So this week, I've rediscovered a major problem in my playing. I don't seem to have the ability to play through an entire etude. By the time I get to the end, I'm blowing, but no sound is coming out. It's just like, all the sudden, I realize I'm about to crash and burn, and a few bars later - game over. I believe it must be happening in my breaths, with a small amount of tension being added each time I play. It's one of those things I feel like I should be able to just fix immediately, but I can't seem to get it together. Overall, this problem has heally had a toll on my confidence level. I'm to the point where I don't feel like there's anything positive about my playing. What makes it even worse is that next week I'm supposed to be recieving a new P3 Monette that I've been waiting on for over a year, and now, I'm just really not all that excited about it due to the lack of motivation I'm experiencing. Does anyone out there have any suggestions about how to overcome this problem? What do you guys do to get excited about playing again when you're in a slump?
