I redid the Halo 2 Theme and fixed its mistakes. It is now played with violins and a cello and is played in the right key. It is also set as string ensemble for better quality sound. Again you can change it by selecting "instrument list" under "window" at the top of the page. Once again it is for Finale Notepad 2009.
