This could be any composer (though it would be nice to see some Chopin, Liszt, Czerny, Moszkowski)
The other thread actually influenced me to post this, because it is always refreshing to learn something simple to memorize which has technical benefits.
For me so far, Chopin etudes op 10 no 1, Ocean Etude, and 25 no 6 (thirds) are all easy to memorize.
I have not dove into Liszt that much so I am not sure about that.
Recommendations?
