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 the subsequent aria of Basilio are mostly not performed; 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 strikes out in the dark at Cherubino. but his punch hits Figaro, 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
