:Place: the country house of the Pasha (German "Bassa"), in Turkey :Time: 16th century
Act 1 After a lively overture Belmonte enters, looking for his betrothed, Konstanze, who, with her English servant, Blonde, has fallen into the hands of pirates and been sold to
Pasha Selim (Aria: "" – "Here surely I must find her"). Osmin, the Pasha's bad-tempered servant, comes to pluck
figs in the garden and contemptuously ignores Belmonte's questions (Aria: "" – "You may think, you've found a maiden"). Belmonte tries to obtain news of his servant, Pedrillo, who has been captured with the women and is serving as a servant in the Pasha's palace. Osmin replies with insults and abuse (Duet: "" – "The devil take you and your song, sir"). Belmonte leaves in disgust. Pedrillo enters and Osmin rages at him, vowing to get him tortured and killed in many different ways (Aria: "" – "These young men who go a-spying"). Osmin leaves and Belmonte enters and happily reunites with Pedrillo. Together, they resolve to rescue Konstanze and Blonde, who is Pedrillo's fiancée (Aria: "" – "Konstanze, Konstanze, to see thee again ... Oh what trembling"). Accompanied by a chorus of
Janissaries ("" – "Sing to the mighty Pasha Selim"), Pasha Selim appears with Konstanze, for whose love he strives in vain (Aria of Konstanze: "" – "How I loved him"). Pedrillo tricks the Pasha into hiring Belmonte as an architect. When Belmonte and Pedrillo try to enter the palace, Osmin bars their way, but they hurry past him anyway (Terzett: "" – "March! March! March! Clear off!").
Act 2 The Pasha has given Blonde to Osmin, to be his slave; however, she defiantly rebuffs her new master's rough lovemaking attempts (Aria: "" – "With smiles and kind caresses"), threatens to scratch out his eyes, and chases him out of the room (Duet: "" – "I'm going, but mark what I say"). Konstanze enters in distress (Aria: "" – "Oh what sorrow overwhelms my spirit ... Endless grief tortures my spirit"). The Pasha enters, demands Konstanze's love, and threatens to use force, but she resolutely rejects him (Aria: "" – "Tortures unrelenting"). Left alone, he muses on her determination to remain chaste, which increases his desire for her. Pedrillo informs Blonde that Belmonte has come and is planning to rescue them, filling Blonde with joy (Aria: "" – "Oh, the happy, happy day"). After singing a short ditty to boost his courage (Aria: "" – "Now Pedrillo, now for battle!"), Pedrillo invites Osmin to drink (Duet: "" – "Here's to Bacchus, long live Bacchus"). Despite his
religious prohibition against alcoholic beverages, Osmin drinks heavily and falls asleep. Konstanze joins Belmonte who declares his love (Aria: "" – "When tears of joy flow"). The two couples reunite (Quartet, Belmonte, Konstanze, Pedrillo, Blonde: "" – "Ah, Belmonte, ah my dear one!"). After their initial expressions of love and joy, Belmonte and Pedrillo both question anxiously whether their respective fiancees have remained faithful during their forced separation; to their delight, the women respond with indignation and dismay, and Blonde slaps Pedrillo's face. The two men apologize for their lack of confidence; the women forgive them for their offensive questions.
Act 3 Klaas and Pedrillo come to the garden with ladders (Aria, Belmonte: "" – "Love, only love, can now direct me"). Pedrillo attracts the attention of the women by singing a ballad about a rescue similar to the one he is planning (Romanze, Pedrillo: "" – "In Moorish lands a maiden fair"). However, Osmin enters, sees the ladders, and rouses the castle. Osmin exults in the prospect of seeing them all hanged (Aria: "" – "My triumphant hour's approaching"). Belmonte pleads for their lives and tells Pasha Selim that his father is a Spanish
Grandee and Governor of
Oran, named Lostados, and will pay a generous ransom. Unfortunately, Pasha Selim and Lostados are long-standing enemies. The Pasha rejoices in the opportunity to subject his enemy's son to a horrible death. He leaves Belmonte and Konstanze to bid each other a last farewell; they lovingly assure each other that being tortured to death will be a pleasure, so long as they get tortured to death together (Duet: "" – "What dreadful fate conspires against us.... Woe, you will die because of me"). However, the Pasha then decides that he can make a better point against Lostados by showing mercy and releasing Belmonte and his friends. All are set at liberty – much to the dismay of Osmin (Finale: "" – "Your noble mercy passes measure"). ==Recordings==
