I love Act I finales that blend the major songs of the act all into one big epic full-cast number, i.e. One Day More from Les Mis or Man Up from The Book of Mormon.
I also love dark reprises and counterpoint duets. Patter songs are fun, but not in excess.
-Ending a big group song by shouting the title of the song/show. This is so cliched and cheesy it isn't done much anymore... the last time I recall was the 'neon' GREASE revival.
-Ending a big group song, holding the pose for applause, then they break "laughing and scratching."
"What- and quit show business?" - the guy shoveling elephant shit at the circus.

Agree 100%. These numbers never get old - Non Stop from Hamilton is another amazing addition.
This is more a theater trope than a musical theater trope but I love it when a distant, difficult or person finally expresses a moment of tenderness and all of a sudden Everyone Understands All. I thought I was immune to this particular trope until I saw Fun Home and bawled all the way through the curtain calls.
I appreciate a good many, but my number one fave is what the Japanese call tsundere. The "boy and girl meet, hate each other and refuse to budge about it....but involuntarily come to realize the other isn't as bad as they thought and realize they're each others perfect match and right for no one else" ala Pride and Prejudice, Beauty and the Beast, all that good stuff :)
My second fave is "boy and girl meet and like each other and fall harder than they thought, but due to many abounding circumstances can't bring themselves to say it aloud...at all" ala Once. It was actually Once that made me realize what plot devices move my soul.
And of course these two tropes usually work in conjunction with each other, but here and there they don't.
The kind of entr-acte that begins by encoring a great musical-theatrical moment from the first act and stirs the audience's imagination of how that moment might relate to what it is about to see in the second.
The diva 11 o'clock number and dark/sad reprise almost always move me, no matter how many variations of them I've seen.
Also not a trope exclusive to musical theatre, but I love the coming of age and coming out story. A Chorus Line may not have been the first to use this trope, but they certainly brought it into the mainstream. Falsettos was pretty subversive in avoiding this trope, but I have to admit that it still felt just as revolutionary in Fun Home, all these years later.
I also love musicalized arguments- "Heavy" and "It's All Over" from Dreamgirls, "Your Fault" from Into the Woods, and "The Blame" from Titanic come to mind. The drama of it all!
And pretty much every moment of shows like 42nd Street. The chorus girl that has the right stuff, the Busby Berkeley production numbers, the brassy character roles, and the Audition numbers. UGH, and any time "backstage" is shown behind a scrim or with creative staging. I eat that stuff UP.
Someone on the first page mentioned "I Want" songs, which I love too. The best ones tell you a lot about the character and give a hint of what is to come. "Something's Coming," "The Wizard and I," and "Corner of the Sky" are some of my favorites.
The final bars of an overture where they reprise a phrase or two of the hit tune over the top of a hitherto unheard accompaniment - "The Boys From Syracuse" contains a classic example.
I love the full-length overture to "The Producers." Has there been a great overture since then? When the "I Wanna Be a Producer" melody plays at quadruple time as a "travel music" like motif, before emerging in its usual tempo as a suddenly recognizable theme, that's arranging gold to me.
I'm a sucker for "anticipation" songs. Perhaps not as common but they get me PUMPED.
The "Quintet" from WEST SIDE STORY is perhaps the best example. On record I also really enjoy ones like "What A Night This is Going To Be" from BAKER STREET or "A Night We'll Never Forget" from CARRIE though I've never seen the shows. "A Weekend in the Country" especially the latter bits is also a well done example, and "Prima Donna" from PHANTOM.
