Carmina Burana is a cantata by German composer Carl Orff, first performed in 1937, based on medieval poems. The section most people recognize online is O Fortuna, whose huge choir and orchestral opening became a shorthand for extreme drama in film, trailers and internet edits. Because the music sounds instantly serious and overwhelming, creators keep using it to turn small moments into exaggerated high-stakes scenes, both sincerely and as parody.
