Rowuk:
You're a darn sight better than many, and certainly than I am. Sorry if my comment sounded sarcastic.
When I asked how much time you spent on Clarke up two octaves, I was trying to learn how much more work I have to do to get a bit closer to proficiency on the high notes. Some players can go from the pedal tones to the double high C, so the closer I can come to that goal, the better I'll feel about my playing.
I'll keep trying, but my objective in working on the really high notes is to be more proficient overall. If I can do fairly well at the upper end in practice, maybe I can do high E, F, and perhaps G with good tone and endurance when it counts. It seems logical, but I'm just a babe in the woods when it comes to not only the high notes but to overall performance.
I just keep trying.
I enjoy your posts, Rowuk. Keep 'em up.
