Hi,I am learning Chopin's Etude op 10 no 3 since September Currently I have all the piece read, but in a slow tempo (80 bpm per sixteenth) and with some stumbles with certain intervals (the sixth ones) and some parts if I lose my focus and train of though. Also not everything is in memory although I can do it if I focus more in that aspect. However, there is something that I think I am missing in order to advance in this Etude: the reason Chopin created this Etude: what can I learn and improve as a pianist if I am studying it?, what is the goal for learning this etude?, how can I reach it?
