who had sung Rosina in the 1818 London premiere, and sang the new aria c. 1820 at the Théâtre-Italien in Paris, where it was published. The singing lesson in act 2 has often been turned into "a show-stopping cabaret". Adelina Patti was known to include Luigi Arditi's "Il bacio", the Bolero from Verdi's I vespri siciliani, the Shadow Song from Meyerbeer's Dinorah, and Henry Bishop's "Home! Sweet Home!". Nellie Melba followed suit, accompanying herself on the piano in the final song. Pauline Viardot began the practice of inserting Alexander Alyabyev's "Nightingale". In a recording of a La Scala performance in 1956, Maria Callas sang a shortened version "Contro un cor", transposed up a tone, in E. Once after Patti had sung a particularly florid rendition of the opera's legitimate aria, "Una voce poco fa", Rossini is reported to have asked her: "Very nice, my dear, and who wrote the piece you have just performed?" The piece is a staple of the operatic repertoire Because of a scarcity of true contraltos, the role of Rosina has most frequently been sung by a coloratura mezzo-soprano (with or without pitch alterations, depending on the singer), and has in the past, and occasionally in more recent times, been sung by coloratura sopranos such as Marcella Sembrich, Maria Callas, Roberta Peters, Gianna D'Angelo, Victoria de los Ángeles, Beverly Sills, Lily Pons, Diana Damrau, Edita Gruberová, Kathleen Battle and Luciana Serra.

Famous contralto Rosinas include Ewa Podleś who made her stage debut in that role.

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.
