b. 335

composition: Op. 2, Variations, complete

..

As in the entire Variations, while writing A Chopin treated accidentals almost like key signature accidentals – he considered them to be valid in all octaves on a given stave and in a given clef. Therefore, in the R.H. part the last entered accidental is a  to d1, while in the L.H. part it is the sharps to Df and all starting from d2 that are missing. All necessary accidentals – assuming that they are also valid for notes at the same pitch under the octave sign – were added already in GE (→FE,EE, in the latter the notes under the octave sign were also provided with accidentals).

b. 335-336

composition: Op. 2, Variations, complete

..

The slurs of AsI are written offhandedly; they signal an intent rather than represent actual marks. This intent were most probably slurs encompassing the entire passage, including the 1st quaver in bar 336.
In A both slurs – both in the R.H. and the L.H. – indicate that the slurs from bar 335 (at the end of a line) should be continued, which is, however, not confirmed by bar 336, which does not contain their endings. In this case, there are no doubts that the slurs are supposed to reach the end of the passage, and this is how it was interpreted in GE (→FE,EE). In FESB the L.H. slur erroneously reaches only the end of bar 335.

We believe there is little chance that Chopin consciously left out sotto voce at any stage of preparing FE.

b. 336-343

composition: Op. 39, Scherzo in C♯ minor

..

Slur endings in bars 339 and 343 are innacurately notated in GC as the slurs extend over to the rests on the second beat of the bar.
