The Marriage of Figaro (play)
The play formed the basis for an opera with a libretto by Lorenzo Da Ponte and music by Mozart, also called "The Marriage of Figaro" (1786). In 1799, another opera based on the same play, "La pazza giornata, ovvero Il matrimonio di Figaro", was produced in Venice with libretto by Gaetano Rossi and music by Marcos Portugal.

"" (On the breeze...What a gentle little Zephyr) is a "duettino", or a short duet, from act 3 of Wolfgang Amadeus Mozart's opera "The Marriage of Figaro", K. 492, to a libretto by Lorenzo Da Ponte. In the duettino, Countess Almaviva (a soprano) dictates to Susanna (also a soprano) the invitation to a tryst addressed to the countess' husband in a plot to expose his infidelity.
