b. 21

composition: Op. 30 No. 4, Mazurka in C# minor

Slur from semiquaver in FC (→GE)

Slur from crotchet in FE (→EE)

..

It is difficult to say what the slur of [A], perhaps inaccurately written, could have looked like. In the main text we give the version of the principal source, FC.

b. 21-25

composition: Op. 30 No. 4, Mazurka in C# minor

4 wedges in FC

4 staccato dots in FE (→EE) & GE2

3 dots in GE1

..

The F crotchets at the beginning of bars 21, 23, 25 and 27 are provided with wedges in FC and with dots in FE (→EE). As the second time (bars 117-123) both sources are provided with dots, to the main text we adopt this kind of markings. In GE the wedges of FC were reproduced as dots; moreover, in GE1 the mark in bar 21 was overlooked, supplemented in GE2.

Dots & slurs in FC

No markings in FE (→EE)

Slurs in GE

In bars 22 and 24 the L.H. sets of markings – consisting of a staccato dot and a slur – could have been added by Chopin to [A] after FE had already been engraved. It is less likely that they could have been added by Chopin to FC, since they are not characteristic of Chopin's additions.
The absence of the dots in GE most probably resulted from an oversight (or perhaps they were ignored? – both are very small) by the engraver.
Similar situations are to be found in bar 28 and in bars 118, 120 and 122.

composition: Op. 30 No. 4, Mazurka in C# minor

..

In FC one can see cautionary naturals to a1 in bars 23, 25 and 27, added in pencil. They come from the reviser of GE, and this is the only edition in which they are present. We include them in the main text.

b. 23-25

composition: Op. 30 No. 4, Mazurka in C# minor

Arpeggio sign in b. 23 in FC (→GE1)

Arpeggio sign in b. 25 in FE (→EE)

2 arpeggio signs in GE2

..

The missing arpeggio marks in bars 23 and 25 must have resulted from oversights by the engraver of FE and the copyist, respectively. In the main text we give marks in both bars, which almost certainly corresponds to the notation of [A]. A similar addition was introduced in GE2.
