I wasn't going to comment on this one because it's not my favorite etude. And then after 1 minute of listening I got pulled to like another dimension!!! Like I was half asleep and still listening.
I think you are on to something, I can't put my finger on it, but you are doing something special with this piece. You probably know what it is, because you're doing it, but I'm not sure... I'll listen again...
30 seconds later. I got it. This is a lyrical piece. It has nice chord progressions!
Most of us would do alot of "give and take" with the rhythm. What's this called? rubatto?
You don't do it. Maybe just a tad in one spot.
What you do instead is play with the volume - dynamic range.
So after a while, by that steady beat, I sort of get "sucked" in or "suckered" in to an agitato state of mind.
Mr. - did I make any sense?
