Well today I got a call at about 5pm, asking if I could do a concert at 7.30pm, with a rehearsal at 6pm - at a place about an hour and a half away from my house! I picked up my DJ and rushed out the door, got to the church and was handed a D trumpet: "We're playing some baroque trumpet ensemble stuff and you need to use the D on this". One problem: I've never played a D trumpet before! I'll come to my point / question: on the gig, I was making a lot of VERY stupid errors (getting lost all the time, and general counting mistakes) I split a fair few notes too... well I suppose that was due to my being tired (I had practised all morning), a cold hall, and an unfamilar instrument. I found this immensely frustrating, and I feel like I let myself down, and the people who called me in for the gig. There was nothing wrong with my playing technically I think (sound was nice, breathing was working, and the upper register was there), it's just that I was mis-pitching a lot, and I kept losing concentration. I think the concentration issue may be related to the fact that I am quite tired (sleepy) after a pretty heavy week, and a late night last night. So are there any tips for waking yourself up, and when you feel your mind starting to fall asleep, are there any ways to get back on the ball? Sorry if this seems a little random, it's a vent as much as anything else Cheers, Jack.
