Ok, so here is another question I have been thinking about. Should I be practicing much on days that I work on long tones? I'm a little unsure, as several people said not to work on long tones or other embrochure excercises if you have a gig that day. I did long tones for several days, and then was practicing for about an hour after each day, but I got soreness where I never had before, to the point of discomfort long after finishing, and also a feeling of my lips not really being able to relax. I've taken several days off, and the discomfort is long gone, but should I have done it differently? Thanks!
