My brother wants me to learn it but i cant just do it by ear :heh: please help
(if you want to hear the song it is on the site tv-links.co.uk go to anime then to blood + it is the episode "First Kiss"

If you are talking about the solo that Hagi always plays, it's the Prelude to Bach's 5th Cello Suite. It's public domain, so you can get it on IMSLP ( http://imslp.org/wiki/Suites_for_Violoncello_Solo,_BWV_1007-1012_(Bach,_Johann_Sebastian) ). Just click on "Suite No. 5 in C Minor". It's the first song. =)

And yes, I realize that this is an epic bump, but I just had to post.
