Played on it last night. You completely fixed the problem of playing in tune, and the ease of playing in the upper register, especially at high D and up, is quite amazing. What I am really having to adjust at this point is all the adaptive embouchure that I am so used to doing for both the low and high end on the soprano to keep things in tune. It is no longer necessary, but is almost done subconsciously/automatically while I am approaching notes at the bottom and top. Fantastic piece. I’m looking forward to playing it live. Without having to put mental energy/effort into keeping the thing in tune or getting decent notes at the very top, I’m excited about putting that energy/effort into creativity and expression.
