Actually, Sarcophagi is played by two guitars, a ryhtm guitar and a solo,
while the latter plays the high pitched notes. I tabbed Sarcophagi for one
guitar, so the high pitched notes of the solo guitar are built within the
chords. It's easy to play and sing along this way. Probably not the most
accurate, but the most enjoyable version.
