Ok separate question now..

If I only ever play basic chords.. like 1-3-5 and 1-3-5-7 chords (Minor and Major).. am I therefore limiting the amount of notes I can play with a solo? I look at the exotic scales that Steve Vai uses and then at the equally exotic chords he plays behind the solo.. and I wonder if the fact that he is playing some weird chord with all these extra notes, like a 9th, 11th or 13th note, means that he is now able to play that extra note in his scales?.. Like say he has added the 11th note of the scale to the chord.. does that mean he can now play all the 4th's and 11th's in his soloing?
