Album cover
"Underwater March" is a musical theme credited to Klaus Badelt (with Hans Zimmer's assistance) for Pirates of the Caribbean: The Curse of the Black Pearl. It appears as track thirteen on the film's soundtrack, at 4:12 in length.
Track description[]
The track starts out in a minor key which rises as a dramatic chord (00:15). Woodwinds are heard in the background as a mournful melody begins (00:27), undercut with percussion beats. The music rises triumphantly with a variation of the main swashbuckling theme (01:50). It quietens into a tender rendition of the love theme (02:09), then segues into the cursed crew's theme (03:08) which increases in intensity until a dramatic climax (04:08). It trails off into a segue into "One Last Shot".
In the film[]
The first part of the track underscores the death of Hector Barbossa and the cursed crew's defeat onboard HMS Dauntless, while the second part is heard during the titular "underwater march", which, chronologically, occurs prior to the opening of the track.
