When I searched I found there is some interest in memorizing music here. There seemed to be a lot of ideas not put to the test. Has anyone figured out more? I'm specifically interested in sheet music for piano.
I have a big goal of learning and memorizing Chopin's Ballade No. 1:
Here are examples of the sheet music:
And a more complex one
My first idea was turning each of the 88 piano keys into numbers. After learning this you would have them to reflex level, so you instantly know where all the numbers are located. Then you turn all the notes into numbers and memorize them in a loci in sequence, for each separate hands.
This would be quite many numbers. A rough estimation gives me 400-600 digits for both hands for one page. So for this piece around 5000 digits. This approach would not take into account what value the notes have. You would also need a way of separating notes that should be played simultaneously or not.
