b. 57

composition: Op. 30, Mazurka in D♭ major

..

In the main text we add cautionary flats to Gg1-e2 and e1. Both accidentals in the R.H. were also added in GE, together with a  to g. By contrast, in EE the version of the L.H. chords is wrong – there are naturals to the first one, hence their pitch is as follows: g-b-e1. It is most probably a mistake consisting in adding accidentals present before seemingly identical chords 2 bars earlier.

composition: Op. 30, Mazurka in D♭ major

in FC (→GE)

No indication in FE (→EE)

..

The absence of  in FE (→EE) could be Chopin's inadvertence (or the engraver's oversight). If this phrase (starting here) were to continue the previous dynamics ( from bar 49), the next  mark in bar 65 would be only a confirmation thereof, while the whole would be devoid of a dynamic contrast, so typical of opus 30, and particularly of this Mazurka. On the other hand, the absence of indications does not mean that one cannot play in a varied manner; it simply leaves the choice of performance details to the performer (to a greater extent). Therefore, the version without  may be considered an acceptable variant.

No sign in FC (→GE)

Our variant suggestion

..

In the main text we include the  hairpin present only in FE (→EE) in a variant form, since it is absent in the principal source, yet its authenticity is unquestionable; it can be considered a complement to the  indication.

b. 59

composition: Op. 30, Mazurka in D♭ major

No mark in FC (→GE)

Staccato dot in FE (→EE)

..

The easiest explanation for the missing staccato dot in FC (→GE) would be an oversight by the copyist – in the entire Mazurka a staccato mark on the 1st quaver in the bar is present in the vast majority of similar figures, thus constituting an element defining the Mazurka characteristic dance gesture.

b. 59

composition: Op. 30, Mazurka in D♭ major

..

In FE, in the top voice the double dotted crotchet is followed by a quaver. A comparison with analogous bar 63, and above all the FC (→GE) version, prove that the value of the last note is erroneous, since it is to be a semiquaver. An adequate correction was introduced in EE.
