Jiarby, thanks for that, I can totally see a teacher doing that. :) Richtom, thank you very much for the Chicowicz Long Tone Studies mention. I will look into them. I know my air column needs work and that is where most of my focus is right now, because my natural inclination is to get really tense as I go up. So I'm really trying to focus on taking nice relaxed breaths. When you talk about sound concept, how do you work on this? There are a few player who's sounds I absolutely adore and would love to emulate. I really love Haken Hardenberger's sound, Tine Thing Helseth's, Maurice Murphy had an awesome sound. Is it just a matter of listening and trying to emulate?
