Snork don't even try and preach theory to me son. I have taken years of theory in college, by berkely graduates. As far as my UNDERSTANDING of these things, I was taught using the berkeley pedigogy. So I know my stuff thank you. And as far as learning pentatonic using the "modes" which btw you are using the term incorrectly, then why in the world does BERKELEY PEDIGOGY teach you to play the diatonic scales as well as pentatonic scalesin 5 positions. Just because they contain the same notes doesn't mean you use them the same. And btw when you use the term mode, mode is relevent to not only the scale but the chord structure, when you are saying modes you are actullay referringh to the seven possible starting points of a diatonic scale.
O and one last thing until you have played with actual jazz greats (I.e. Stanley Turrnetine, Fredely Wesley, The Heath Bros. feat Tony Purrone, and the Maceo Parker) I don't think you should be lecturing me on Jazz either.
