Multiple Jacks

"Multiple Jacks" is a musical theme composed and conducted by Hans Zimmer for Pirates of the Caribbean: At World's End. It appears as track four on the film's soundtrack, at 3:51 in length.

The track begins with ambient tones and springy-sounding bass elements, along with a low guitar tone, before seguing into a quirky refrain of "Jack Sparrow" on harpsichord and plucked strings (00:39). This refrain is repeated, and leads to a rendition of Jack's introductory theme from "The Medallion Calls" (01:33). Electronic pulses and percussion begin are introduced, gaining in speed until the end of the track.

It underscores the introduction of Jack Sparrow and his multiple personas in Davy Jones' Locker.
