Quick background on me; I'm a comback player, was off for about 9yrs and have been playing again for about 3 months. I started taking lessons from a university trumpet professor about 4wks ago. My performances consist of playing with a praise band at church on Saturday nights. I have been struggling with endurance because we do a full rehearsal just prior to the gig. Very little of the music is high, but since they are primarily based on hymns I end up playing nearly non-stop on every song. Which after 3-4 verses and 6-10 songs can get tiring. I was recently asked to play in another praise band on Sunday mornings. They do a Wednesday rehearsal, then on Sunday morning do a quick run-through then two gigs (9:00 service and 10:30 service). I initially told him that I was not ready; I'm still building my chops and three gigs in 16hrs would probably be pushing it. However, I said that I would attend some rehearsals in order to gauge the difficulty of the charts and decided if perhaps I CAN do it. I don't want to push myself too much and put a damper on my progress, but this band sounds REALLY fun from the way the music has been described to me. Thought?
