Pirate Music

Ok, so the guy I'm writing the japanese score for has this old pirate film he made . He never actually got music written for it so he asked me to try my hand at it. But once again, I have no idea what this consists of. I can get a good idea from listening to the pirates of the Caribbean soundtrack, but since I got such a good response on my Oriental Music thread (which helped a lot, thanks again for the help there) I figured why not just throw this one out there too? So, advice? tips? instruments used? Chords and scales?

Again, thanks in advance.

Just listen to that.:P

And I'm sure the man himself will be along to give you a few tips...:P
