogue"). In a frequently cut recitative, Donna Elvira vows vengeance.
Scene 3 – The open country
A marriage procession with Masetto and Zerlina enters. Don Giovanni and Leporello arrive soon after. Don Giovanni is immediately attracted to Zerlina, and he attempts to remove the jealous Masetto by offering to host a wedding celebration at his castle. On realizing that Don Giovanni means to remain behind with Zerlina, Masetto becomes angry ("Ho capito! Signor, sì" – "I understand! Yes, my lord!") but is forced to leave. Don Giovanni and Zerlina are soon alone and he immediately begins his seductive arts (Duet: "Là ci darem la mano" – "There we will entwine our hands").
Donna Elvira arrives and thwarts the seduction ("Ah, fuggi il traditor" – "Flee from the traitor!"). She leaves with Zerlina. Don Ottavio and Donna Anna enter, plotting vengeance on the still unknown murderer of Donna Anna's father. Donna Anna, unaware that she is speaking to her attacker, pleads for Don Giovanni's help. Don Giovanni, relieved that he is unrecognised, readily promises it, and asks who has disturbed her peace. Before she can answer, Donna Elvira returns and tells Donna Anna and Don Ottavio that Don Giovanni is a false-hearted seducer. Don Giovanni tries to convince Don Ottavio and Donna Anna that Donna Elvira is insane (Quartet: "Non ti fidar, o misera" – "Don't trust him, oh sad one"). As Don Giovanni leaves, Donna Anna suddenly recognizes him as her father's murderer and tells Don Ottavio the story of his intrusion, claiming that she was deceived at first because she was expecting a night visit from Don Ottavio himself, but managed to fight Don Giovanni off after discovering the imposture (long recitative exchange between Donna Anna and Don Ottavio). She repeats her demand that he avenge her and points out that he will be avenging himself as well (aria: "Or sai chi l'onore Rapire a me volse" – "Now you know who wanted to rob me of my honour"). In the Vienna version, Don Ottavio, not yet convinced (Donna Anna having only recognised Don Giovanni's voice, not seen his face), resolves to keep an eye on his friend ("Dalla sua pace la mia dipende" – "On her peace my peace depends").
Leporello informs Don Giovanni that all the guests of the peasant wedding are in Don Giovanni's house and that he distracted Masetto from his jealousy, but that Zerlina, returning with Donna Elvira, made a scene and spoiled everything. However, Don Giovanni remains cheerful and tells Leporello to organize a party and invite every girl he can find. (Don Giovanni's "Champagne Aria": "Fin ch'han dal vino calda la testa" – "Till they are tipsy"). They hasten to his palace.
Scene 4 – A garden outside Don Giovanni's palace
Zerlina follows the jealous Masetto and tries to pacify him ("Batti, batti o bel Masetto" – "Beat, O beat me, handsome Masetto"), but just as she manages to persuade him of her innocence, Don Giovanni's voice from offstage startles and frightens her. Masetto hides, resolving to see for himself what Zerlina will do when Don Giovanni arrives. Zerlina tries to hide from Don Giovanni, but he finds her and attempts to continue the seduction, until he stumbles upon Masetto's hiding place. Confused but quickly recovering, Don Giovanni reproaches Masetto for leaving Zerlina alone, and returns her temporarily to him. Don Giovanni then leads both offstage to his ballroom. Three masked guests – the disguised Don Ottavio, Donna Anna, and Donna Elvira – enter the garden. From a balcony, Leporello invites them to his master's party. They accept the invitation and Leporello leaves the balcony. Alone, Don Ottavio and Donna Anna pray for protection, Donna Elvira for vengeance (Trio: "Protegga il giusto cielo" – "May the just heavens protect us").
Scene 5 – Don Giovanni's ballroom
As the merriment, featuring three separate chamber orchestras on stage, proceeds, Leporello distracts Masetto by dancing with him, while Don Giovanni leads Zerlina offstage to a private room and tries to assault her. When Zerlina screams for help, Don Giovanni drags Leporello onstage from the room, accuses Leporello of assaulting Zerlina himself, and threatens to kill him. The others are not fooled. Don Ottavio produces a pistol and points it at Don Giovanni, and the three guests unmask and declare that they know all. But despite being denounced and menaced from all sides, Don Giovanni remains calm and escapes – for the moment.
Act 2
Scene 1 – Outside Donna Elvira's house
Leporello threatens to leave Don Giovanni, but his master calms him with a peace offering of money (Duet: "Eh via buffone" – "Go on, fool"). Wanting to seduce Donna Elvira's maid, and believing that she will trust him better if he appears in lower-class clothes, Don Giovanni orders Leporello to exchange cloak and hat with him. Donna Elvira comes to her window (Trio: "Ah taci, ingiusto core" – "Ah, be quiet unjust heart"). Seeing an opportunity for a game, Don Giovanni hides and sends Leporello out in the open wearing Don Giovanni's cloak and hat. From his hiding place Don Giovanni sings a promise of repentance, expressing a desire to return to her and threatening to kill himself if she does not take him back, while Leporello poses as Don Giovanni and tries to keep from laughing. Donna Elvira is convinced and descends to the street. Leporello, continuing to pose as Don Giovanni, leads her away to keep her occupied while Don Giovanni serenades her maid with his mandolin. ("Deh, vieni alla finestra" – "Ah, come to the window").
Before Don Giovanni can complete his seduction of the maid, Masetto and his friends arrive, looking for Don Giovanni in order to kill him. Don Giovanni poses as Leporello (whose clothes he is still wearing) and joins the posse, pretending that he also hates Don Giovanni. After cunningly dispersing Masetto's friends (Don Giovanni aria: "Metà di voi qua vadano" – "Half of you go this way. the others, go that way"), Don Giovanni takes Masetto's weapons away, beats him up, and runs off, laughing. Zerlina arrives and consoles the bruised and battered Masetto ("Vedrai carino" – "You'll see, dear one").
Scene 2 – A dark courtyard
Leporello abandons Donna Elvira. (Sextet: "Sola, sola in buio loco" – "All alone in this dark place"). As he tries to escape, he bumps into Don Ottavio and Donna Anna. Zerlina and Masetto also enter the scene. Everyone mistakes Leporello for Don Giovanni, whose clothes he is still wearing. They surround Leporello and threaten to kill him. Donna Elvira tries to protect the man who she thinks is Don Giovanni, claiming that he is her husband and begging the others to spare him. Leporello takes off Don Giovanni's cloak and reveals his true identity. He begs for mercy and, seeing an opportunity, runs off (Leporello aria: "Ah pietà signori miei" – "Ah, have mercy, my lords"). Don Ottavio is now convinced that Don Giovanni is the one who murdered Donna Anna's father (the deceased Commendatore). He swears vengeance ("Il mio tesoro" – "My treasure" – though in the Vienna version this was cut).
In the Vienna production of the opera, Zerlina follows Leporello and recaptures him. Threatening him with a razor, she ties him to a stool. He attempts to sweet-talk her out of hurting him. (Duet: "Per queste tue manine" – "For these hands of yours"). Zerlina goes to find Masetto and the others; Leporello escapes again before she returns. This scene, marked by low comedy, is rarely performed today. Also in the Vienna production, Donna Elvira is still furious at Don Giovanni for betraying her, but she also feels sorry for him. ("Mi tradì quell'alma ingrata" – "That ungrateful wretch betrayed me").
Scene 3 – A graveyard with the statue of the Commendatore.
Don Giovanni wanders into a graveyard. Leporello happens along and the two are reunited. Leporello tells Don Giovanni of his brush with danger, and Don Giovanni laughingly taunts him, saying that he took advantage of his disguise as Leporello by trying to seduce one of Leporello's girlfriends. The voice of the statue interrupts and warns Don Giovanni that his laughter will not last beyond sunrise. At the command of his master, Leporello reads the inscription upon the statue's base: "Here am I waiting for revenge against the scoundrel who killed me" (Dell'empio che mi trasse al passo estremo qui attendo la vendetta). The servant trembles, but Don Giovanni scornfully orders him to invite the statue to dinner, and threatens to kill him if he does not. Leporello makes several attempts to invite the statue to dinner but is too frightened to complete the invitation (Duet: "O, statua gentilissima" – "Oh most noble statue"). Don Giovanni invites the statue to dinner himself. Much to his surprise, the statue nods its head and responds affirmatively.
Scene 4 – Donna Anna's room
Don Ottavio pressures Donna Anna to marry him, but she thinks it is inappropriate so soon after her father's death. He accuses her of being cruel, and she assures him that she loves him, and is faithful ("Non mi dir" – "Tell me not").
Scene 5 – Don Giovanni's chambers
Don Giovanni revels in the luxury of a great meal, served by Leporello, and musical entertainment during which the orchestra plays music from popular (at the time) late-18th-century operas: "O quanto un sì bel giubilo" from Vicente Martín y Soler's Una cosa rara (1786), "Come un agnello" from Giuseppe Sarti's Fra i due litiganti il terzo gode (1782) and finally, "Non più andrai" from Mozart's own The Marriage of Figaro (1786). Leporello complains that he is sick and tired of hearing Mozart's aria everywhere all the time. (Finale "Già la mensa preparata" – "Already the table is prepared"). Donna Elvira enters, saying that she no longer feels resentment against Don Giovanni, only pity for him. ("L'ultima prova dell'amor mio" – "The final proof of my love"). Don Giovanni, surprised, asks what she wants, and she begs him to change his life. Don Giovanni taunts her and then turns away, praising wine and women as the "support and glory of humankind" (sostegno e gloria d'umanità). Hurt and angry, Donna Elvira gives up and leaves. Offstage, she screams in sudden terror. Don Giovanni orders Leporello to see what has upset her; when he does, he also cries out, and runs back into the room, stammering that the statue has appeared as promised. An ominous knocking sounds at the door. Leporello, paralyzed by fear, cannot answer it, so Don Giovanni opens it himself, revealing the statue of the Commendatore. With the rhythmic chords of the overture, now reharmonized with diabolic diminished sevenths accompanying the Commendatore ("Don Giovanni! A cenar teco m'invitasti" – "Don Giovanni! You invited me to dine with you"), the statue offers a last chance to repent, but Don Giovanni adamantly refuses. The statue disappears and Don Giovanni cries out in pain and terror as he is surrounded by a chorus of demons, who carry him down to Hell. Leporello, watching from under the table, also cries out in fear.
Donna Anna, Don Ottavio, Donna Elvira, Zerlina, and Masetto arrive, searching for the villain. They find instead Leporello hiding under the table, shaken by the supernatural horror he has witnessed. He assures them that no one will ever see Don Giovanni again. The remaining characters announce their plans for the future: Donna Anna and Don Ottavio will marry when Donna Anna's year of mourning is over; Donna Elvira will withdraw from society for the rest of her life; Zerlina and Masetto will finally go home for dinner; and Leporello will go to the tavern to find a better master.
The concluding ensemble delivers the moral of the opera – "Such is the end of the evildoer: the death of a sinner always reflects his life" ("Questo è il fin di chi fa mal, e de' perfidi la morte alla vita è sempre ugual"). As mentioned above, the final ensemble was customarily omitted from productions for over a century beginning with the original run in Prague, but it started to be performed again frequently in the 20th century and is now is usually included in productions of the opera. The return to D major and the innocent simplicity of the last few bars conclude the opera.

Place: Mantua
Time: the sixteenth century
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, and advises the Duke to get rid of him by prison 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 hit-man 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 sent her 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.
Act 2
A room in the ducal palace. There are doors on both sides as well as a larger one at the far end by the sides of which hang full length portraits of the Duke and his wife. There is one high-backed chair at a table covered with velvet and other furnishings.
The Duke is concerned that Gilda has disappeared: "Ella mi fu rapita!" ("She was stolen from me!") and "Parmi veder le lagrime" ("I seem to see tears"). The courtiers then enter and inform him that they have captured Rigoletto's mistress: Chorus: "Scorrendo uniti" ("We went together at nightfall"). By their description, he recognizes it to be Gilda and rushes off to the room where she is held: "Possente amor mi chiama" ("Mighty love beckons me"). Rigoletto enters singing and feigning nonchalance, but also looking anxiously for any trace of Gilda, whom he fears may have fallen into the hands of the Duke. The courtiers pretend not to notice his anxiety, but quietly laugh at him with each other. A page boy arrives with a message from the Duke's wife - the Duchess wishes to speak to her husband - but the courtiers reply suggestively that the Duke cannot be disturbed at the moment. Rigoletto realizes this must mean that Gilda is with the Duke. To the courtiers' surprise, he reveals that Gilda is his daughter. He first demands, then tearfully pleads with the courtiers to return her to him: "Cortigiani, vil razza dannata" ("Accursed race of courtiers"). Rigoletto attempts to run into the room in which Gilda is being held, but the courtiers block his way. After a time, Gilda enters, and Rigoletto orders the courtiers to leave him alone with her. The courtiers leave the room, believing Rigoletto has gone mad. Gilda describes to her father what has happened to her in the palace: "Tutte le feste al tempio" ("On all the holy days") and he attempts to console her. Monterone is led across the room on the way to prison and pauses in front of the portrait of the Duke to regret that his curse on the libertine has had no effect. As the guards lead Monterone away, Rigoletto mutters that the old man is mistaken; he, Rigoletto, the dishonored buffoon, shall make thunder and lightning rain from heaven onto the offender's head. He repeats this vow as Gilda pleads for mercy for her lover the Duke: Duet:"Sì! Vendetta, tremenda vendetta!" ("Yes! Revenge, terrible revenge!").
Act 3
The right bank of the river Mincio. On the left is a two-story house, half ruined. Through a large arch on the ground floor a rustic tavern can be seen as well as a rough stone staircase that leads to an attic room with a small bed which is in full view as there are no shutters. In the wall downstairs that faces the street is a door that opens to the inside. The wall is so full of holes and cracks that everything that happens inside is easily seen from the exterior. At the back of the stage are deserted areas by the river which flows behind a parapet that has half collapsed into ruins. Beyond the river is Mantua. It is night. Gilda and Rigoletto, both uneasy, are standing in the road; Sparafucile is seated at a table in the tavern.
A portion of Sparafucile's house is seen, with two rooms open to the view of the audience. Rigoletto and Gilda arrive outside. The Duke's voice can be heard from inside, singing "La donna è mobile" ("Woman is fickle"). Sparafucile's sister, Maddalena, has lured him to the house. Rigoletto and Gilda listen from outside as the Duke flirts with Maddalena. Gilda laments that the Duke is unfaithful; Rigoletto assures her that he is arranging revenge: "Bella figlia dell’amore" ("Beautiful daughter of love").
Rigoletto orders Gilda to put on a man's clothes to prepare to leave for Verona and tells her that he plans to follow later. After she leaves, he completes his bargain with the assassin, who is ready to murder his guest for 20 scudi. Rigoletto then withdraws.
With falling darkness, a thunderstorm approaches and the Duke decides to spend the rest of the night in the house. Sparafucile directs him to the upstairs sleeping quarters, resolving to kill him in his sleep.
Gilda, who still loves the Duke despite knowing him to be unfaithful, returns dressed as a man and stands outside the house. Maddalena, who is smitten with the Duke, begs Sparafucile to spare his life: "È amabile invero cotal giovinotto/ Ah, più non ragiono!...". Sparafucile reluctantly promises her that if by midnight another victim can be found, he will kill the other instead of the Duke. Gilda, overhearing this exchange, resolves to sacrifice herself for the Duke, and enters the house: "Trio: Se pria ch’abbia il mezzo la notte toccato". Sparafucile stabs her and she collapses, mortally wounded.
At midnight, when Rigoletto arrives with money, he receives a corpse wrapped in a sack, and rejoices in his triumph. Weighting it with stones, he is about to cast the sack into the river when he hears the voice of the Duke, sleepily singing a reprise of his "La donna è mobile" aria. Bewildered, Rigoletto opens the sack and, to his despair, discovers his dying daughter. For a moment, she revives and declares she is glad to die for her beloved: "V'ho ingannato" ("Father, I deceived you"). She dies in his arms. Rigoletto cries out in horror: "La maledizione!" ("The curse!")
