pianoloverus since I've practiced this piece a lot with the score I assume that makes it easier to find my place back in the score since I'm so familiar with the score
I know that this applies to me. With a score Iāve played a lot, I have a very spatial memory of it. For example, I know which sections occur on what spots on the page, such that, if Iām not looking at the score, say Iām not even at the piano, I can call to mind where a specific pattern occurs. In other words, I could say at the top line on the left side of the page, bottom line on the far right, second line in the middle of the line etc.
I also do this with written text, something Iām studying etc. If itās a physical book, I can also tell you whether a specific topics appears on the left page or right page.
This is something Iāve always noticed about myself, and Iām sure it contributes to the ease I feel of playing from a score.
I donāt know if this is a skill that could be developed, but maybe itās one way to get more comfortable reading. Maybe @TC3 you could practice this ā for example, listen audio (so youāre not using your hands), follow the score with the music, and periodically look down (to the specific note of course) and then back up.
If that feels easy enough, then do it while you yourself are playing. Pick easier music and make it a point to look down and up again, maybe even more than you need to, with the intention of training yourself to find the right spot on the page each time you look back up again.
This is like āscore geographyā as opposed to keyboard geography.
