The cautionary flat before dwas added in GE (→FEEE). In a similar context, Chopin would frequently write signs specifying the pitch of a note, compliant with the key, after previously raising it an octave lower. Therefore, it cannot be excluded that the addition comes from the composer.

The flat before the d minim in the L.H. was added by us.

The later started slur in the majority of the editions is a result of inaccuracy of the engraver of GE1 (→FEEE).

Subsequent shortenings of the  sign in GE and FE (→EE) are certainly accidental. In the main text we reproduce the notation of A.

Beginning of slur in A, contextual interpretation

Beginning of slur in GE (→FEEE

The beginning of the slur of A is undoubtedly inaccurate; however, it is unclear from which note it was supposed to start, according to Chopin – from the 2nd fsemiquaver, from the sustained esemiquaver or maybe even from the ecrotchet, as it was interpreted in GE (→FEEE). We adopt the second of the possibilities as the text of A due to a slightly similar situation in the previous bar. Being uncertain how A is to be interpreted, in the main text we give the unambiguous notation of the editions (equivalent to the one we adopted to A).

F in A (→GEFEEE)

G suggested by the editors

At the beginning of the bar, we give in the main text, present as the bass note in the orchestral part, Morch. It would be unthinkable that the seventh placed in the bass would remain unresolved, moving on to in the next bar, present in the double bass part. A possible reason for the erroneous presence of the note in A is imagining only the solo piano part when writing A, in haste. In this case, the actual bass line (including pedalling) forms an A-G-F sequence:
.
The version with F may be considered an acceptable variant only when performing the piece without accompaniment.
