Alex, Back in December you wrote these words in a post called Stuffy notes on a specific partial: In December I had just recently started using Book 2 from Buzzing Basics (with Exercises 10 and 11). Prior to that I had done Book 1 (through exercise 9) for the past 3 or 4 years, so I was definitely ready to move on. Here is my current question: you mentioned that your current break is at the C above the staff. Iâ€™m finding the exact same thing that you mention in my own playing. When I buzz the mouthpiece, I get up to the C, but thatâ€™s it. Itâ€™s like Iâ€™m hitting a brick wall! When I play the same exercises on the horn (12 and 14), many times the E and F above the C come out with ease. Iâ€™m not frustrated about this. I realize that the benefit that I am deriving from this daily work has added so much depth of content to my tone that itâ€™s worth every second that I spend on these exercises. I do wonder what Jim would say to me after being stuck at this high C for about 4 months. Would he just say, â€œKeep doing what youâ€™re doingâ€? Or would he assign a supplemental exercise to target this â€œbreakâ€, away from the work with the CD? For reference, I do Book One and Book Two everyday (exercises 1-14) in one session (about an hour and 10 minutes). Prior to this I would do exercises 1-9 everyday and I have eased into Book two over the last 6 months or so. I never miss a day, but every once in a while Iâ€™ll only play through 7 or possibly 9. Any comments for me?
