I was suspicious of a common misprint of a missing note in both my copies of this etude, so I checked to see if imslp had one. They do: link

Indeed, the note is there in this older version, but it’s 1 versus 2. Maybe Karl Klindworth inserted it and the newer copies are using the original?

Also, notice the way it’s notated, separating the voices. What’s also interesting is Klindworth’s pedal marks, which contradict the ones in my other copies at the end. In general I find pedal marks should be disregarded and one should use his own ear to get the style/feel he wants. Personally with this piece I like using minimal pedal for color only so that the left hand is distinctly staccato.

Also I think I want to relearn the right hand so I’m not playing the eigth-notes in the melody as sixteenths. You can cheat if you pedal as suggested but I really like the staccato bass notes.
