I designed this course to teach aspiring musicians how to play by ear. I've spent a lot of time and effort making this course. More information about this course is available in my profile page. I hope you'll enjoy it as much as you enjoy my YouTube videos!
This is video tutorial on how to play the piano part of the Halo 3 E3 2006 announcement trailer. Post your versions up when you learn how to play it!
EDIT: The musical scale is actually E Dorian, sorry about that.
