Thanks for posting your insights on this. I never had a musical education, so all of this is quite interesting to me.
I know what you mean about what I've pointed out probably being a common musical "sequence", so to speak. I was compelled to post, though, because as I was listening to Beethoven's 8th I could have sworn I heard a familiar melody floating around through there...

... But I know what you mean; the same thing could probably be identified in scores (pardon the pun, heh) of other pieces.
