I came across the theme for flowers in the attic:
Please forward to the main theme at 1:33. I'm trying to figure if it is using relative keys.
It seems it uses a combination of B major and G# minor -- these are relative keys. The main theme uses two chords the G# minor (the I chord of G# minor), and F# (the V chord of B major). Does this sound right? And if this is right, is it typical to borrow different chords of relative keys?
p.s G#minor and F# are both in the key of B major, but the theme seems to center around G#minor.. therefore I'm thinking there's more than one key involved here.
