A Meta-etude. Godowsky’s studies on Chopin’s etudes. On Chopin Op 10, number 1, Godowsky puts almost all of Chopin’s notes into the left hand, and then adds a right hand part in counter motion. I wish I had the time to learn even the Chopin version. But these days all my piano practice is jazz standards. Besides the Chopin are hard. The Godowsky-Chopin are ridiculous, but wonderful.
