category imprint: Editorial revisions

b. 238

composition: Op. 22, Polonaise

..

In the main text we omit the unnecessarily repeated  before f1 in the last L.H. chord.

category imprint: Editorial revisions

issues: Cautionary accidentals

b. 241-245

composition: Op. 22, Polonaise

..

Just like in b. 225, FE are lacking in the  lowering c2 to c2. The patent inaccuracy was corrected in GE and EE.

b. 241

composition: Op. 22, Polonaise

g-e1 in FE (→GE)

e-g-e1 in EE

..

Nothing points to a possible authenticity of the version of EE. It is probably a revision by analogy with b. 261 or a mistake, e.g. an unfinished correction of the e-e1 octave – the correct g note was added, yet the erroneous e note was not removed.

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.
