Count Almaviva again appears at the doctor's house, this time disguised as Don Alonso, a priest and singing tutor who is substituting for the supposedly ailing Basilio. To gain Bartolo's trust, Don Alonso tells him he has intercepted a note from Lindoro to Rosina, and says that Lindoro is a servant of Count Almaviva who has dishonorable intentions towards Rosina. While Almaviva pretends to give Rosina her singing lesson ("Contro un cor"; "Against a heart"), Figaro arrives to shave Bartolo. Not wanting to leave Rosina alone with the singing teacher, Bartolo insists Figaro shave him right there in the music room. Basilio suddenly appears for his scheduled music lesson, but 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?"). Bartolo overhears the lovers conspiring, and angrily drives everybody away.
