@Bernard is this the Chopin? I am sure thst is much more complex to read than the pieces I read.
I don’t memorize either, for a bunch of reasons, but I do see how that sometimes creates its own challenges. Following the score, knowing where I am not only in the music, but also on the page…
I think of these things as cognitive burdens. For example, I play from my iPad and so I use my left foot to operate a Bluetooth pedal to turn pages. I’ve been using my left foot for page turns for forever…. Like years.
But I still notice that often I have trouble spots at the page turns. And I think it’s just an extra cognitive burden, to have to think about the score, the music, the musicality, and on top of all that, moving my foot just so, all together… and so those become spots where I am a little weaker, a little shakier.
How many pages is the piece you’re working on?
