How to memorize technically easy pieces?

[onwan]

Hi guys, 

I've just started learning the first movement of Schubert's Sonata in G major, no. 18, D894. I can go through the whole movement just by sight-reading. There are only few technically difficult spots. So the hardest part in the learning process is memory. How do you learn such long pieces when there is a little need of practicing the technical part? I know that the interpretation is completly different topic, but I can't focus 100 % on the interpretation if I'm not sure about the right notes.

Do you have any tips on how to memorize technically easy pieces effectively and quickly so you can focus on the interpretation?

Good question.  I've faced the same issue.
You could look up the YT vids on memorization, btw.

To memorize well you to need engage the the mind, you need to study the piece away from the piano.  Muscle memory is not enough.  You need to analyze it - it's form, it's harmonic sequences, it's motivic sequences.  Study the score and take notes.  Then sit down at the piano with the score next to you but not visible and play from memory. When your memory fails, you need to ask yourself, what happens next, look at the score, and understand mentally/verbally what happens next, what is the relationship between the music before the memory lapse and after?  And then go back to the beginning or a previous section and try again.

It's painstaking work, but very rewarding.
