Hi, I got a couple questions: 1)It seems I focus on my "head" area too much when playing trumpet. I noticed when I really try to focus on pushing air from lower in my body (my stomach) my air use improves a lot; I learned this when I was working on one of Clarke's Setting Up drills exercise 14 involving tonguing/slurring fast eighth notes. I was only managing to make it 3/4 of the way through at quarter note = 90 (I can do it faster, but some days I have to slow things down to keep my tonguing and fingering in control) I was only able to make it 3/4 of the way through. Then, when focusing from my stomach and trying to relax my face and neck, I made it through the whole thing... with a little breath to spare. Question is: is there a good way to help me be more consistant with that type of breathing? Yoga-type stuff? I'm not sure. 2)When my lips start getting tired, you would expect me to start going sharp. However, I start going FLAT. This was an issue a few years ago. Then, I worked really hard to not worry about going sharp and it seemed to help. Then, in the past two weeks, I had a very hard week or playing (lots of demands, couldn't take a lot of breaks) and now I'm starting to go very flat again. My trumpet buddies have their slide about 3/4 of an inch out perhaps, while I am at like 1/4 an inch out. Previously I had my slide out about 1/2 inch. Additionally, the more tired I get in a rehearsal or practice session, the flatter I get (well, not always, but frequently). Is that something to worry about? You think I should flat out ignore sharpness, and just always pull my slide out when it starts to happen? My theory? I think it's because I recognize I am going sharp, especially in the upper register where my lips cannot auto-adjust the intonation so easily due to the close partials.... thus, my lips work very hard to keep the pitch down. Then, that eventually causes me to "permanently" be lipping down, even when I try not to lip down. It just comes like that. THanks for any help you can provide.
