b. 75-76

composition: Op. 30, Mazurka in D♭ major

2 slurs in FC (→GE)

Continuous slur in FE (→EE)

..

It is difficult to say how the difference in slurring occurred. Both versions seem musically equal. In the main text we give the version of the principal source, FC.

b. 77

composition: Op. 30, Mazurka in D♭ major

..

The cautionary flat to E is present in FE and EE. In FC one can see a deletion in this place, most probably of a ; however, in GE it was reintroduced.

b. 79-94

composition: Op. 30, Mazurka in D♭ major

12 staccato dots in FC

15 dots in FE

12 dots in GE1

13 dots in EE

16 dots in GE2

..

We give the staccato dots for the bass notes after FE, which is more accurate in this respect than FC (we add the only dot omitted by FE in bar 93 after FC). In GE1 and EE the versions of FC and FE, respectively, were inaccurately reproduced. All dots were added only in GE2.

b. 85-86

composition: Op. 30, Mazurka in D♭ major

No marks in sources

Accents suggested by the editors

..

We consider the missing accents, which are present in analogous bars 15-16, to be Chopin's inadvertence, since nothing indicates that – in spite of minor differences – the composer could have envisioned a different performance of bars 9-24 and 79-94.

b. 86

composition: Op. 30, Mazurka in D♭ major

..

In the main text we omit the Chopinesque but unjustified cautionary  to g1. It was only EE that omitted this accidental.
