The music comes from Pirates of the Caribbean, the Disney film series that began with The Curse of the Black Pearl in 2003, and its best-known theme is often called He's a Pirate. Written for swashbuckling adventure, the melody quickly became shorthand for pirates, treasure and daring escapes far beyond the films themselves. It spread through trailers, theme parks, covers and online videos, where short clips are reused for reveals, entrances and jokes. Its lasting appeal lies in that instant recognition: a few notes are enough to set a playful, high-stakes mood.
