That guy Gary works with would be............ME. I wouldn't say it is a sign of weakness.......However, since I rarely get time on my horn in a practice room but am required to do a lot of gigs I simply put the air thru the horn and stay focused and it seems to work for me. As of late I have been playing mostly 1st parts and am finding that it takes me about 20 minutes to get where I am comfortable playing. I don't really worry though and just go with the flow...........air flow that is.
