I was working a certain piece and it was killing me to get it up to speed. I took a few minutes and went to a new piece. I had some fun and tried to play this other piece as fast as I could. Now, my brain was now having to work at a faster rate of speed and when I went back to my previous piece my brain was still working at a faster speed and therefore was able to think quicker and react quicker to the piece. In turn, my piece improved tons by playing something else.what do you think? or is this something that everyone knows already?boliver
