I am a comeback player. I have been taking lessons for the past few years and have really improved. I just can't find motivation anymore. I have tried to find groups to play with, but none need trumpet players in my area. Suggestions? I have been listening to quite a bit of jazz lately. My lessons consist mostly of the basics, Arbans, Clarke, etc. Any utility in trying something new. Are there jazz-specific exercises or playing books to go to?
