All sources feature a  (cautionary?) before e1. In the main text we omit that unjustified accidental.

Due to the division of the bar between the lines adopted in our transcription, we repeat the  before b in the 2nd half of the bar, which is not necessary in an undivided bar and which, therefore, is absent in the sources. That procedure does not influence the interpretation of the text, and we reproduce the literal notation of the sources in the graphical transcription.

Dotted minim in sources

Minim suggested by the editors

Holding the g note to the very end of the bar, as it was given in A and in all the remaining sources, is inconvenient from the pianistic point of view and practically imperceptible against the trill performed with pedal in the bass. Therefore, it is almost certainly a mistake of Chopin, who did not realize that in this bar – unlike in all analogous ones – the first note of the bar is not a part of the chord on the 3rd beat.

Slur in A

No slur in FC (→GE) & FE (→EE)

The small slur combining the trilled crotchet with the quaver that opens the next bar was overlooked both in FC (→GE) and FE (→EE).

Chopin started crossing out and correcting the R.H. part; afterwards, he decided to rewrite the entire bar, on the staves above. The changes probably concerned two elements:

  • rhythm in the 1st half of the bar, which initially did not include a semiquaver rest – ;
  • notation of the grace notes, which were small semiquavers in the crossed-out version.
