Well, I'm looking at your Scarlatti and it really is very special. I think you should STOP cutting up photocopies and do something different, and here's why: because when you talked about the piece itself, you used the words seduced, couldn't resist, melodic, lovely (more than once, which it is), and little (more than once-- which it is, short, I mean, but also little in feeling-- delicate, precious). When you talked about your memorization process, on the other hand, you used the words resorted to, cutting up, and doomed. Do you see why this isn't working? Or, if it eventually works, it will still change the way you experience the piece, because you'll have the visual memory of those cut-up bits of paper that used to be your beautiful piece.
Keep us posted! Don't abuse any more of your music, even in photocopies! It will cheapen the piece for you.
