b. 230

composition: Op. 23, Ballade in G minor

..

In A Chopin overlooked the  to the bottom note of the 1st L.H. octave (F). The accidental was added by FE (→GE,EE). In the R.H. part A includes a cautionary accidental only to e1. In the main text we also add naturals to c1 and c2; they were also added by GE and, gradually, by EE – to c1 in EE2 (→EE3), only to c2 in EE3.

b. 230

composition: Op. 2, Variations, complete

No fingering in A (→GE1FE,EE)

Fingering in GE2 (→GE3,FESB)

..

The authenticity of the fingering added by GE2 (→GE3,FESB), regardless of it being clearly accurate, seems questionable – see bar 208. The fact that the fingering was added in this very bar could be explained by the urge to remind about this indication at the beginning of a page, which in the case of GE starts from this bar.

b. 230

composition: Op. 2, Variations, complete

4 staccato dots in A

16 wedges in GE (→FE,EE)

8 R.H. wedges in FESB

..

As with bar 224, it seems highly unlikely that the replacement of the four dots (emphasising in A the final melodic idea in this phrase) with wedges (reminding that the variation should be performed staccato) was introduced by GE1 under the influence of Chopin. In this edition this bar opens the page, which could have prompted the engraver (reviser?) to reinterpret the Chopinesque markings in such a way (markings that could be considered incomplete, cf. the adjacent note). The absence of wedges in the L.H. part in FESB is most probably the engraver's mistake.

b. 230-231

composition: (Op. 4), Sonata in C minor, Mvt I

No slurs in A

Slurs in GE (→FE,EE,IE)

..

The sequence of pairs of chords present in these bars is a literal transposition of the sequence from bars 229-230. However, unlike that sequence, the discussed bars are devoid of slurs. According to us, it does not mean that they should be performed differently, as the slurs in bars 229-230 are to be considered a model to be followed also in these bars. To avoid any doubts, in the main text we add respective slurs, compliant with the GE revision (→FE,EE,IE).
In addition, Chopin omitted the slur over the topmost pair of thirds in bar 231. In the main text we also add this slur, as the reason for it having been omitted was almost certainly lack of space under the octave sign – cf. the note on bars 232-236. This slur was already added by GE (→FE,EE,IE).

b. 230

composition: (Op. 4), Sonata in C minor, Mvt IV

No marks in A

Staccato dots in GE (→FE,EE,IE)

..

In GE (→FE,EE,IE) the dots over the three L.H. chords were added probably by analogy with bar 231. We do not include them in the main text, leaving the choice of articulation to the performer. However, taking into account the fact that the use of staccato can be considered the most likely option, we consider the version of the editions to be an acceptable variant.
