L’oca del Cairo (K. 422) — Mozart’s Unfinished Opera Buffa Fragment (1783)
av Wolfgang Amadeus Mozart
L’oca del Cairo (K. 422) is an unfinished Italian opera buffa fragment that Mozart began in July 1783 and set aside later the same year, leaving only portions of Act I. Written at age 27 between Salzburg and Vienna, it offers a revealing glimpse of his comic-operatic workshop on the road toward the mature Da Ponte operas.
What Is Known
Mozart began L’oca del Cairo (K. 422) in July 1783 and abandoned the project after composing a substantial run of numbers for Act I; the surviving music amounts to roughly three quarters of that act (about 45 minutes in performance) plus some recitative and at least one further sketch.[1] The libretto is in Italian and is by Giambattista Varesco (also Mozart’s librettist for Idomeneo).[1]

The Digitale Mozart-Edition preserves the surviving sung text and confirms that the extant portion closes with a clear “Fine dell’atto primo.”[2] In modern usage, the fragment is often heard in concert selections or within later completions/arrangements that supply missing portions of the drama.[1]
Musical Content
What survives is, above all, Mozart thinking theatrically in ensembles. The extant pages include quick-fire comic exchanges (for example, an early Allegro assai duet for Chichibio and Auretta) and larger multi-voice numbers that propel stage action through overlapping text rather than through stand-alone display.[2]
In the Act I scenes that survive, Mozart alternates patter-like buffa motion with more lyrical pleas for “libertà” (freedom), then gathers the principals into a concerted close—exactly the kind of finale-craft that would become a hallmark of his later Viennese comic operas.[2] Even in fragmentary form, L’oca del Cairo shows Mozart in 1783 testing how far comedic characterization can be carried by ensemble texture and rapid pacing, not merely by individual arias.
