In JC, the  before the chord on the 4th quaver is on the level of d1.

g3 in JC & EF

e3-g3 in PE

..

PE has the e3-gthird as the 2nd quaver of the bar. Admittedly, the version is acceptable, as far as the sound and piano performance are concerned, yet the enote burdens and blurs unnecessarily the melody's line; therefore, a misreading of [A] or a proofing (adding the correct note without deleting the wrong one) seem to be much more probable.

b. 57

The version of PE is an unquestionable improvement introduced by Chopin into [A]

PE, articulation marks interpreted

..

It is unclear what is the origin of the difference between versions of JC and EF, yet they are probably earlier than the version of PE, which we adopt for the main text. In the latter, thanks to a simplified texture, Chopin emphasises the descending phrase in bar 58 (repeated imitatively in bar 59), as well as avoids some complications in voice-leading (parallel sevenths).

No markings in JC & EF

Dots under slur in PE

..

Portato markings (dots under the slur) in bars 58-59 in PE most probably come from [A]. In bar 58 their notation is almost certainly inaccurate: dots over two f1 notes are probably a sign of portato markings over four first quavers, while the slur over the dots in the part of the L.H. should start from the 2nd quaver. Due to the fact that the markings cannot be separated from the version of voice-leading introduced into [A], we include them into the variants described in the note dedicated to this issue.
