Così fan tutte means “so do they all,” with tutte (all) in the feminine. What is it that they all do? Don Alfonso, the cynical baritone who organizes the practical joke that forms the plot of the opera, thinks he knows what all women do: they are fickle. To prove his point, he persuades the heroes of the opera, Ferrando and Guglielmo, to leave their fiancées, return in disguise, and steal the hearts of Dorabella and Fiordiligi away from the men they are engaged to marry. But will they be true to their fiancées or will they be wooed away by the handsome “strangers”?

Sung in English with English surtitles projected above the stage.
