History YMMV / CosiFanTutte

* ValuesDissonance

* CutSong: During rehearsals, Mozart cut Guiglielmo's long, showy Act 1 aria "Rivolgete a lui lo sguardo" and replaced it with a much shorter aria. "Rivolgete" was published separately, and some productions put it back into the opera for singers who want a ShowStopper.

* AlternateCharacterInterpretation: Lots of them. Is Alfonso a StrawMisogynist or an enlightened man trying to cure both the men and women of their romantic illusions? Do the women actually fall in love with the men in disguise (and vice-versa) or are they still in love with the people they were originally engaged to? Does Despina actually believe that AllMenArePerverts or is she just saying that to tempt her employers into cheating on their boyfriends? Plus there's the AmbiguousEnding which leaves it completely open as to what choices the characters make in the end.
* SugarWiki/AwesomeMusic: The quartet ''Alla bella Despinetta'' starts the section and then the sisters join in.

* FamilyUnfriendlyAesop:
** Guys, all girls turn into sluts if you don't pay them enough attention. [[ImAManICantHelpIt They're women, they can't help it]]: AllWomenAreLustful.
** Alternately... it's unfair for men to expect women to stick to just one man, since [[ImAManICantHelpIt no one expects that of men]]. Monogamy is unrealistic and you're better off the sooner you learn that. If the characters of half of the tragic operas had heard Despina's advice, they could have survived (e.g. Otello, Tosca, [[Theatre/{{Carmen}} Don Jose]]...)

** The trio "Soave sia il vento" is famous as one of Mozart's most beautiful ensemble numbers, with a gentle accompaniment under two soprano voices and Alfonso's bass line. Like the similar duet from ''Le Nozze di Figaro'', it became known to a wider audience through its use in a film, Creator/JohnSchlesinger's ''Film/SundayBloodySunday''.

* VindicatedByHistory: The opera's cynicism and its AllWomenAreLustful attitude gave it a very bad reputation in the Romantic era, leading it to be mostly unperformed for over a century after Mozart's death despite the acknowledged excellence of the music. In the 20th century it was successfully revived again and soon became part of the standard operatic repertoire, with many performances and recordings.

* CrowningMomentOfAwesome: Despina, the snarky, world-wise maid who laughs at the dramatic notions of love her mistresses have, is always ready for a laugh and takes everything in stride. ''Una donna a quindici anni'' is probably the best example; the music even swells up into a crescendo when she tells them to do as she says to reign like a queen with "you could" and "I'd like".
* CrowningMomentOfFunny
--> '''Dorabella''': Our fiances have left for war!
--> '''Despina''': So much the better for them: You'll see them return crowned with laurel.
--> '''Fiordiligi''': But they might be killed!
--> '''Despina''': Why then, so much the better for you!
