wiz even mo random reference to a legend 
"I had read somewhere (before hearing any of Chopin’s etudes) that the second etude, Op.10, was so extremely difficult that many professional pianists playing the set today actually miss it out. You might have guessed by now that after hearing that I had to hear this piece.
I have the complete set of Etudes recorded by Tamas Vasary, who I believe to be an excellent Chopin player (his renditions of the Ballades are marvellous as well). Upon listening to Etude Op.10 No.2 I was almost in disbelief…no, not at the huge difficulty, but rather at the comment I’d read about this difficulty. The piece sounded so simple - a ‘twiddly’ right hand against simple chords in the left, not even played stupidly fast. I was sure I had found the wrong etude. Then I got the music…
What I had thought was a simple tune in the right hand (and would have been, had it been all there was) turned out to in fact be that tune played over chords in the right hand i.e. the right hand was twiddling and accompanying itself (to a degree) at the same time. What this meant was that in order to play the chords the tune (rising up a long chromatic scale), which was quite quick, had to be played by only the fourth and fifth, and occaissionally third, fingers of the right hand. Ouch.
I watched Freddy Kempf play the etude on TV, and he commented that ‘after 30 seconds you can feel a burning pain shooting through your forearm; by the end of the piece you are gasping for breath and with a near-crippled right arm’. "
