My how the world has changed. When I learned a piece when I was young, usually I never had heard any performance. So I would play the right hand slowly until I wasn't making mistakes. then I would play the left hand slowly until I wasn't making any mistakes. Then I would put the hands together, extremely slowly, to make no mistakes.
After some weeks of this, I could speed up a little and pay attention to the expression markings the composer, editor, or publisher had put on the printed page. Editions vary, I only had one.
So, necessarily, every performance of a piece I made, was inherently my own. The teacher gave me some guidance, but not a lot.
After I had done that, after the FM radio became affordable, sometimes I heard on the radio performances by great artists of pieces I could play.
Sometimes I liked the artist's performance better in some ways. So I would change. Sometimes I liked my way a whole lot better. So I wouldn't change.
The difference between painting by number and painting in plein air is the second way comes out your own way more often.
Yes, after I have the mechanics down, I can appreciate other's performance or goals, or historical accuracy, or emotional state, or whatever. But my own way is often quite pleasing, like home made bread.
This sort of emotional innocence about music will be totally lost on the internet generation. All the libraries of the world at the touch of a few keys. Everybody has heard everything. How will anybody create any new performance without a huge emotional rejection that everybody before was wrong?
I'm not a rebel, I'm just a do it yourselfer- like my fathers before me. My grandfather built a house out of scrap lumber to excape the discipline of the company coal mining town. (it still stands occupied). I make up my own musical performances, and electronic devices.
