Do you allow your brain to photograph each measure or are you using mechanical repetition as your method of memorization?
Also, write all over the score.
I personally couldn't do that! I always erase things I don't need anymore, because anything irrelevant in the score may become a distraction for me in action... Fingerings are ok if they are not too messy...I have found a good way to mark sections for practice though, I cut out thin slices from post-it notes. Easily removable
I usually have multiple editions of the score, including laser jet...lol I need notes and I need to write notes to myself. if I don't do it, who will?!
The way you're meant to do it is you're never meant to memorise at the keyboard. You sit down and memorise the score in your head, just like you would memorise your 4000 word english essays, but at the same time you picture the position of your hands in your head as well. I mean, imagine just reciting an essay over and over again, and nothing goes in, that's what happens when you sit at the keyboard. (y)
This would be great, but unfortunately not possible for everyone. I cannot memorize scores alone. I have never been able to memorize text either. Or any sequence of numbers. Something missing from my head...
It still is pretty much route learning, like memorising an essay, but slightly more efficient than say, writing out the essay a billion times.
And who memorizes their essays anyway??
Everyone (out of necessity). picture getting 2 and a half hours to write out 3 essays each 1200 words long. Times have changed, it's all route learning in schools now, instead of building skills.
I've noticed a direct connection between my practice habits and memory lapses in the following way: When I used to practice in sections, but I always started in one particular bar and ended in another particular bar, I was likely to have a lapse (1) somewhere in the middle, or (2) right after the end of that section.Why? In case (1), it's because I wasn't ever really memorizing that measure in the middle, and I wasn't practicing using my explicit memory. I was memorizing how to start the section, and letting my muscle memory carry me through when I practiced. In case (2), it's because I wasn't practicing the transition at all!So I started doing things like this:- Memorize and practice in sections as small as is reasonable- Memorize starting with the last measure in a section- Put extra effort into practicing the transitions in between sections- Practice starting at random measures, even in the middle of sectionsThis works much better for me! In the old way, I would just memorize things automatically as I played a piece over and over, and it gave me a false sense of security. (I've seen this happen a lot especially to young bright students who never had to work to memorize things.) But this way, I know if I have a momentary lapse of focus or lose my flow, I still know exactly where I am.
