Don Bucefalo
Music master Don Bucefalo offers singing lessons to villagers. Rosa, believing her husband Carlino died in war, hopes to study singing and marry Count Belprato; her neighbour Don Marco also loves her. Carlino returns disguised as a soldier to find out whether Rosa still loves him. While Don Bucefalo prepares a village opera, Carlino insults Rosa and sets off accusations. Don Marco eventually funds the production and sings its principal bass role. During rehearsals, Carlino reveals himself and reunites with Rosa; all ends happily.
