Oh, I see! 
Then, could you explain how you approached memorizing? I have many problems with that, and would like to know what the method is in an experienced student.
Thanks Marik!
I don´t make this a PM because much people would be interested in that subject i guess.
When you memorize you engage different kinds of memories. To be honest, I am not good at memorizing either. For me it is a hard menthal work. The hardest thing, especially with beautiful pieces, is not to get carried away and start performing, but have a discipline and actually work on it, otherwise it can take many days untill I know them well.
Usually, my drill is: first day I sight-read the piece through in tempo without stops "fluffing though"-- just to get general idea. Then play it once again, but slower, with stops at difficult places, trying to analize them, realize fingering, etc. Then I play it once again slowly from the beginning to the end and put away.
Second day I play it through in tempo, then start memorizing right away. I take a small section and glance at that, trying to catch all details, then play it a few times, without looking at the score. Of course, I have to look at the score a few times untill I feel comfortable. Then I go to the next section. After that I connect those two, and play untill, once again, I feel comfortable. Then goes third section, and so on. Before I know first page, I never go to the next one.
Next day, of course, I don't remember anything, so I play ones what I just have learnt with score and then start the same drill from where I stopped yerstaday. After I got to the last measure, I put away untill next day. Then I start again from the beginning exactly the same way, but for now it goes much faster. Usually, it takes me three times of going through the piece, untill I know it well--about five-six days for long and complicated works. The longest I remember was Rachmaninov 3rd Concerto, when I spent 2 weeks for memorizing second and third movements, working 9 hours a day.
For Samuil Feinberg Sonata No.6 I spent about 10 days for memorizing--very difficult music.
Yeah, I had a friend, who memorized Pictures from Exibition in 5 hours!
One of my professors memorized Beethoven Op. 101 in 3 hours. Once, right before his recital, he came to a green room to warm up, and found on the piano stand a score of Villa Lobos Polichinelle (spelling?). He sight-read it twice and then.... played as an encore--of course, it was perfect
