We continue to listen to the Pirates of the Caribbean Swashbuckling Songs (over and over...my son says, "We've listened to the pirates CD sixteen times!" but I think he's off by a factor of ten...). There's this great, ponderous pipe-organ song, and it got me wondering where the connection between pirates and pipe organs comes from.
Alas, Google has not answered my question. The closest I could come to an answer is the suggestion that the connection between the movie's Davy Jones and an organ is a tip of the hat to Jules Verne's 20,000 Leagues Under the Sea, where Captain Nemo has an organ on the Nautilus. The problem with that, though, is that I remember cartoons having the same trope of pipe organs on sunken ships and shipwrecks. Even Goonies has it, doesn't it? A booby-trapped pipe organ? So if the connection is to Verne, then it goes back much further, and the movie is only continuing that earlier trope.
Unless...hmmm. The movie is loosely based on the amusement park ride. I have no idea how old that ride is or if it has the same Davy Jones/Flying Dutchman character. But if the ride is old enough and has a pipe organ (as a nod to Verne), then that could be the source of the trope. Lauren, you know all about Disney World. Come to my rescue here. Or anyone else with knowledge about such things, of course.
