Well I've gotten a week of absolutely no play rest and my sound feels right again, and tone and range sound like themselves aswell. But I've always had trouble getting a no tongue attack. The tone is in my head, but when i try to attack without tonguing no sound comes out. oldlou, When it comes to marching, I am actually pretty good at it, no added pressure, when you march properly your upper body doesn't sway, or bob at all, so its actually quite easy to play, but this one movement is a huge stretch, and a very scary one, those tubas are HUGE. Also I still am adjusting to the braces even though its been an entire year already. My range is pretty steady, the tone quality is there in the notes, but Im still adjusting to hitting them square on.
