Rondò for Soprano “Al desio, di chi t’adora” in F major (K. 577)
par Wolfgang Amadeus Mozart
Mozart’s Al desio, di chi t’adora (K. 577) is a stand-alone soprano rondò with orchestra, completed in Vienna in July 1789, that offers an alternative “Susanna aria” for Le nozze di Figaro. Often overlooked beside Figaro’s familiar Act IV serenade, it is a miniature scene of theatrical poise whose distinctive coloring—especially its dark, mellow wind sonorities—shows Mozart still refining his operatic palette at age 33.
Background and Context
Mozart’s Al desio, di chi t’adora belongs to the small but telling group of substitute numbers he wrote for Viennese revivals of his operas—pieces that sit on the border between “opera” and “concert aria.” The Köchel catalogue identifies it explicitly as belonging to Le nozze di Figaro (K. 492), “second version,” and dates it to Vienna, July 1789 [1]. In other words, it is not an abstract salon rondò: it is stage music conceived for a specific, practical theatrical need.

Modern scholarship and performance tradition connect K. 577 to the 1789 Vienna revival of Figaro, in which Susanna’s famous Act IV canzonetta “Deh vieni, non tardar” was replaced by this alternative rondò [2]. That context matters, because K. 577 reframes Susanna’s “waiting in the garden” moment: the emotional temperature becomes less folk-like and intimate, more virtuoso and public-facing—closer to the late-18th-century taste for brilliant prima donna display.
If the piece is not universally famous, that is partly because it is rarely staged in Figaro today: it interrupts a dramatic situation Mozart had already solved perfectly in 1786. Yet precisely because it is an “optional” number, K. 577 has long lived a double life as a concert item—useful to singers, and revealing to listeners as a glimpse of how Mozart could rethink his own theatre.
Text and Composition
The work is a rondò with recitative (Rondò con recitativo), transmitted as part of the Figaro appendix tradition; the Mozarteum’s work entry documents multiple early copies and prints, including a source description that lays out the scoring and identifies it as composed “für Signora Ferrarese” (Adriana Ferraresi del Bene) [1]. Ferrarese’s name appears frequently in discussions of the 1789 revival arias and helps explain the piece’s more elaborate vocal profile.
The authorship of the Italian text is not securely known. Program-note literature often treats Lorenzo Da Ponte (the original Figaro librettist) as a plausible candidate, but cautiously—an attribution best stated as conjectural rather than fact [2]. What can be said with confidence is that the recitative “Giunse alfin il momento” provides a plausible theatrical lead-in to the rondò in concert performance, mirroring the function of Susanna’s original Act IV setup in Figaro [2].
Musical Character
K. 577 is distinctive within Mozart’s soprano scena repertory because of its instrumental color and its hybrid dramatic stance: half inward confession, half operatic display. A source description transmitted via the Mozarteum catalogue lists an especially telling orchestration—two violins, viola and basso, plus two basset horns in C, two bassoons, and two horns in F [1]. The choice of basset horns (with their veiled, clarinet-family warmth) immediately shifts the sound world away from the brighter Figaro serenade style; it points instead toward Mozart’s late fascination with mellow clarinet timbres and their expressive “twilight” shading.
Vocally, the rondò asks for supple cantabile and agile passagework, but its effect is not mere virtuosity. Mozart lets the singer hover between expectancy and urgency—an operatic psychology rendered in phrasing and orchestral response rather than stage action. Heard alongside the better-known Figaro substitutions (such as Susanna’s Act II replacement aria Un moto di gioia, K. 579), K. 577 deserves attention as evidence of Mozart’s continuing experimentation in 1789: even when revisiting old theatre, he was still finding new balances between character, vocal brilliance, and instrumental imagination.
