The melody comes from Pirates of the Caribbean, the swashbuckling film series that began with The Curse of the Black Pearl in 2003, where the rousing theme became closely linked with Captain Jack Sparrow and high-seas adventure. Flute arrangements soon spread online as ringtones, covers and short clips, because the tune is easy to recognise even without an orchestra behind it. It remains popular for pirate jokes, travel videos and playful entrances, keeping the film's adventurous spirit alive in a form anyone can instantly hum.
