b. 243

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

..

In A there is no  before the 1st crotchet. The patent inadvertence was corrected in GE (→FEEE).
In FE there is no  lowering g to g on the 2nd beat of the bar. It must be a side effect of an inaccurately implemented proofreading of the part of the L.H. encompassing bars 243-244. The mistake was corrected in EE.

b. 243

composition: Op. 22, Polonaise

No mark in FE (→GE,EE)

Accent suggested by the editors

..

Just like in b. 223, in the main text we suggest adding an accent at the beginning of this bar after b. 227 and 247.

b. 243-247

composition: Op. 22, Polonaise

e1-a1 in FE (→GE) & EE2

e1-a1 in EE1

..

Just like in b. 223 and 227, the version of EE1 in b. 243 and 247 is probably Chopin's mistake adopted from a proof copy of FE. The natural raising a1 to a1 was added in both bars in the penultimate stage of proofreading of FE (→GE). The correction was also introduced in EE2.

b. 243

composition: Op. 23, Ballade in G minor

b with  in A (→FEEE,GE)

in GE1a

b without  suggested by the editors

..

The version of GE1a is most probably a mistake by the engraver, although one cannot completely exclude a revision – the cautionary  to b, present in the remaining sources, is not indispensable here and could have been considered erroneous. The engraver or reviser of GE1a was similarly overly zealous in, e.g. b. 232.
In A there is no  raising e1 to e1 in this chord. It is almost certainly a mistake – cf. e1 in b. 240-241 – corrected by FE (→GE,EE). In the main text we omit the cautionary  to b, more justified in the original layout, in which the first 5 quavers in the previous bar – to b – are written down on the bottom stave.

b. 243-244

composition: Op. 2, Variations, complete

..

In the main text we add cautionary flats to E-e in bar 243 and to e-e1 in bar 244, not included in any of the sources of the version for one piano. However, the accidentals are in the bassoon part of AsI, and the first one is also in the double basses and in the cellos.
