Timpani rolls and cymbal crashes come from orchestral and stage percussion, where drumrolls have long signalled that an announcement or performance is about to begin. Online, this ten-second version is used as a clean sting for edits, slideshows and parody award moments, often paired in playlists with other dramatic hits like dun dun dunnnnnnnn. Its length lets creators stretch or trim the build to fit their timing, which is why it keeps appearing whenever a reveal needs formality and suspense rather than a joke sound.
