After working on it for almost 4 months, I have decided that this is good enough. It is only for Finele Notepad; so if you dont have that program, you can't view it. If you can view it, then enjoy! I am currently working on the rest of the trailer and hopefully will have it posted here soon again for finale notepad. Sorry, I will try to make a PDF sooner or later for those who are unable to view it. Anyway, here is the Halo 3 Piano Solo, transcribed by spartan182 and young kaos.

UPDATE: SIRBOE below provided a PDF version, which I have also added to the page now.
