This is kinda old, but it's been nagging me since I first saw it (don't know why I didn't try asking here, just didn't think about it). Now, I don't know if the music is part of the original soundtrack or if it's an old classical piece, so if nobody can figure out I'll just assume it was made for the soundtrack. Here's the trailer. There are multiple trailers in that link and all of them have the song except for the first and third. I'd be grateful if someone named the song.
By the way, I love the series, all three Onimushas.
