The chord with c2 is most probably a result of an oversight of the composer, which is confirmed by the  added – probably by Chopin – in FE3 (→FE4).

In these bars the sources include naturals (cautionary?) before the D crotchets – GE before both, while FE (→EE) only in b. 247. We omit those accidentals in the main text.

Both in the last L.H. chord and in the R.H. arpeggio on the 4th beat of the bar, neither AsI nor Af nor A (→GE1FE,EE) contain accidentals before g/g notes in various octaves. Actually, harmonically speaking, g would be possible; however, in this context, it is much more likely that we are dealing with overlooked naturals:

  • after changing the key signature, Chopin was uncertain which were valid – this is proven by numerous unnecessary flats before d, g, a and even e and b in bars 255-259 in AsI; in A there is still a flat before B at the end of bar 255 and before g2 in bar 256;
  • diminished seventh chords belonged to young Chopin's favourite ones.

The decisive argument for g is provided by the orchestral part – there is a note in the 2nd violins, and the violins could not play g here.

The first edition to add naturals was GE2 (→FESB), 4 accidentals in total raising g1 to g1 in the L.H. and g2, g1 and g to g2, g1 and g in the R.H. The overlooked  to the 2nd demisemiquaver (g3) was added by GE3, in which, however, the accidental to the penultimate demisemiquaver, g, was overlooked.

In the manuscripts there are no accidentals in the second triplet (on the 3rd beat of the bar). In the main text we include both added flats – perhaps by Chopin in GE (→FE,EE) – although it is only the  restoring a1 that is indispensable. Incidentally, also in the previous triplet, an octave higher, the  to g2 present in all sources is also of a cautionary nature.
