The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
For clarification, what is a funeral march? Because the iconic Funeral March (Marche funèbre) that everyone knows was composed by Fryderyk Chopin.
If that's what you are referring to, it and pretty much all other brief uses of Classical Music will be Standard Snippet.
Edited by KDI am referring to the Chopin march in some cases, but in others it is unnamed, for example in literature: "Slowly, he played a funeral march on his violin". It's not so much what the music is, but when a character in-universe plays it.

Is there a trope for when somebody in-universe plays a funeral march, to mark a momentous happening?
