カイロの鵞鳥

L'oca del Cairo is an incomplete Italian opera buffa in three acts, begun by Wolfgang Amadeus Mozart in July 1783 but abandoned in October. The complete libretto by Giambattista Varesco remains. Mozart composed seven of the ten numbers of the first act, plus some recitative, as well a sketch for a further aria; the extant music amounts to about 45 minutes.
