Marching to Battle

My wife's student commissioned this piece. He wanted something that sounded like video game music, so I wrote this piece using the Dorian mode and similar chords to the video games he was playing. I'm still working on an orchestral track to go along with the piano, but since I'm a total newbie at that stuff it's taking me forever. No worries, if you purchase this sheet music you can contact me for a free audio file whenever I finish writing the orchestra part.
