Re: is this little wind theme original, or not?
Well, this isn\'t a typical theme. It\'s more accompaniment figure. Of course you hear arpeggios in most pieces, so there\'s really nobody who can claim that this and that arpeggio is his \"property\".
You are fine, just use it if you want to.
Anyway, I think I heard something similar in the Starwars Intro. But like I said, nobody can claim ownership on arpeggios. J. Williams probably heard his arpeggios in someone work.
