I am somewhat curious to know which piano etudes are among the ones you find the most rewarding.
Say given 3 categories : beginner - intermediate - advanced.
Bach of course.
But then there are numerous later on : clementi, cramer, czerny,moscheles, brahms, chopn, moskowski, scriabin, ...
or if you like : for finger independance: x, for velocity: y, and so on.
But I find Brahms 50 exercises hard to place.
I know, 1 etude played to perfection, is better than a 1000 touched in the air let's say.
But still any ideas are welcome.
