To solidify memory, I will learn to play in reverse (and from memory) sections that trouble me the most! This is really just an extension of the other tools I have explained here already:
Let’s take a passage from Scriabin Sonata No. 5 that trouble me a lot:
I will learn to play from memory only left hand, start with Bar 7 and then Bar 8, pause, then Bar 5 and Bar 6, pause, then Bar 3 and Bar 4 and so on. Do the same for right hand, and also hands together.
If you want more security with memory, learn to play following from memory: Bar 8, pause, Bar 7, pause, Bar 6, and so on. The smaller the unit, the harder it becomes and the better your memory will be for this passage.
I find the left hand for Bar 2 and Bar 6 specifically hard to memorize. I will learn to play from memory Bar 1 and beginning of Bar 2; pause; then proceed to Bar 5 and Bar 6; pause ; then back to Bar 1 and Bar 2; and so on.
