Here is the song "Ashes" from the Halo Reach Official Soundtrack. I've finally gotten around to getting this up. This piece takes a little practice to play but overall it's not very hard. Have fun playing and enjoy the sheet music!

UPDATE 5/6/11: Fixed inconsistencies in the sheet music. Big thanks to Pedrotome for the help. Also added the midi for Orchestra Kat's cutscene version.

UPDATE 4/26/11: Replaced old transcription with the new one. The new transcription is based off of the link Chief Mendez kindly provided which was found on Bungie.net. The link can be found at the bottom of this post. I have also made a video of me actually playing the new version and have posted it for all of you to see on YouTube. The link for the video can also be found down below.
