According to an anonymous user, it is possible that no. 20 in this set of pieces by Scarlatti has been mistakenly categorized under Scriabin, presumably by mistake.

I don't know the piece, so I can't say for sure it's by Scarlatti (and no composer name is given on the score). But it certainly looks very much like Scarlatti; and I know Scriabin's music intimately, and I can say for sure it is *not* by him. M.J.E. 04:03, 17 October 2008 (EDT)
