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: "" – "Vengeance"). Bartolo departs, Susanna returns, and Marcellina and Susanna exchange very politely delivered sarcastic insults (duet: "" – "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: "" – "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, and offers to pay money if she will submit 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: "" – "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
