He hires Figaro, a clever barber, to help him get into Dr Bartolo's house, where Rosina is kept under lock and key. Figaro comes up with various schemes to fool Bartolo and his ally Don Basilio, a music teacher. Almaviva pretends to be a drunken soldier, a music teacher and a notary to get close to Rosina. Rosina initially believes him to be Lindoro, but later learns his true identity and agrees to elope with him.
