Wanted to put up a discussion on doubling the octaves periodically for this etude. Mosty notibly in Georges Cziffra interpretation. For example at the start of each bar on the final chorus he would double the bass note: The first note on the left hand which is C with the lowest C on the piano, making the piece more difficult and also giving it an explosion effect.
For anyone that can play this piece or is just generally interested in this topic, what do you think about this? If you can, leave your recordings of trying this out, I will post mine too.
