b. 42

composition: Op. 44, Polonaise in F♯ minor

FE overlooked the  raising E to E. The mistake was discovered and corrected in EE. In the main text we add cautionary naturals next to the following octave, D-d.

b. 43

composition: Op. 44, Polonaise in F♯ minor

Quaver c2 in GE1 & FE (→EE)

Crotchet c2 in GE2

..

The c2 note having been separated from the 1st chord is an arbitrary revision of GE2. Actually, on the 1st beat of analogous b. 69 the stems are pointing upwards in GE1 and FE (→EE), yet in both places the first chord in those editions is written down using one-part notation. In FE the visible traces of corrections in print suggest that initially the stems on the 1st beat of the discussed bar were also pointing upwards, which was, however, changed – perhaps by Chopin – to a form compliant with the notation of GE.
A similar situation is to be found in b. 276.

No mark in FE (→EE)

In the main text we include the arpeggio present only in GE. It may be one of the elements entered by Chopin into [A] after it had already been copied by Fontana (e.g. pedal markings). An oversight is also likely (both of the copyist and the engraver of FE). A similar situation is to be found in all analog. bars (69, 276 and 302).

b. 43-44

composition: Op. 44, Polonaise in F♯ minor

As was the case with b. 17-18, in FE (→EE) the L.H. part octaves (from the 2nd beat of b. 43 to the end of the 1st beat of b. 44) are written in a simplified manner with the use of con 8va.
