Hey thanks CSchlegel, great that you covered it. I just feel octaves been mostly overlooked during the learning process. Ok heres another that might interest some. I'm sure most players know that if you were to play all the notes in its natural position shows you all 7 modes laid-out on the fret board but I think most arent aware that if you play all the unnatural notes (# b) in there respective positions gives you the 5 major/minor pentatonic patterns. Its easier to see with the graphic diagram that I've attached.
Black dots for the regular modes and yellow for pentatonic.
