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

b. 283-287

Slur in EE and FE

GC (→GE)

..

In GC, the slur ends in bar 283 at the end of the page. The fact that it is not continued on the next page is probably an oversight. We adopt the consistent version of EE and FE.

No indications in FE, #E & EE

Fingering indications written into FED

..

The signs written in FED under the 4th quaver in bar 283 and under the 2nd and 6th quavers in bar 284 most probably indicate a more convenient performance of the passage consisting in taking these notes over by the L.H. It is not entirely clear what it exactly is – according to us, they are additional quaver flags (cf. the Nocturne in C minor, Op. 27 No. 1, bar 27). We include these meaningful practical hints in the main text.

FEG (→GE)

..

In each of three editions Chopin marked the ending of crescendo differently. The version of EE – if it reproduces Chopin's notation correctly – may be considered as intermediary between the shorter crescendo in FE and longer in GE. In the main text we give the version of FEG (→GE) written with the composer's hand.
