I noticed this with tremolo as well. My understanding, which I must have heard somewhere but who knows, is that when playing slower the brain sends a signal for each stroke of the finger. But as one speeds up, a threshold is crossed where it's not one signal per stroke, but one signal per group of strokes such a-m-i. So now the brain-body executes 3 notes for the same effort as one. Although I know almost zilch about programming, I liken it to sub-routines in an algorithm where a short command can trigger a much more complex routine. A friend who had trained as a ballerina recounted something very similar in learning to execute that very rapid alternation of steps performed on tip-toe. It cannot be performed by consciously alternating from toe tip to toe tip. It has to be fired in bursts.creamburmese wrote:This observation about the brain getting in the way of the hands is very interesting. I was having similar problems with tremolo - I could reach a certain speed (more like a fast arpeggio than tremolo) and then everything locked up and couldn't get it any faster without everything falling apart- speed was only moving up incrementally if at all. Then it was suggested to just go for speed on the first string - starting with just 2 notes (pa) and adding one note at a time (burst of 2,3,4 etc). Suddenly the speed shot up and for the first time I could hear the tremolo sound. Interestingly it feels totally different from an arpeggio - it's like the hand moves into a different mode that is largely independent of your controlling it - it's quite odd - almost as if the hand is on autopilot... and once it's there it's relatively easy to vary the speed and work on the evenness etc
