Scene 1 – The garden of the Commendatore
Leporello, Don Giovanni’s servant, complains of his lot (“Notte e giorno faticar” – “Night and day I slave away”). He’s keeping watch while Don Giovanni seduces the Commendatore’s daughter, Donna Anna. When the two appear: Giovanni is masked but Donna Anna is holding onto his arm. Something has transpired and she insists on knowing his true identity (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!”), before he can break free from her grasp she cries for help. The Commendatore appears and forces Giovanni to a duel. Donna Anna flees into the house. Giovanni slays the Commendatore with his sword and escapes with Leporello. Anna, returning with her fiancé, Don Ottavio, is horrified to see her father lying dead in a pool of his own blood. She makes him 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
Giovanni and Leporello arrive and hear a woman (Donna Elvira) singing of having been abandoned by her lover on whom she is seeking to wreak her revenge (“Ah, chi mi dice mai” – “Ah, who could ever tell me”). Giovanni starts to flirt with her, but he is the wretch she is seeking. He shoves Leporello forward, ordering him to tell Elvira the truth, and then hurries away.
Leporello tells Elvira Don Giovanni is not worth it. His conquests include 640 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”).
When she leaves, a marriage procession with Masetto and Zerlina enters. Don Giovanni and Leporello arrive soon after. 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 Giovanni means to remain behind with Zerlina, Masetto becomes angry (“Ho capito! Signor, sì” – “I understand! Yes, my lord!”). 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”).
Elvira arrives and thwarts the seduction (“Ah, fuggi il traditor” – “Flee from the traitor!”). She leaves with Zerlina. Ottavio and Anna enter, plotting vengeance on the still unknown murderer of Anna’s father. Anna, unaware that she is speaking to her attacker, pleads for Giovanni’s help. Giovanni, relieved that he is unrecognised, readily promises it, and asks who has disturbed her peace. Before she can answer, Elvira returns and tells Anna and Ottavio that Giovanni is a false-hearted seducer. Giovanni tries to convince Ottavio and Anna that Elvira is insane. (Quartet: “Non ti fidar, o misera” – “Don’t trust him, oh sad one”). As Giovanni leaves, Anna suddenly recognizes him as her father’s murderer. (Anna aria: “Or sai chi l’onore Rapire a me volse” – “Now you know who is the one having trying to rob me of my honour”). Ottavio, not convinced, resolves to keep an eye on his friend. (“Dalla sua pace la mia dipende” – “On her peace my peace depends”)
Leporello informs Giovanni that all the guests of the peasant wedding are in Giovanni’s house, that he distracted Masetto from his jealousy, but that Zerlina, returning with 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. (Giovanni’s “Champagne Aria”: “Fin ch’han dal vino calda la testa” – “Till they are tipsy”). They hasten to his 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 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, Giovanni reproaches Masetto for leaving Zerlina alone, and returns her temporarily to him. Giovanni then leads both to his ballroom, which has been lavishly decorated. Leporello invites three masked guests to the party: the disguised Ottavio, Anna and Elvira. Ottavio and Anna pray for protection, Elvira for vengeance (Trio: “Proteggra il giusto cielo” – “May the just heavens protect us”).
Scene 3 – Finale: 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. When Zerlina screams for help, Don Giovanni tries to fool the onlookers by dragging Leporello into the room and threatening to kill him for assaulting Zerlina. But Ottavio produces a pistol, the three guests unmask and declare that they know all. But despite being denounced on all sides, Don Giovanni escapes – for the moment.
Scene 1 – Outside Elvira’s house
Leporello threatens to leave Giovanni, but his master calms him with a peace offering of money. (Duet: “Eh via buffone” – “Come on, you hot-headed”). Wanting to seduce Elvira’s maid, Giovanni persuades Leporello to exchange cloak and hat with him. Elvira comes to her window. (Trio: “Ah taci, ingiusto core” – “Ah, be quiet unjust heart”). Seeing an opportunity for a game, Giovanni hides and sends Leporello out in the open dressed as Giovanni. From his hiding place Giovanni sings a promise of repentance, expressing a desire to return to her, while Leporello poses as Giovanni and tries to keep from laughing. Elvira is convinced and descends to the street. Leporello, continuing to pose as Giovanni, leads her away to keep her occupied while Giovanni serenades her maid with his mandolin. (“Deh vieni alla finestra” – “Ah, come to the window”).
Before Giovanni can complete his seduction of the maid, Masetto and his friends arrive, searching for Giovanni and intending to kill him. Giovanni (dressed as Leporello) convinces the posse that he also hates Giovanni, and joins the hunt. After cunningly dispersing Masetto’s friends (Giovanni aria: “Metà di voi qua vadano” – “Half of you go this way”), 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 Elvira. (Sextet: “Sola, sola in buio loco” – “All alone in this dark place”). As he tries to escape, Ottavio arrives with Anna, consoling her in her grief. Just as Leporello is about to slip through the door, which he has difficulty finding, Zerlina and Masetto open it and, seeing him dressed as Giovanni, catch him before he can escape. When Anna and Ottavio notice what is going on all move to surround Leporello, threatening him with death. Elvira tries to protect the man whom she thinks is Giovanni, claiming that he is her husband and begging for pity. The other four are resolved to punish the traitor, but Leporello removes his cloak to reveal his true identity. He begs everyone’s forgiveness and, seeing an opportunity, runs off (Leporello aria: “Ah pietà signori miei” – “Ah, have mercy, my lords”). Given the circumstances, Ottavio is convinced that Giovanni was the murderer of Donna Anna’s father (the deceased Commendatore) and swears vengeance (“Il mio tesoro” – “My treasure” – though in the Vienna version this was cut). Elvira is still furious at Giovanni for betraying her, but she also feels sorry for him. (“Mi tradì quell’alma ingrata” – “That ungrateful wretch betrayed me”).
Leporello tells Don Giovanni of his brush with danger, and Giovanni taunts him, saying that he took advantage of his disguise as Leporello, by trying to seduce one of Leporello’s girlfriends. But the servant is not amused, suggesting it could have been his wife, and Don Giovanni laughs aloud at his servant’s protests. The voice of the statue warns 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 sacrilegious one who gave me death” (Dell’empio che mi trasse al passo estremo qui attendo la vendetta). The servant trembles, but the unabashed Giovanni orders him to invite the statue to dinner, threatening to kill him if he does not. Leporello makes several attempts to invite the statue to dinner but for fear cannot complete the task (Duet: “O, statua gentilissima” – “Oh most kind statue”). It falls upon Don Giovanni himself to complete the invitation, thereby sealing his own doom. Much to his surprise, the statue nods its head and responds affirmatively.
Scene 4 – Donna Anna’s room.
Ottavio pressures Anna to marry him, but she thinks it 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”).
Giovanni revels in the luxury of a great meal, served by Leporello, and musical entertainment during which the orchestra plays then-contemporary late 18th century opera music: “O quanto in 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). (Finale “Già la mensa preparata” – “Already the table is prepared”). Elvira appears, saying that she no longer feels resentment for Giovanni, only pity. (“L’ultima prova dell’amor mio” – “The final proof of my love”). Surprised by her lack of hatred, Giovanni asks what it is that she wants, and she begs him to change his life. 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 angered, Elvira gives up and leaves. A moment later, her scream is heard from outside the walls of the palace, and she returns only to flee through another door. Giovanni orders Leporello to see what has upset her; upon peering outside, the servant 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 Giovanni opens it himself, revealing the statue of the Commendatore. With the D minor music from the overture now accompanying the bass voice (“Don Giovanni! A cenar teco m’invitasti” – “Don Giovanni! You invited me to dine with you”), the Commendatore offers a last chance to repent, but Giovanni adamantly refuses. The statue sinks into the earth and drags Giovanni down with him. Hellfire, and a chorus of demons, surround Don Giovanni as he is carried below.
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. Giovanni is dead. Anna and Ottavio will marry when Anna’s year of mourning is over; Elvira will spend the rest of her life in a convent; 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”). In the past, the final ensemble was sometimes omitted by conductors who claimed that the opera should end when the title character dies. However, this approach has not survived, and today’s conductors almost always include the finale in its entirety. The return to D major and the innocent simplicity of the last few bars conclude the opera.
