I have started learning this piece, and I'm making quite some progress. I have half of it memorized already, and it is sounding good...
... hands and voices sepereately, that is.

I cannot bring out the RH melody and keep the chords even. The chords are either loud, arpeggiated, or the melody is bashed out, or not heard at all. I am struggling with this, and although I'm sure this is what the etude is teaching, I do not know how to go about learning it.
I also find the fact that there are no slurs on the score to be peculiar. Listening to a recording, one can figure out the logical phrases and musical lines, but nothing was notated. What did Scriabin intend with his whacky time signature and utter lack of phrasing and articulation?
