The lower notes of the chords on the 2nd and 3rd quavers in bars 2, 6, 10 and 14 were removed by Chopin in a proofreading of FE (→GE,EE). It was probably related to the change of the dynamic concept of these bars. Similarly in bars 50 and 54. category imprint: Differences between sources; Corrections & alterations issues: Authentic corrections of FE |

A (→FE→GE,EE) has d3 as the 3rd note of the 3rd triplet, changed by Chopin to e3 in FED. Taking into account the analogous corrections made in A in bars 12 and 52, we consider this change as definitive.

We add a cautionary before d1; it was already performed in GE and EE4. We remove the unjustified before c1 in the 2nd chord; the change was already introduced in GE and EE4. category imprint: Differences between sources issues: GE revisions , Cautionary accidentals , Last key signature sign |

In A the head of the note embraces the area of two notes, d3 and e3, which stems from the simplified probably hasty correction. In spite of this, in FE (→GE1,EE2→EE3) it was correctly interpreted as e3. However, the reviser of GE2 (→GE3→GE4→GE5) changed it to d3, which was accepted as legitimate also in EE4. category imprint: Graphic ambiguousness; Differences between sources; Corrections & alterations issues: EE revisions , Corrections in A , GE revisions |

Lack of e1 in the editions is, according to us, a result of a misreading of A, yet Chopin could have accepted this version at the stage of proofreading FE. Therefore, in the main text we suggest a variant solution.
In A there are visible traces of corrections, perhaps from the following version:
