b. 42

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

No rest in FE (→EEW)

Rest in GE

..

The rest added in GE ensures the formal correctness of the rhythmic notation on the top stave, on which the sources, in addition to the R.H. part, also wrote down the L.H. crotchets on the 2nd and 3rd beats of the bar. Chopin, however, generally avoided writing rests that are not necessary for an unequivocal reading of the text.

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).

b. 48

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

No slur in sources

Slur suggested by the editors

..

In the main text we suggest a slur encompassing the shortened version of the motif in the top voice, which has already appeared thrice – bar 42 and bars 46-47 – always under a slur.

g1 in FE (→GE)

g1 in EEW

..

In EEW there is no  lowering g1 to g1, which changes the sound of all three crotchets at this pitch. It is probably a mistake or a revision introduced in the belief that the 1st crotchet in the bottom voice is a repetition of the last note in the preceding bar, as was the case with the two previous bars. See also the next note below.
