b. 32

composition: Op. 63 No. 3, Mazurka in C# minor

..

In GE3 a cautionary  was added here to b in the L.H., which, however, seems unnecessary in this context.

b. 33-48

composition: Op. 63 No. 3, Mazurka in C# minor

..

In [A] (→FE1GE) Chopin wrote the middle section of the Mazurka in a key signature with four flats, although the prevailing key is D major, while from bar 41 even G major. Chopin corrected the key signature in FE2 (→EEW). Such discrepancy between the key signature and the prevailing key happened to Chopin in the Mazurka in G minor, Op. 33 No. 1, which both in the manuscripts and the editions is written down with 4 sharps.

b. 39

composition: Op. 63 No. 3, Mazurka in C# minor

..

In GE1, in the version with 4 flats in the key signature, there is no  lowering G to G. It is most probably an oversight by the engraver of this edition, although it cannot be ruled out that the accidental in FE1 was added only just in the last stage of proofreading. The flat was added in GE2 (→GE3).

b. 44

composition: Op. 63 No. 3, Mazurka in C# minor

..

In FE1 (→GE1), in the version with 4 flats in the key signature, there is no  lowering G to G. It is probably an oversight by the engraver of FE1 or by Chopin himself in [A]. The flat was added in GE2 (→GE3).
