So, after years of playing without thinking about various bad habits, I've been trying to overcome them over the past year or so.... (apparently something huge is still crippling me as far as range and endurance) But I'm still working on that! Even though I'm asking about range here, my practice has been much more concerned about other aspects such as a phrasing, tonguing, and tone.
Let's say that I -have- made significant progress in my body mechanics.... I still need to practice some range exercises each day to get ANY improvement, right? Nothing just "magically" improves through improved body mechanics, except perhaps general ease of playing, correct? Of course, it is said that good practicing also improves body mechanics....but then again, not all good practicing has range exercises.
I'm getting tired of consistently hitting high C#s, but usually missing the Ds. You know of any reasonable range exercises that could likely expand my effective range to a high D, one measly half-step? (Regardless of whether I have overcome any major "bottlenecks" in my playing mechanics!)
Keep in mind my chops are frail and can't handle consistent beatings (only occasionally) so working on this aspect can be tricky. I feel that my teacher gives me practice routines via Colin's lip slurs and such that beat me up a bit too much, even though these supposedly should help with my range. It seems like practicing quietly in the upper register (e.g. high Clarke #1 exercises, adding those reaching beyond high C) is actually more effective for me. One thing is for sure: Clarke #1s warm me up to playing the upper register MUCH more effectively that day. However, I've never really made those part of my daily exercises....
