The Marriage of Figaro continues the plot of The Barber of Seville several years later, and recounts a single "day of madness" (la folle journée) in the palace of Count Almaviva near Seville, Spain. Rosina is now the Countess; Dr. Bartolo is seeking revenge against Figaro for thwarting his plans to marry Rosina himself; and Count Almaviva has degenerated from the romantic youth of Barber into a scheming, bullying, skirt-chasing baritone. Having gratefully given Figaro a job as head of his servant-staff, he is now persistently trying to exercise his droit du seigneur – his right to bed a servant girl on her wedding night – with Figaro's bride-to-be, Susanna, who is the Countess's maid. He keeps finding excuses to delay the civil part of the wedding of his two servants, which is arranged for this very day. Figaro, Susanna, and the Countess conspire to embarrass the Count and expose his scheming. He retaliates by trying to compel Figaro legally to marry a woman old enough to be his mother, but it turns out at the last minute that she really is his mother. Through Figaro's and Susanna's clever manipulations, the Count's love for his Countess is finally restored.
Place: Count Almaviva's estate, Aguas-Frescas, three leagues outside Seville, Spain.
Overture
The overture is in the key of D major; the tempo marking is presto; i.e. very fast. The work is well known and often played independently as a concert piece.
Act 1
A partly furnished room, with a chair in the centre.
Figaro happily measures the space where the bridal bed will fit while Susanna tries on her wedding bonnet in front of a mirror (in the present day, a more traditional French floral wreath or a modern veil are often substituted, often in combination with a bonnet, so as to accommodate what Susanna happily describes as her wedding cappellino). (Duet: "Cinque, dieci, venti" – "Five, ten, twenty"). Figaro is quite pleased with their new room; Susanna far less so (Duettino: "Se a caso madama la notte ti chiama" – "If the Countess should call you during the night"). She is bothered by its proximity to the Count's chambers: it seems he has been making advances toward her and plans on exercising his droit du seigneur, the purported feudal right of a lord to bed a servant girl on her wedding night before her husband can sleep with her. The Count had the right abolished when he married Rosina, but he now wants to reinstate it. The Countess rings for Susanna and she rushes off to answer. Figaro, confident in his own resourcefulness, resolves to outwit the Count (Cavatina: "Se vuol ballare signor contino" – "If you want to dance, sir count").
Figaro departs, and Dr. Bartolo arrives with Marcellina, his old housekeeper. Figaro had previously borrowed a large sum of money from her, and, in lieu of collateral, had promised to marry her if unable to repay at the appointed time; she now intends to enforce that promise by suing him. Bartolo, seeking revenge against Figaro for having facilitated the union of the Count and Rosina (in The Barber of Seville), agrees to represent Marcellina pro bono, and assures her, in comical lawyer-speak, that he can win the case for her (aria: "La vendetta" – "Vengeance").
Bartolo departs, Susanna returns, and Marcellina and Susanna exchange very politely delivered sarcastic insults (duet: "Via resti servita, madama brillante" – "After you, brilliant madam"). Susanna triumphs in the exchange by congratulating her rival on her impressive age. The older woman departs in a fury.
Cherubino then arrives and, after describing his emerging infatuation with all women, particularly with his "beautiful godmother" the Countess (aria: "Non so più cosa son" – "I don't know anymore what I am"), asks for Susanna's aid with the Count. It seems the Count is angry with Cherubino's amorous ways, having discovered him with the gardener's daughter, Barbarina, and plans to punish him. Cherubino wants Susanna to ask the Countess to intercede on his behalf. When the Count appears, Cherubino hides behind a chair, not wanting to be seen alone with Susanna. The Count uses the opportunity of finding Susanna alone to step up his demands for favours from her, including financial inducements to sell herself to him. As Basilio, the music teacher, arrives, the Count, not wanting to be caught alone with Susanna, hides behind the chair. Cherubino leaves that hiding place just in time, and jumps onto the chair while Susanna scrambles to cover him with a dress.
When Basilio starts to gossip about Cherubino's obvious attraction to the Countess, the Count angrily leaps from his hiding place (terzetto: "Cosa sento!" – "What do I hear!"). He disparages the "absent" page's incessant flirting and describes how he caught him with Barbarina under the kitchen table. As he lifts the dress from the chair to illustrate how he lifted the tablecloth to expose Cherubino, he finds ... the self same Cherubino! The count is furious, but is reminded that the page overheard the Count's advances on Susanna, something that the Count wants to keep from the Countess. The young man is ultimately saved from punishment by the entrance of the peasants of the Count's estate, a preemptive attempt by Figaro to commit the Count to a formal gesture symbolizing his promise that Susanna would enter into the marriage unsullied. The Count evades Figaro's plan by postponing the gesture. The Count says that he forgives Cherubino, but he dispatches him to his own regiment in Seville for army duty, effective immediately. Figaro gives Cherubino mocking advice about his new, harsh, military life from which all luxury, and especially women, will be totally excluded (aria: "Non più andrai" – "No more gallivanting").
Act 2
A handsome room with an alcove, a dressing room on the left, a door in the background (leading to the servants' quarters) and a window at the side.
The Countess laments her husband's infidelity (aria: "Porgi, amor, qualche ristoro" – "Grant, love, some comfort"). Susanna comes in to prepare the Countess for the day. She responds to the Countess's questions by telling her that the Count is not trying to seduce her; he is merely offering her a monetary contract in return for her affection. Figaro enters and explains his plan to distract the Count with anonymous letters warning him of adulterers. He has already sent one to the Count (via Basilio) that indicates that the Countess has a rendezvous of her own that evening. They hope that the Count will be too busy looking for imaginary adulterers to interfere with Figaro and Susanna's wedding. Figaro additionally advises the Countess to keep Cherubino around. She should dress him up as a girl and lure the Count into an illicit rendezvous where he can be caught red-handed. Figaro leaves.
Cherubino arrives, sent in by Figaro and eager to co-operate. Susanna urges him to sing the song he wrote for the Countess (aria: "Voi che sapete che cosa è amor" – "You ladies who know what love is, is it what I'm suffering from?"). After the song, the Countess, seeing Cherubino's military commission, notices that the Count was in such a hurry that he forgot to seal it with his signet ring (which would be necessary to make it an official document).
Susanna and the Countess then begin with their plan. Susanna takes off Cherubino's cloak, and she begins to comb his hair and teach him to behave and walk like a woman (aria of Susanna: "Venite, inginocchiatevi" – "Come, kneel down before me"). Then she leaves the room through a door at the back to get the dress for Cherubino, taking his cloak with her.
While the Countess and Cherubino are waiting for Susanna to come back, they suddenly hear the Count arriving. Cherubino hides in the closet. The Count demands to be allowed into the room and the Countess reluctantly unlocks the door. The Count enters and hears a noise from the closet. He tries to open it, but it is locked. The Countess tells him it is only Susanna, trying on her wedding dress. At this moment, Susanna re-enters unobserved, quickly realizes what's going on, and hides behind a couch (Trio: "Susanna, or via, sortite" – "Susanna, come out!"). The Count shouts for her to identify herself by her voice, but the Countess orders her to be silent. Furious and suspicious, the Count leaves, with the Countess, in search of tools to force the closet door open. As they leave, he locks all the bedroom doors to prevent the intruder from escaping. Cherubino and Susanna emerge from their hiding places, and Cherubino escapes by jumping through the window into the garden. Susanna then takes Cherubino's former place in the closet, vowing to make the Count look foolish (duet: "Aprite, presto, aprite" – "Open the door, quickly!").
The Count and Countess return. The Countess, thinking herself trapped, desperately admits that Cherubino is hidden in the closet. The enraged Count draws his sword, promising to kill Cherubino on the spot, but when the door is opened, they both find to their astonishment only Susanna (Finale: "Esci omai, garzon malnato" – "Come out of there, you ill-born boy!"). The Count demands an explanation; the Countess tells him it is a practical joke, to test his trust in her. Shamed by his jealousy, the Count begs for forgiveness. When the Count presses about the anonymous letter, Susanna and the Countess reveal that the letter was written by Figaro, and then delivered by Basilio. Figaro then arrives and tries to start the wedding festivities, but the Count berates him with questions about the anonymous note. Just as the Count is starting to run out of questions, Antonio the gardener arrives, complaining that a man has jumped out of the window and damaged his carnations while running away. Antonio adds that he tentatively identified the running man as Cherubino, but Figaro claims it was he himself who jumped out of the window, and pretends to have injured his foot while landing. Figaro, Susanna, and the Countess attempt to discredit Antonio as a chronic drunkard whose constant inebriation makes him unreliable and prone to fantasy, but Antonio brings forward a paper which, he says, was dropped by the escaping man. The Count orders Figaro to prove he was the jumper by identifying the paper (which is, in fact, Cherubino's appointment to the army). Figaro is at a loss, but Susanna and the Countess manage to signal the correct answers, and Figaro triumphantly identifies the document. His victory is, however, short-lived: Marcellina, Bartolo, and Basilio enter, bringing charges against Figaro and demanding that he honor his contract to marry Marcellina, since he cannot repay her loan. The Count happily postpones the wedding in order to investigate the charge.
Act 3
A rich hall, with two thrones, prepared for the wedding ceremony.
The Count mulls over the confusing situation. At the urging of the Countess, Susanna enters and gives a false promise to meet the Count later that night in the garden (duet: "Crudel! perchè finora" – "Cruel girl, why did you make me wait so long"). As Susanna leaves, the Count overhears her telling Figaro that he has already won the case. Realizing that he is being tricked (recitative and aria: "Hai già vinta la causa! ... Vedrò, mentr'io sospiro" – "You've already won the case!" ... "Shall I, while sighing, see"), he resolves to punish Figaro by forcing him to marry Marcellina.
Figaro's hearing follows, and the Count's judgment is that Figaro must marry Marcellina. Figaro argues that he cannot get married without his parents' permission, and that he does not know who his parents are, because he was stolen from them when he was a baby. The ensuing discussion reveals that Figaro is Rafaello, the long-lost illegitimate son of Bartolo and Marcellina. A touching scene of reconciliation occurs. During the celebrations, Susanna enters with a payment to release Figaro from his debt to Marcellina. Seeing Figaro and Marcellina in celebration together, Susanna mistakenly believes that Figaro now prefers Marcellina to her. She has a tantrum and slaps Figaro's face. Marcellina explains, and Susanna, realizing her mistake, joins the celebration. Bartolo, overcome with emotion, agrees to marry Marcellina that evening in a double wedding (sextet: "Riconosci in questo amplesso" – "Recognize in this embrace").
All leave, before Barbarina, Antonio's daughter, invites Cherubino back to her house so they can disguise him as a girl. The Countess, alone, ponders the loss of her happiness (aria: "Dove sono i bei momenti" – "Where are they, the beautiful moments"). Meanwhile, Antonio informs the Count that Cherubino is not in Seville, but in fact at his house. Susanna enters and updates her mistress regarding the plan to trap the Count. The Countess dictates a love letter for Susanna to send to the Count, which suggests that he meet her (Susanna) that night, "under the pines". The letter instructs the Count to return the pin which fastens the letter (duet: "Sull'aria...che soave zeffiretto" – "On the breeze... What a gentle little zephyr").
A chorus of young peasants, among them Cherubino disguised as a girl, arrives to serenade the Countess. The Count arrives with Antonio and, discovering the page, is enraged. His anger is quickly dispelled by Barbarina, who publicly recalls that he had once offered to give her anything she wants in exchange for certain favors, and asks for Cherubino's hand in marriage. Thoroughly embarrassed, the Count allows Cherubino to stay.
The act closes with the double wedding, during the course of which Susanna delivers her letter to the Count (Finale: "Ecco la marcia" – "Here is the procession"). Figaro watches the Count prick his finger on the pin, and laughs, unaware that the love-note is an invitation for the Count to tryst with Figaro's own bride Susanna. As the curtain drops, the two newlywed couples rejoice.
Act 4
The garden, with two pavilions. Night.
Following the directions in the letter, the Count has sent the pin back to Susanna, giving it to Barbarina. However, Barbarina has lost it (aria: "L'ho perduta, me meschina" – "I have lost it, poor me"). Figaro and Marcellina see Barbarina, and Figaro asks her what she is doing. When he hears the pin is Susanna's, he is overcome with jealousy, especially as he recognises the pin to be the one that fastened the letter to the Count. Thinking that Susanna is meeting the Count behind his back, Figaro complains to his mother, and swears to be avenged on the Count and Susanna, and on all unfaithful wives. Marcellina urges caution, but Figaro will not listen. Figaro rushes off, and Marcellina resolves to inform Susanna of Figaro's intentions. Marcellina sings an aria lamenting that male and female wild beasts get along with each other, but rational humans can't (aria: "Il capro e la capretta" – "The billy-goat and the she-goat"). (This aria and Basilio's ensuing aria are usually omitted from performances due to their relative unimportance, both musically and dramatically; however, some recordings include them.)
Motivated by jealousy, Figaro tells Bartolo and Basilio to come to his aid when he gives the signal. Basilio comments on Figaro's foolishness and claims he was once as frivolous as Figaro was. He tells a tale of how he was given common sense by "Donna Flemma" ("Dame Prudence") and learned the importance of not crossing powerful people. (aria: "In quegli anni" – "In those years"). They exit, leaving Figaro alone. Figaro muses bitterly on the inconstancy of women (recitative and aria: "Tutto è disposto ... Aprite un po' quegli occhi" – "Everything is ready ... Open those eyes a little"). Susanna and the Countess arrive, each dressed in the other's clothes. Marcellina is with them, having informed Susanna of Figaro's suspicions and plans. After they discuss the plan, Marcellina and the Countess leave, and Susanna teases Figaro by singing a love song to her beloved within Figaro's hearing (aria: "Deh vieni, non tardar" – "Oh come, don't delay"). Figaro is hiding behind a bush and, thinking the song is for the Count, becomes increasingly jealous.
The Countess arrives in Susanna's dress. Cherubino shows up and starts teasing "Susanna" (really the Countess), endangering the plan. (Finale: "Pian pianin le andrò più presso" - "Softly, softly I'll approach her") The Count gets rid of him by striking out in the dark. His punch actually ends up hitting Figaro, but the point is made and Cherubino runs off.
The Count now begins making earnest love to "Susanna" (really the Countess), and gives her a jeweled ring. They go offstage together, where the Countess dodges him, hiding in the dark. Onstage, meanwhile, the real Susanna enters, wearing the Countess' clothes. Figaro mistakes her for the real Countess, and starts to tell her of the Count's intentions, but he suddenly recognizes his bride in disguise. He plays along with the joke by pretending to be in love with "my lady", and inviting her to make love right then and there. Susanna, fooled, loses her temper and slaps him many times. Figaro finally lets on that he has recognized Susanna's voice, and they make peace, resolving to conclude the comedy together ("Pace, pace, mio dolce tesoro" - "Peace, peace, my sweet treasure").
The Count, unable to find "Susanna", enters frustrated. Figaro gets his attention by loudly declaring his love for "the Countess" (really Susanna). The enraged Count calls for his people and for weapons: his servant is seducing his wife. (Ultima scena: "Gente, gente, all'armi, all'armi" – "Gentlemen, to arms!") Bartolo, Basilio and Antonio enter with torches as, one by one, the Count drags out Cherubino, Barbarina, Marcellina and the "Countess" from behind the pavilion.
All beg him to forgive Figaro and the "Countess", but he loudly refuses, repeating "no" at the top of his voice, until finally the real Countess re-enters and reveals her true identity. The Count, seeing the ring he had given her, realizes that the supposed Susanna he was trying to seduce was actually his wife. Ashamed and remorseful, he kneels and pleads for forgiveness himself ("Contessa perdono!" – "Countess, forgive me!"). The Countess, more kind than he ("Più docile io sono" – "I am more mild"), forgives her husband and all are contented.

Place: Seville, Spain
Time: 18th century
Act 1
The square in front of Bartolo's house
In a public square outside Bartolo's house a band of musicians and a poor student named Lindoro are serenading, to no avail, the window of Rosina ("Ecco, ridente in cielo"; "There, laughing in the sky"). Lindoro, who is really the young Count Almaviva in disguise, hopes to make the beautiful Rosina love him for himself – not his money. Almaviva pays off the musicians who then depart, leaving him to brood alone. Rosina is the young ward of the grumpy, elderly Bartolo and she is allowed very little freedom because Bartolo plans to marry her once she is of age and thus appropriate her not inconsiderable dowry.
Figaro approaches singing (Aria: "Largo al factotum della città"; "Make way for the factotum of the city"). Since Figaro used to be a servant of the Count, the Count asks him for assistance in helping him meet Rosina, offering him money should he be successful in arranging this. (Duet: "All'idea di quel metallo"; "At the idea of that metal"). Figaro advises the Count to disguise himself as a drunken soldier, ordered to be billeted with Bartolo, so as to gain entrance to the house. For this suggestion, Figaro is richly rewarded.
A room in Bartolo's house with four doors
The scene begins with Rosina's cavatina, "Una voce poco fa" ("A voice a little while ago"). (This aria was originally written in the key of E major, but it is sometimes transposed a semitone up into F major for coloratura sopranos to perform, giving them the chance to sing extra, almost traditional, cadenzas, sometimes reaching high Ds or even Fs.)
Knowing the Count only as Lindoro, Rosina writes to him. As she is leaving the room, Bartolo and Basilio enter. Bartolo is suspicious of the Count, and Basilio advises that he be put out of the way by creating false rumours about him (this aria, "La calunnia è un venticello" – "Calumny is a little breeze" – is almost always sung a tone lower than the original D major).
When the two have gone, Rosina and Figaro enter. Figaro asks Rosina to write a few encouraging words to Lindoro, which she has actually already written. (Duet: "Dunque io son...tu non m'inganni?"; "Then I'm the one...you're not fooling me?"). Although surprised by Bartolo, Rosina manages to fool him, but he remains suspicious. (Aria: "A un dottor della mia sorte"; "To a doctor of my class").
Count Almaviva, disguised as a soldier and pretending to be drunk, enters the house and demands to be quartered there. In fear of the drunken man, Berta the housekeeper rushes to Bartolo for protection. Bartolo tells the "soldier" that he (Bartolo) has an official exemption which excuses him from the requirement to quarter soldiers in his home. Almaviva pretends to be too drunk and belligerent to understand, and dares Bartolo to brawl. While Bartolo searches his cluttered desk for the official document which would prove his exemption, Almaviva whispers to Rosina that he is Lindoro in disguise, and passes a love-letter to her. Bartolo suspiciously demands to know what is in the piece of paper in Rosina's hands, but she fools him by handing over her laundry list. Bartolo and the Count argue loudly. Basilio enters; then Figaro, who warns that the noise of the argument is rousing the whole neighborhood. Finally, the noise attracts the attention of the Officer of the Watch and his troops, who crowd into the room. Bartolo demands that the Officer arrest the "drunken soldier". The Officer starts to do so, but Almaviva quietly reveals his true identity to the Officer, and he (the Officer) backs off and stands down. Bartolo and Basilio are astonished and mystified; Figaro laughs quietly at them. (Finale: "Fredda ed immobile, come una statua"; "Cold and still, just like a statue"). The confusion intensifies and causes everyone to suffer headaches and auditory hallucinations ("Mi par d'esser con la testa in un'orrida fucina; dell'incudini sonore l'importuno strepitar."; "My head seems to be in a fiery forge: the sound of the anvils deafens the ear.")
Act 2
A room in Bartolo's house with a piano
Almaviva again appears at the doctor's house, this time disguised as a priest who is also a singing tutor and pretending to act as substitute for the supposedly ailing Basilio, Rosina's regular singing teacher. Initially, Bartolo is suspicious, but does allow Almaviva to enter when the Count gives him Rosina's letter. He describes his plan to discredit Lindoro whom he believes to be one of the Count's servants, intent on pursuing women for his master. While Almaviva pretends to give Rosina her singing lesson, Figaro arrives to shave Bartolo. Bartolo demurs, but Figaro makes such a scene he agrees, but in order not to leave the supposed music master alone with Rosina, the doctor has Figaro shave him right there in the music room. When Basilio suddenly appears, he is bribed by a full purse from Almaviva and persuaded to leave again, with much discussion of how ill he looks. (Quintet: "Don Basilio! – Cosa veggo!"; "Don Basilio! – What do I see?"). Figaro begins to shave Bartolo, but Bartolo overhears the lovers conspiring, and angrily drives everybody away.
The scene returns to the location of act 1 with a grill looking out onto the square. Bartolo orders Basilio to have the notary ready to marry him to Rosina that evening. He also explains his plot to come between the lovers. Basilio leaves and Rosina arrives. Bartolo shows Rosina the letter she wrote to "Lindoro", and persuades her that this is evidence that Lindoro is merely a flunky of Almaviva and is toying with her at Almaviva's behest. Rosina believes him and agrees to marry him.
During an instrumental interlude, the music creates a thunder storm to indicate the passage of time. The Count and Figaro climb up a ladder to the balcony and enter the room through a window. Rosina shows Almaviva the letter and accuses him of betraying her. Almaviva reveals his identity and the two reconcile. While Almaviva and Rosina are enraptured by one another, Figaro keeps urging them to leave. Two people are heard approaching the front door, who later turn out to be Basilio and the notary. However, when the Count, Rosina, and Figaro attempt to leave by way of the ladder, they discover it has been removed. The marriage contract requires two witnesses; Figaro is one, but another is needed. The Count makes Basilio an offer he can't refuse: the choice of accepting a bribe and being a witness to his marriage or receiving two bullets in the head (an easy choice, Basilio says). He and Figaro witness the signatures to a marriage contract between the Count and Rosina. Bartolo barges in, accompanied by the Officer and the men of the watch, but too late; the marriage is already complete. The befuddled Bartolo (who was the one who had removed the ladder) is pacified by being allowed to retain Rosina's dowry. The opera concludes with an anthem to love ("Amor e fede eterna, si vegga in noi regnar!").
