I still remember when I was a little kid, practicing piano. (Started young, stopped when I began college.) I didn’t really know what “practice” was, and I wasn’t told. Like most people, I thought it meant doing something over and over and over and over and over and over … and it would just somehow “get better” by magic. Sometimes, it did. Sometimes it didn’t, and when it didn’t, it was obdurate failure. Like with my trills. Just doing it over and over a million times didn’t work. I still have horrible trills. I got good by practicing that way, but I didn’t get great, nor was I going to with that approach. Other obstacles prevented further forward movement as well, mostly the fact that while piano was like paint-by-numbers, mathematics and science were innovative, welcoming of novel approaches, and incredibly creative and joyful … something you couldn’t get most musicians to understand if you hit them on the head with it.
Now, as an adult learner, I seem to have stumbled on a very simple lesson. Practicing is problem-solving. The single most useful thing I’ve done is to make a spreadsheet of a given piece with three columns: Measure Number, Problem, Solution. Then, I just go through a piece bit by bit and crush each problem out.
I also have learned of the wonders of mental practice, something that I don’t recall have been introduced to as a kid, but that may have been beyond me until adulthood. It doesn’t strike me as the sort of thing that would really gel for a little kid easily, not without a lot of mentoring. Go through the piece in your head, only without the instrument. If the piece is 6 minutes and 2 seconds long, your mental practice session should take 6 minutes and 2 seconds. Everything happens except the muscle movement. It’s easy to do before you drop off to sleep, and relaxing, and it makes an enormous amount of difference.
I wish I’d known these two things earlier. I might have a trill today. I hope to have a good one on the viola, at least.
