I am astonished at the change in positioning. High G and middle E are played in almost the exact same #2 position. I can play high Ab in position #1 with only a slight change in my embouchure. High F can be played in almost perfect #4.
The high D series is somewhat sharp. The high F series and high Bb series are VERY sharp.
I use a 7c mouthpiece. I have thin lips and have always preferred a smaller mouthpiece. I also have always preferred to tune my horn ever so slightly sharp, so that I don't have to come up hard on #1.
I am having to relearn all my upper positions. Is this normal ?
