The sources differ in the notation of the accidentals in the 2nd half of the bar; however, none of them includes a manifest error. In relation to the notation adopted in the main text (note number in brackets):

  • in FE (→EE1), there is no  before e2 (1) or a  before a2 (6), in turn, there is a  before c2 (11);
  • in GE1 (→GE2) and EE2 (→EE3), there is no  before e2 (1), but there is a  before c2 (11);
  • in GE3, there is no  before f2 (10).

Above all, the differences result from different conventions of validity of the marks next to the notes that are included or not included by an octave sign.

Fingering in FE (literal reading→GE)

Fingering in FE, contextual interpretation

Fingering in EE

..

When interpreted literally, the fingering in FE raises doubts due to its problematic purpose – the 5th finger on D is most obvious in this context and it is difficult to imagine why Chopin would have wanted to indicate its use right here. According to us, the engraver assigned the digit to a wrong note, hence in the main text we place it under d, where such information is useful.
In EE, Fontana, as well as in a few other places (e.g. in bar 79), copied the change of fingers to d, which, in the light of the authentic articulation, staccato on D, is a totally unjustified complication.

Minim c2 on 2nd beat in sources

Minim c2 on 3rd beat suggested by the editors

..

The version of FE (→GE,EE), although it apparently does not contain a mistake, is certainly erroneous, since it does not correspond to the orchestral part in FEorch – c2, performed by the 1st clarinet, should still sound on the 4th beat of the bar. The harmonic consequences of this discrepancy are practically imperceptible when maintaining the authentic pedalling (this explains the absence of corrections in the pupils' copies), yet the tenth chord, requiring an arpeggio, constitutes an unnecessary pianistic complication. According to us, the cminim was most probably misplaced under the 2nd crotchet instead of under the 3rd one, hence in the main text we suggest changing it accordingly.
