If you're talking about the cutscene that starts off with, "I have so far to go..." That's the song "Shattered Skies", a shortened version of "Blue Skies", the credit theme.
If you're talking about the cutscene that starts off with, "I was just a child when the stars fell from the skies..." That's the song "Prelude".
Actually if you're reffering to the Guitar piece in the first cutscene, the "I was just a child when the stars fell...." one, it's called "La Catedral"
