Memorsing day two

Today I sat down and played Dr Gradus cold, without the printed music. I had to finesse some bits in the middle section. In a few places in the final part, I had some new stumbles, where I have never had trouble. This is the 1st time that I have worked specifically on memorizing a piece. Usually I just play a piece through so many times that I can eventually play it through without the printed music! I realize that if I want to have a piece memorized, I need to practice without the music every day. It seems important to keep trying to play pieces without the music before playing with the music!! After I have played through the piece from memory, I look at the score and analyze the section to find guideposts. It is encouraging that I remember so much and surprising that I have new places where I stumble.
