Hi all.
I'm pretty new to euphonium and I've come across an interesting problem. While working on improving range, I've come to realize that I am having considerable difficulty getting a high (3rd ledger line BC) G. Not because of lip fatigue, but because the note is so finicky. I typically overshoot but I can't gradually slide into the G. No matter how slow I take it, I somehow just skip over the partial completely. I've tried pressing all three valves, working up to the partial, and then working chromatically to the G. G-flat and A are not a problem, at least not more of a problem than I'd expect at my skill level. It's just this particular note is so freakishly picky.
Now I have gotten the G and I've even been able to hold it, but I'll lose it if I so much as move an eyebrow. The only embrochure that's ever worked is so different from my "normal" one (suddenly have to switch to upper lip dominance when I don't need to for any other notes, including higher ones) that this CAN'T be right.
Is getting this note down a typical newbie problem? I know some notes are a bear to get right on certain instruments. But nothing has given me this much trouble before. I have been trying to sound this note for weeks and it's not an exaggeration to say I've seen absolutely no improvement on this. I don't know what to do outside of talking to a teacher, or at least a more experianced player, in person. I guess I'm just wondering if I'm not the only one who's struggled with this.
