b. 37-45

composition: Op. 30 No. 1, Mazurka in C minor

,, in FC (→GE)

No markings in FE (→EE)

..

As in bars 5-13 (and with similar doubts), the dynamic markings at the beginning of the subsequent four-bar sections (bars 37, 41 and 45) were entered into FC probably by Chopin.

b. 38-48

composition: Op. 30 No. 1, Mazurka in C minor

6 staccato dots in FC (→GE1)

12 dots in FE (→EE)

18 dots in GE2

24 dots suggested by the editors

..

Upon the return of the main Mazurka theme (bars 38-40 and 46-48) staccato dots for the accompaniment crotchets appear in FE (→EE) much less regularly than in bars 2-4 and 10-12, while in FC (→GE1) to a slightly greater extent than the first time:

  • in FC dots are in bar 46 (both hands) and in bar 48 (R.H.);
  • FE – in bar 38 (both hands) and in bars 39 and 46-48 (R.H.).

Regardless of the reasons for these discrepancies and irregularities, a comparison with the initial section of the piece, in which FE include dots next to 22 out of 24 crotchets, proves that Chopin wanted to indicate the same articulation also here; however, he did it inaccurately. Taking into account the above, in the main text we provide all the discussed crotchets with dots.
In GE2 all dots in bars 38-40 were added, yet in bars 46-48 the incomplete notation of GE1 was left unchanged.
See also bar 45.

composition: Op. 30 No. 1, Mazurka in C minor

In FC (→GE) there is no  raising a1 to a1 on the last quaver in the bar. According to us, the mistake could have already been committed by Chopin in [A]. It is indicated by overlooked naturals also in bar 43 – two oversights of the very naturals to a notes seem highly unlikely for a copyist; however, they are not unusual in Chopin's autographs, who would often mark alterations only the first time a given note appears in a bar.

composition: Op. 30 No. 1, Mazurka in C minor

in FC (→GE)

No sign in FE (→EE)

..

In a different situation, the  mark, added by Chopin in FC, could be considered a long accent on the 3rd beat of the bar. However, in this case, a comparison with analogous bars 7 and 15 reveals that it is the interpretation adopted by GE that is correct – a  hairpin from the 2nd beat to the end of the bar.

b. 43

composition: Op. 30 No. 1, Mazurka in C minor

..

The naturals to the L.H. octave on the 2nd beat of the bar are missing in FC – the visible pencilled naturals were added by the reviser of GE1. It is difficult to say whether it is an oversight by Fontana or by Chopin in [A]. All editions contain the correct text.
