Let the current flow through the whole instrument. Whatever you want to play, even written music of any sort, begin only when you have done what I have recommended. You will then experience everything on your own. Before you play, you may let your thoughts run free, you may train the muscles of your fingers, of your larynx, etc. But now you know what you think and train for, and even the thinking and training will be completely new, completely different from before.
Nothing is as it used to be.
As long as you retain this consciousness, everything you do will be right and good.
