..

Three necessary accidentals are missing in A – flats lowering g1 to g1 in bar 246, c3 to c3 in bar 247 and c1 to c1 in bar 248. These patent inaccuracies were corrected in GE (→FEEE).

Three necessary accidentals are missing in A – flats lowering g1 to g1 in bar 250, c3 to c3 in bar 251 and c4 to c4 in bar 252. The first of them was added in GE1 (→FEEE, →GE2), whereas the third – in EE and GE2. The flat in bar 251 is not featured in any of the sources.

composition: Op. 21, Concerto in F minor, Mvt III

..

In A (→GE1FE) there are no flats lowering g2 to gin bars 254 and 256. This patent inaccuracy was partially corrected in EE1 (→EE2), by adding a  in bar 256. The correct text is only in GE2 and EE3.

composition: Op. 21, Concerto in F minor, Mvt III

..

In A there is no  lowering g1 to gin bar 257 and both necessary flats in bar 260. The signs in bar 260 were added already in GE1 (→FE), whereas all three flats are included in EE and GE2.

In A there is not any  raising e2(3,4) to e2(3,4). It is almost certainly Chopin's mistake – if he were to hear e in this place, he would have used a cautionary flat in this context. The composer also omitted the naturals raising d1(2) to d1(2), which clearly proves that the figures (whose sound, written after so many repetitions, he regarded as obvious) were written hastily and inaccurately. Anyway, the naturals (e2d2 and e4) added in the proofreading of GE1 (→FEEE, →GE2) and uncontested by the composer both in FE and FED clearly prove his intention. In EE, naturals were added also next to d1 and d4, whereas in GE2 – next to e3.
