Sull'aria ... che soave zeffiretto

"Sull'aria ... che soave zeffiretto" (On the breeze ... What a gentle little Zephyr) is a duettino, or a short duet, from act 3, scene X, of Wolfgang Amadeus Mozart's 1786 opera The Marriage of Figaro, K. 492, to a libretto by Lorenzo Da Ponte.

[1] Its time signature is 6/8, its key is B-flat major, and it is 62 bars long; the tempo indication is allegretto.

In the second part, Contessa and Susanna read alternate lines slightly overlapping (bars 38–45) until they finish in a true duet with their conclusion.

Without repetitions, the text is: "Canzonetta sull'aria" Che soave zeffiretto Questa sera spirerà Sotto i pini del boschetto.

"[2] This is ironic as the opera characters are singing about a duplicitous love letter to expose infidelity, and Dufresne's wife's affair is the event which indirectly leads to his imprisonment.
