b. 279-280

Fingering in EE

b. 281

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

..

In A (→GEEE1,IE) the  restoring e1 is missing. Chopin's patent oversight was corrected only in FE and EE2.

b. 281-282

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

Slur from c1 to g1 in A, literal reading

Slur from c1 to a1 in GE (→FE,EE,IE)

..

It is difficult to imagine that the literal interpretation of the A slur, which does not include 3 (or 2) outermost quavers belonging to the chromatic scale, could have corresponded to Chopin's intention. Therefore, we consider it one of the many inaccuracies of A in this respect; in the main text we include the interpretation of this slur adopted to GE (→FE,EE,IE).

b. 281

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

Wedge in A (→GEFE,IE)

Fingering digit in EE

..

It is difficult to determine whether the addition of the fingering digit in EE influenced the omission of the wedge, or whether the wedge was mistakenly read as the digit 1, meaning finger 2. It is also possible that the wedge was overlooked and the digit was added independently, along with the other digits in the previous two bars.

b. 282-283

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

Slurs in A

No slurs in GE (→FE,EE,IE)

..

The omission of the slurs/ties between the chords is an oversight by the engraver of GE (→FE,EE,IE). It cannot be ruled out that the engraver did not insert the slurs due to doubts regarding their significance and position with respect to the arpeggio wavy line.
Regardless of the possible dilemmas of the engraver of GE, the meaning of the bottom-most slur/tie concerning c is unclear – if c were to be tied, the arpeggio of the chord in bar 283 would concern only the top 3 notes, contrary to the notation. This resembles the issue discussed in bars 4-6
