I've heard from so many articles, people, and certain books that advocate the use of mental practise over physical practise. But from my experience, I find it extremely hard, and have only gained limited improvement in it with my piano technique. I have a hard time imagining the physical subtleties and changes within my fingers and the movements in between keys, all mentally, it gives me a headache. Is there something wrong with me, or is mental practise simply not for everyone?
I spent the greater part of my life without instruction, so I certainly didn't know about things like "Meticulous Attention..." or other things. Apparently I did some kinds of "mental practice" without knowing about it as a theory or idea. I would look at a score and sight sing the melody, and find patterns. My mind would keep playing with those melody patterns while I went about my business, taking a walk, preparing supper, grocery shopping or whatever. Much later I discovered another important component - going over physical elements. This was on violin and I came up with the idea of remembering things like 'bow distribution" (which section of the bow to use for which section of music) and shifting positions. Still later I learned from my teacher to do things like being consciously aware of chords, chord patterns, chromatic movement and such - though this tended to be more in conjunction with reading skills.I actually didn't know there was such a thing as playing music without also doing these other things. That, too, is a good thing to be able to do. Looking at notes on the page and having your hand scoot to the right piano keys is a handy skill.Well, if you're studying anything, don't you tend to think about it in between your reading? I'm not good at sports, but I imagine that serious athletes and sports people would also go through things mentally, and some who are not formally trained wherever might still do so.
