BrAVO ! I think you really covered all the aspects of complete memorization. I, personally, only could think of five. But you've developed them even more. You said tecnique has nothing to do with memorization. But memorization has a lot to do with a clean finger technique. I discovered years ago, that if a passage of fast finger work doesn't come clean or perfect every time, it means my mind hasn't completely learned the passage. For example, the scherzo in the chopin bflat minor sonata. I was never really pleased with the result so I sat down without the music and began to solfeggiare the right hand. g-aflat-anatural-c-bflat, etc. etc. I couldn't get through it. I had to look at the music to be sure. In short, I had only memorized the physical feel of the hand as it tore through the scherzo. Sure enough, when I was able to recite the notes, seeing my fingers touching each individual note in my mind, then playing VERY slowly ONLY the r.h. I had no problems after that. It was really a cinch.
