Pete, thank you for your response. Instead of quoting the whole thing I’m simply clipping the part below that I wanted to respond to. but your description and analogy were great and worked for me. I agree. I tried to simplify my thoughts and focus my question. I also used focus on pushing from the bottom of my belly up. But now, I’ve found that doing that causes me “un-useful” tension; so, I’ve come to learn that I can use my whole mid section (stomach and back) almost like a girdle (but a manly one ;- ) ) to control the air stream and pressure. Got’cha. I’m with you on this. Back in college, I had reasonable endurance … in addition to ensembles, I would practice twice a day for an hour and a half. But I found that my lips were tough. or felt thick, because of the muscles I built. In addition to the practice sessions, I would do a slow, hour-long warm-up in the early morning, and I found that this softened my muscles and made them far more responsive later in the day. That said, I was using a completely different approach to playing. Even though I don’t feel that I’m nearly as technical as I was back then, I feel that my sound, flexibility, and dynamics are far superior to where I used to be. I figure that I can rework the technical aspects once I get my embouchure solid again. Thanks, everyone, for your thoughtful responses. I’ve really enjoyed this discussion. Mark, King, and Gmonady, I always appreciate your insight and responses on this and other threads. Certainly, more thoughts are welcome.
