I've been recording everything and listening back critically to analyze what went well, and what didn't. I will often hear things that sound off, but I don't recall it sounding that way during the performance or rehearsal. Sometimes after going over it I realize it's other players rushing something that makes me sound late or something like that, but it's as often my fault as someone else's. Mostly timing related problems, two notes too close together, a 16th that was more swung than straight, coming out of a fill too fast, etc. So I can obviously be mindful of that section the next time around, but if I don't hear it, what can I do? Is it just a momentary lapse in concentration? Like, if I had been paying more close attention, would I have heard it? I thought I was paying close attention though? This is obviously something I want to fix...but I'm not sure how to go about addressing the root of the problem, or even sure of what the root of the problem actually is. My hyper-awareness (bordering on neuroticism) about this stuff is a relatively recent thing...is it just a matter of time before I hear the improvements I want to make? What I'd like to hear is, "do these exercises every day for 3 months and your problem will go away like magic", but I doubt it's that simple.
