b. 15

d2 in AsI

d2 in A (→GEFE,EE,FESB)

..

Taking into account the three previous similar phrases in this bar and d2 in AsI, one could assume an oversight of a  in A. However, it seems more likely that Chopin consciously changed the pitch of this note:

  • Chopin would often omit accidentals to notes belonging to the current key; however, he would rarely overlook an accidental supposed to define the alteration (only a few times in his entire oeuvre);
  • Chopin did not correct the possible mistake while proofreading FE, despite the fact that he changed slurs in this very bar.

The lack of the  sign ​​​​​​ should be considered Chopin's inaccuracy in this context. The sign was added only in EE.

Crotchets and minims together in FE & EE

Due to small gaps between the notes in GE1, the minims and the following dotted crotchets are written very close to each other; consequently, FE and EE interpreted it as a cue to combine the voices, which, in turn, led to the two notes being played simultaneously. In subsequent bars, a similar situation can be observed.

Both source slurs make musical sense, hence it is difficult to evaluate whether the difference is an inaccuracy, a correction or a revision. According to us, as the difference would have a minimal impact on the performance, it is hard to assume that Chopin would have wanted to correct this very detail. Due to the above, in the main text we keep the notation of A.
