I can always play from sheet music better than I play by memory for the most part.
I'm learning "kiss the rain" by yiruma which isn't hard at all - very simple but yet it is still pretty hard to memorize. I've gotten to a point where I could literally read 70% pretty well (with little flubs and pause here and there) of the piece but I still memorized the first page (of like 5)
Here is the sheet music: https://musescore.com/messo46/kiss-the-rain-yiruma
I want to make a little one page reference notes for the whole song but I don't know how to make an effective note.
There is a lot of repetition in the piece but just the minute details like the middle voicing and the harmony, and the pattern variations.
How do I convey that those parts in a minimalist way?
