NTM..the thing that could throw a novice player w/using the Cminor pentover Aminor is that there's no chord tones to resolve the b2 & b5 too...again, if not phrased properly this could sound quite wrong.

J..if someone was playing "wrong" notes just to play "wrong" notes I would probably smack him and then destroy his guitar. -Lol- In the end you really learn there is no such a thing as a wrong note, it's all how you approach and phrase it...check out John Scofield some time. But again, it's all about playing what's appropiate for the song.
