Focusing issues again because I wanted visual on my hands.
Pro Tip: to really minimize the chance for error, you just have to choreograph and rehearse every "shift" and every right hand pattern. What does this mean? I've been navigating classical guitar pieces for years just more or less spontaneously hitting more clean notes than rough ones, but what do the pros do? I theorize that they really conciously execute every left hand shift with thoroughly rehearsed movements - and unsual right hand patterns are identified and really practiced ad nauseam. We'll come back to all this another time.
