On an unrelated sidenote, which Sonata is a good starter (presumably it should be one of the first 5)? I think #8 is beautiful, and #10, but these 2 are probably rather difficult.
Can someone explain what's wrong with the Belaieff?
I think #8 has some of the most delicious chords penned by Scriabin.
