[[TheOneWith The opera with]] the SadClown.

A cornerstone of Italian ''verismo'' ("reality") opera, ''Pagliacci'' is composer Ruggiero Leoncavallo's first opera, and his [[OneHitWonder only one]] still regularly performed nowadays. Traditionally, before the opera opens, the hunchback clown Tonio delivers a lengthy prologue: don't treat us as make-believe; we are people of flesh and blood, and [[TrueArtIsAngsty art is created with real love and real tears]].

The story revolves around a clown, Canio. One day, Canio's troupe of ''CommediaDellArte'' comes to town, and will put on the peoples' favorite show that evening. When the rest of the troupe go away for a drink, Canio sits by himself, musing how he will not allow himself to be cuckolded and humiliated like Pagliaccio, the character he will be playing. Meanwhile, his wife Nedda worries that Canio may find out about her little secret, and her discomfort deepens with the appearance of Tonio, who professes his love. Nedda spurns his advance and mocks at his ugly appearance. Tonio [[AttemptedRape tries to force himself onto Nedda]], but she grabs a whip and strikes him. Tonio swears vengeance.

As Tonio leaves, the villager Silvio, Nedda's sweet-talking darling, comes by. He urges her to elope that night; she is ambivalent. The two share a tender moment together. Of course, Tonio sees all these - and he drags Canio in just in time.

Furious, Canio demands the name of the guy, but Nedda refuses to speak. Other actors urge Canio to calm down.

In front of a large audience during the play - which involves how Colombina (played by Nedda), under the knowing eyes of her servant Taddeo (Tonio), slips a sleeping drought in Pagliaccio's (Canio's) wine so that she can elope with her lover Arlecchino (Peppe, the fourth member of the troupe) - Canio derails the comedy to demand that Nedda comes clean. The crowd marvel at how emotive the performance is, but Nedda knows she is in [[OhCrap deep trouble]]. She desperately tries to keep the play on track, which only fuels Canio's anger. He stabs Nedda on stage. Her dying scream gives away the name of her lover, whom Canio then kills. His vengeance done, Canio [[note]]In some stagings, and in the original version of the script, the line is given to Tonio, forming a FramingDevice[[/note]] announces "La Commedia è finita!" - "The comedy is finished!"

!Tropes found in ''Pagliacci''

* AllPartOfTheShow: The audience initially reacts with delight at how genuine Pagliaccio's performance is until he becomes progressively unhinged and they realize he's ''not'' acting.
* BasedOnAGreatBigLie: Leoncavallo claimed the opera was based on a real case that his father dealt with, but there is no corroborating evidence whatsoever.
* BSODSong: ''Vesti la giubba'', as Canio is wrought with turmoil over how to process his wife's infidelity while still having to prepare for their performance.
* TheChessmaster: Tonio manages to manipulate the others into doing what he wants to destroy their own lives without having to get his own hands dirty.
* CrystalBallScheduling: It works out very badly that Canio and Nedda are slated to play in a comedy about an unfaithful wife and jealous husband.
* {{Cuckold}}: Nedda is cheating on Canio with Silvio.
* DespairEventHorizon: In most performances, at the end of ''Vesti la giubba'', Canio breaks down sobbing.
* DramaticIrony: In universe, the roles in the performance on this night have deadly consequences when Nedda's character says goodbye to her character's lover in the same way the real Nedda did to her real adulterous lover. Having a real life husband and wife with an affair going on play a husband and wife with an affair has never been so deadly.
* EvilSoundsDeep: Tonio, a baritone role.
* GreenEyedMonster: Tonio, who makes advances on a married woman and, failing that, makes sure that his victim's life is ruined.
* HostilityOnTheSet: Invoked with the ShowWithinAShow, finally leading Canio to snap.
* IfICantHaveYou: The stance of both Tonio and Canio towards Nedda.
* IronicEcho: Nedda's character says goodbye to her lover in the play with the same phrase Canio heard her use to her lover in real life.
* KarmaHoudini: In the 1994 staging with Luciano Pavarotti as Canio, immediately after the closing line, the camera turns to Tonio on the stage, laughing his head off. His schemes to ruin everyone who wronged him came off perfectly.
* ManipulativeBastard: Tonio plays on everyone's emotions and ultimately succeeds into getting all his rivals to get revenge on each other for him. In most productions he even slips the knife into Canio's hand at an opportune moment.
* MonsterClown:
** UnbuiltTrope with Canio. It's still meant to be taken as ironic and frightening that Canio is depressed and homicidal ''despite'' being a clown.
** Played closer to a straight version with Tonio, a clown who is also an [[AttemptedRape attempted rapist]] and all-around ManipulativeBastard.
* NoFourthWall: A frightening, in-story example, as it concludes with Silvio trying to come to Nedda's aid when Canio stabs her, only to be fatally stabbed himself.
* NonIronicClown: ZigZagged. DramaticIrony arises from the fact that Canio is engaged to play his clown role non-ironically, which ultimately he isn't able to do because he's a SadClown, leading him to snap and commit a double murder more like a MonsterClown.
* PlotParallel: See ShowWithinAShow.
* PopCulturalOsmosis: You've heard ''[[https://youtu.be/Z0PMq4XGtZ4?t=1m56s Vesti la Giubba]]'' before. Also, this play is a favorite theme for SelfDemonstrating/TheJoker for his crimes.
** The Penguinís favorite opera is Pagliacci. While the story of killer clown also appeals to the above rogue, Pagliacci is the story of a man betrayed by the woman he loves who then flies into a murderous rage when confronted by the truth. [[DisproportionateRetribution No wonder]] Mr. [[{{Yandere}} Cobblepot]] canít help singing along.
** The matching notes of the lyrics, "Ridi, Pagliaccio, sul tuo amore infranto! (Laugh, clown, at your broken love!)" were invoked by Music/{{Queen}} in the opening of their 1984 song, "It's A Hard Life".
* SadClown: Pagliaccio serves as the TropeCodifier.
* TheShowMustGoOn: This trope is invoked to provide the first act climax, as Canio has ''just'' discovered his wife's infidelity - but is told to get ready for their show, as the troupe can't afford to disappoint the customers.
* ShowWithinAShow: Canio's and Nedda's performance is layered with DramaticIrony due to the plot being nigh-identical to their "real-life" troubles.
* {{Yandere}}: Canio is driven to murder Nedda over her infidelity.
* YourCheatingHeart: Nedda is having an affair behind her husband's back.
