I play this Scriabin etude in C# Minor.
Most typically do For this particular etude I would actually go against what I'd normally say and tell you it's not a bad idea.1) Scriabin's music in the first place seems somewhat impromptu and very varied - tactful additions seem to fit well.2) The beat is a gliss already and he often created this type of sound.3) This seems to be a tactful addition.4) I too have the Horowitz recording and it sounds powerful - but I wouldn't do it just because he did.I would not do this in the first bar though - too much too soon.
