I said legato toungeing because most of the jazz I play uses that. I agree that jazz cannot be taught in words. It is very different than classical. In classical, you need to play exactly as written with a little bit of expression. I find jazz a bit more complex. There is a lot of room for interpretation. You should learn to listen closely to ALL INSTRUMENTS in various jazz bands. Listen to every different jazz style. Ex, Be-Bob, Swing, Cool, Fusion, Ballad, and blues. Take notice to how each of the instruments articulates. Then try it out for yourself. But remember to keep the articulation with its correct genre of jazz. You don't want to mix them up. Eventually this will become habit, and you will put all of us to shame!!!
