Prior history During the lengthy time that has passed since the gods entered Valhalla at the end of Das Rheingold, Fafner has used the Tarnhelm to assume the form of a dragon, and guards the gold and the ring in the depths of the forest. Wotan has visited Erda seeking wisdom, and by her has fathered a daughter, Brünnhilde; he has fathered eight other daughters, possibly also by Erda. These, with Brünnhilde, form the Valkyries, whose task is to recover heroes fallen in battle and bring them to Valhalla, where they will protect the fortress from Alberich's assault should the dwarf recover the ring. Wotan has also wandered the earth, and with a woman of the Völsung race has fathered the twins Siegmund and Sieglinde, who have grown up separately and unaware of each other. From the Volsungs Wotan hopes for a hero who, unencumbered by the gods' treaties, will obtain the ring from Fafner. Act 1 As a storm rages, Siegmund finds shelter from his enemies in a large dwelling built around a massive ash-tree. Unarmed and wounded, he collapses with exhaustion. Sieglinde enters; she tells Siegmund that she is the wife of Hunding, and that he may rest here until Hunding's return. As they talk, they look at each other with growing interest and emotion. Siegmund gets ready to leave, telling Sieglinde that misfortune follows him and he does not want to bring it on her; she replies that misfortune dwells with her already. Hunding returns, and questions Siegmund's presence. Calling himself Wehwalt ("woeful"), Siegmund explains that he grew up in the forest with his parents and twin sister. One day he found their home burned down, his mother killed and his sister gone. Recently he fought with the relatives of a girl being forced into marriage. His weapons were destroyed, the bride was killed, and he was forced to flee. Hunding reveals that he is one of Siegmund's pursuers; Siegmund may stay, he says, but they must fight in the morning. Before leaving, Sieglinde gives a meaningful glance to a particular spot on the tree in which, the firelight reveals, a sword is buried to the hilt. Sieglinde returns, having drugged Hunding's drink. She reveals that she was forced into the marriage and that during their wedding feast, an old man appeared and plunged a sword into the trunk of the ash tree which neither Hunding nor any of his companions have been able to remove. She is longing for the hero who will draw the sword and save her. When Siegmund expresses his love for her, she reciprocates, and when he speaks the name of his father, Wälse, she recognises him as Siegmund, and realises that the sword was left for him. Siegmund then draws the sword from the tree. She reveals herself as Sieglinde, his twin sister. Siegmund names the sword "Nothung" and declares that it will be her protection. The two sing of their passionate love for each other, as the act ends. Act 2 On a high mountain ridge, Wotan instructs Brünnhilde, his Valkyrie daughter, to protect Siegmund in his forthcoming battle with Hunding. Fricka arrives, and in her role as goddess of family values demands that Siegmund and Sieglinde be punished for their adultery and incest. She scorns Wotan's argument that he requires Siegmund as a "free hero", who can further his plans to recover the ring from Fafner, uninhibited by Wotan's contracts. She retorts that Siegmund is not free but is Wotan's pawn, whose every move the god seeks to direct. Defeated by Fricka's logic, Wotan reluctantly agrees that he will not protect Siegmund. After Fricka leaves, the troubled Wotan gives Brünnhilde the full backstory, and with great sorrow rescinds his earlier instruction; he orders her to give the victory to Hunding, and then departs. Siegmund and Sieglinde now enter, and Sieglinde faints, consumed with guilt and exhaustion. Brünnhilde tells Siegmund of his impending death; he refuses to follow Brünnhilde to Valhalla when she tells him Sieglinde cannot accompany him. Siegmund still believes that his father's sword will assure him of victory over Hunding, but Brünnhilde tells him it has lost its power. Siegmund threatens to kill both Sieglinde and himself. Much moved, Brünnhilde decides to defy her father and grant victory to Siegmund. Hunding's call is heard; he arrives, and attacks Siegmund. Under Brünnhilde's power Siegmund begins to overpower Hunding, but Wotan appears and shatters Siegmund's sword with his spear. Hunding then stabs him to death. Brünnhilde gathers up the fragments of the sword and flees on horseback with Sieglinde. Contemptuously, Wotan strikes Hunding dead, and swearing that Brünnhilde will be punished for her defiance, sets out in pursuit of her. Act 3 The Valkyries congregate on the mountain-top, each carrying a dead hero and chattering excitedly. Brünnhilde arrives with Sieglinde, and begs her sisters for help, but they dare not defy Wotan. Sieglinde tells Brünnhilde that without Siegmund she no longer wishes to live. Brünnhilde informs her that she is pregnant by Siegmund, and urges her to remain alive for the child's sake, and to name the child Siegfried. Brünnhilde gives the fragments of the sword Nothung to Sieglinde, who thanks her for her loyalty and comfort, and resolves to save the child. As she departs, Wotan is heard approaching with great wrath. When Wotan arrives, the Valkyries vainly try to hide Brünnhilde. He faces her and declares her punishment: she is to be stripped of her Valkyrie status and become a mortal woman, to be held in defenceless sleep on the mountain, prey to any man who finds her. The other Valkyries protest, but when Wotan threatens them with the same, they flee. In a long discourse with Wotan Brünnhilde explains that she decided to protect Siegmund knowing that this was Wotan's true desire. Wotan consents to her request that he surround her resting place with a circle of fire that will protect her from all but the bravest of heroes. He bids her a loving farewell and lays her sleeping form down on a rock. He then summons Loge, the demigod of fire, who creates a circle of flames around her. Before slowly departing, Wotan pronounces that anyone with fear shall never pass through the fire.

The opera begins with the overture, which Mozart composed last. Act 1 Scene 1: A rough, rocky landscape Tamino, a handsome prince lost in a distant land, is pursued by a serpent and asks the gods to save him (aria: "Zu Hilfe! Zu Hilfe!" segued into trio: "Stirb, Ungeheuer, durch uns're Macht!"). He faints, and three ladies, attendants of the Queen of the Night, appear and kill the serpent. They find the unconscious prince extremely attractive, and each of them tries to convince the other two to leave. After arguing, they reluctantly decide to leave together. Tamino wakes up, and is surprised to find himself still alive. Papageno enters dressed as a bird. He describes his life as a bird-catcher, complaining he has no wife or girlfriend (aria: "Der Vogelfänger bin ich ja"). Tamino introduces himself to Papageno, thinking Papageno killed the serpent. Papageno happily takes the credit – claiming he strangled it with his bare hands. The three ladies suddenly reappear and instead of giving Papageno wine, cake and figs, they give him water, a stone and place a padlock over his mouth as a warning not to lie. They give Tamino a portrait of the Queen of the Night's daughter Pamina, with whom Tamino falls instantly in love (aria: "Dies Bildnis ist bezaubernd schön" / This image is enchantingly beautiful). The ladies return and tell Tamino that Pamina has been captured by Sarastro, whom they describe as a powerful, evil demon. Tamino vows to rescue Pamina. The Queen of the Night appears and promises Tamino that Pamina will be his if he rescues her from Sarastro (Recitative and aria: "O zittre nicht, mein lieber Sohn" / Oh, tremble not, my dear son!). The Queen leaves and the ladies remove the padlock from Papageno's mouth with a warning not to lie any more. They give Tamino a magic flute which has the power to change sorrow into joy. They tell Papageno to go with Tamino, and give him (Papageno) magic bells for protection. The ladies introduce three child-spirits, who will guide Tamino and Papageno to Sarastro's temple. Together Tamino and Papageno set forth (Quintet: "Hm! Hm! Hm! Hm!"). Scene 2: A room in Sarastro's palace Pamina is dragged in by Sarastro's slaves, apparently having tried to escape. Monostatos, a blackamoor and chief of the slaves, orders the slaves to chain her and leave him alone with her. Papageno, sent ahead by Tamino to help find Pamina, enters (Trio: "Du feines Täubchen, nur herein!"). Monostatos and Papageno are each terrified by the other's strange appearance and both flee. Papageno returns and announces to Pamina that her mother has sent Tamino to save her. Pamina rejoices to hear that Tamino is in love with her. She offers sympathy and hope to Papageno, who longs for a wife. Together they reflect on the joys and sacred duties of marital love (duet: "Bei Männern welche Liebe fühlen"). Finale. Scene 3: A grove in front of a temple The three child-spirits lead Tamino to Sarastro's temple, promising that if he remains patient, wise and steadfast, he will succeed in rescuing Pamina (Quartet: "Zum Ziele führt dich diese Bahn"). Tamino approaches the left-hand entrance and is denied access by voices from within. The same happens when he goes to the entrance on the right. But from the entrance in the middle, an old priest appears and lets Tamino in. (The old priest is referred to as "The Speaker" in the libretto, but his role is a singing role.) He tells Tamino that Sarastro is benevolent, not evil, and that he should not trust the Queen of the Night. He promises that Tamino's confusion will be lifted when Tamino approaches the temple in a spirit of friendship. Tamino plays his magic flute. Animals appear and dance, enraptured, to his music. Tamino hears Papageno's pipes sounding offstage, and hurries off to find him (aria: "Wie stark ist nicht dein Zauberton"). Papageno and Pamina enter, searching for Tamino (trio: "Schnelle Füße, rascher Mut"). They are recaptured by Monostatos and his slaves. Papageno plays his magic bells, and Monostatos and his slaves begin to dance, and exit the stage, still dancing, mesmerised by the beauty of the music (chorus: "Das klinget so herrlich"). Papageno and Pamina hear the sound of Sarastro's retinue approaching. Papageno is frightened and asks Pamina what they should say. She answers that they must tell the truth. Sarastro enters, with a crowd of followers. (chorus: "Es lebe Sarastro!") Pamina falls at Sarastro's feet and confesses that she tried to escape because Monostatos had forced his attentions on her. Sarastro receives her kindly and assures her that he wishes only for her happiness. But he refuses to return her to her mother, whom he describes as a proud, headstrong woman, and a bad influence on those around her. Pamina, he says, must be guided by a man. Monostatos brings in Tamino. The two lovers see one another for the first time and embrace, causing indignation among Sarastro's followers. Monostatos tells Sarastro that he caught Papageno and Pamina trying to escape, and demands a reward. Sarastro, however, punishes Monostatos for his lustful behaviour toward Pamina, and sends him away. He announces that Tamino must undergo trials of wisdom in order to become worthy as Pamina's husband. The priests declare that virtue and righteousness will sanctify life and make mortals like gods ("Wenn Tugend und Gerechtigkeit"). Act 2 Scene 1: A grove of palms The council of priests of Isis and Osiris, headed by Sarastro, enters to the sound of a solemn march. Sarastro tells the priests that Tamino is ready to undergo the ordeals that will lead to enlightenment. He invokes the gods Isis and Osiris, asking them to protect Tamino and Pamina (Aria and chorus: "O Isis und Osiris"). Scene 2: The courtyard of the Temple of Ordeal Tamino and Papageno are led in by two priests for the first trial. The two priests advise Tamino and Papageno of the dangers ahead of them, warn them of women's wiles and swear them to silence (Duet: "Bewahret euch von Weibertücken"). The three ladies appear and try to frighten Tamino and Papageno into speaking. (Quintet: "Wie, wie, wie") Papageno cannot resist answering the ladies, but Tamino remains aloof, angrily instructing Papageno not to listen to the ladies' threats and to keep quiet. Seeing that Tamino will not speak to them, the ladies withdraw in confusion. Scene 3: A garden Pamina is asleep. Monostatos approaches and gazes upon her with rapture. (Aria: "Alles fühlt der Liebe Freuden") He is about to kiss the sleeping Pamina, when the Queen of the Night appears. Monostatos hides. In response to the Queen's questioning, Pamina explains that Tamino is joining Sarastro's brotherhood and she is thinking of accompanying him too. The Queen is not pleased. She explains that her husband was the previous owner of the temple and on his deathbed, gave the ownership to Sarastro instead of her, rendering the Queen powerless (this is in the original libretto, but is usually omitted from modern productions, to shorten the scene with Pamina and her mother). She gives Pamina a dagger, ordering her to kill Sarastro with it and threatening to disown her if she does not. (Aria: "Der Hölle Rache kocht in meinem Herzen"). She leaves. Monostatos returns and tries to force Pamina's love by threatening to reveal the Queen's plot, but Sarastro enters and drives him off. Pamina begs Sarastro to forgive her mother and he reassures her that revenge and cruelty have no place in his domain (Aria: "In diesen heil'gen Hallen"). Scene 4: A hall in the Temple of Ordeal Tamino and Papageno are led in by priests, who remind them that they must remain silent. Papageno complains of thirst. An old woman enters and offers Papageno a cup of water. He drinks and teasingly asks whether she has a boyfriend. She replies that she does and that his name is Papageno. She disappears as Papageno asks for her name, and the three child-spirits bring in food, the magic flute, and the bells, sent from Sarastro (Trio: "Seid uns zum zweiten Mal willkommen"). Tamino begins to play the flute, which summons Pamina. She tries to speak with him, but Tamino, bound by his vow of silence, cannot answer her, and Pamina begins to believe that he no longer loves her. (Aria: "Ach, ich fühl's, es ist verschwunden") She leaves in despair. Scene 5: The pyramids The priests celebrate Tamino's successes so far, and pray that he will succeed and become worthy of their order (Chorus: "O Isis und Osiris"). Pamina is brought in and Sarastro instructs Pamina and Tamino to bid each other farewell before the greater trials ahead, alarming them by describing it as their "final farewell". (Trio: Sarastro, Pamina, Tamino – "Soll ich dich, Teurer, nicht mehr sehn?" Note: In order to preserve the continuity of Pamina's suicidal feelings, this trio is sometimes performed earlier in act 2, preceding or immediately following Sarastro's aria "O Isis und Osiris".[f][30]) They exit and Papageno enters. The priests grant his request for a glass of wine and he expresses his desire for a wife. (Aria: "Ein Mädchen oder Weibchen"). The elderly woman reappears and warns him that unless he immediately promises to marry her, he will be imprisoned forever. When Papageno promises to love her faithfully (muttering that he will only do this until something better comes along), she is transformed into the young and pretty Papagena. Papageno rushes to embrace her, but the priests drive him back, telling him that he is not yet worthy of her. Finale. Scene 6: A garden The three child-spirits hail the dawn. They observe Pamina, who is contemplating suicide because she believes Tamino has abandoned her. The child-spirits restrain her and reassure her of Tamino's love. (Quartet: "Bald prangt, den Morgen zu verkünden"). Scene change without interrupting the music, to Scene 7: Outside the Temple of Ordeal Two men in armor lead in Tamino. They recite one of the formal creeds of Isis and Osiris, promising enlightenment to those who successfully overcome the fear of death ("Der, welcher wandert diese Strasse voll Beschwerden"). This recitation takes the musical form of a Baroque chorale prelude, to a tune inspired by Martin Luther's hymn "Ach Gott, vom Himmel sieh darein" (Oh God, look down from heaven).[g][32] Tamino declares that he is ready to be tested. Pamina calls to him from offstage. The men in armour assure him that the trial by silence is over and he is free to speak with her. Pamina enters and declares her intention to undergo the remaining trials with him. She hands him the magic flute to help them through the trials ("Tamino mein, o welch ein Glück!"). Protected by the music of the magic flute, they pass unscathed through chambers of fire and water. Offstage, the priests hail their triumph and invite the couple to enter the temple. Scene change without interrupting the music, to Scene 8: A garden with a tree Papageno despairs at having lost Papagena and decides to hang himself (Aria/Quartet: "Papagena! Papagena! Papagena! Weibchen, Täubchen, meine Schöne") The three child-spirits appear and stop him. They advise him to play his magic bells to summon Papagena. She appears and, united, the happy couple stutter in astonishment and make bird-like courting sounds at each other. They plan their future and dream of the many children they will have together (Duet: "Pa... pa... pa..."). Scene change without interrupting the music, to Scene 9: A rocky landscape outside the temple; night The traitorous Monostatos appears with the Queen of the Night and her three ladies. They plot to destroy the temple ("Nur stille, stille") and the Queen confirms that she has promised her daughter Pamina to Monostatos. But before the conspirators can enter the temple, they are magically cast out into eternal night. Scene change without interrupting the music, to Scene 10: The Temple of the Sun Sarastro announces the sun's triumph over the night, and hails the dawn of a new era of wisdom and brotherhood. Animals appear again and dance in the sun.
