Started Sign of the Cross demo. Went into handheld recorder to find the a capella idea for pre-chorus and chorus that I had recorded when song initially came. I knew they were there, but had only done the lick and the verses when playing it on guitar over the last couple of weeks. As a capella ideas are, they're a little hazy so noodled to at least lock in a workable version of pre-chorus and chorus. Should pre-chorus arpeggios be as concise as possible (my default) or should it wander and misdirect? Should song be dynamic and sprawling or eerie and private?
