Hey I’m a piano guy and I was wondering if there’s a book that has all of music that was in all the Halo games? I would like to learn how to play the songs like Halo CE’s Theme, “Another Rain” from Halo 3 ODST, and Halo 4’s theme. If there isn’t a book that has the songs can you suggest any other way for me to learn the songs please?
I don’t know of an official book with all of the sheet music within it, but I know Rampancy.net has a lot of fan-transcribed music from all of Bungie’s games including Halo, Myth, and Marathon. As for official stuff, try this and this.
