b. 55

composition: Op. 30, Mazurka in D♭ major

Quavers in FC (→GE)

Quaver & semiquaver in FE (→EE) & GE2

..

In the main text we give the FC (→GE) version. Although in analogous bars 49, 51 and 53 the second note is a semiquaver, the g2 quaver does not seem to be a mistake – together with the e2 note (prolonged due to the fact that it was played before), it is the quaver that constitutes an augmented version of the dotted rhythm opening the motif (). This rhythmic extension also impacts the next bar, which opens with a minim, and not with a crotchet. The semiquaver in FE (→EE) could have resulted from the engraver having misunderstood [A]; the engraver, influenced by the notation of bars 49, 51 and 53, considered the missing semiquaver beam to be a mistake.

Staccato dots in FC & FE (→EE)

No marks in GE

..

In FC the 'd' letters belonging to the  marks blended in these bars with the staccato dots under the bass notes, which resulted in the absence of dots in GE.

In FC there is no  to the top note of the L.H. chord on the 2nd beat of the bar (e1). The patent oversight – by the copyist or by Chopin – was corrected in GE; the correct text is also in FE (→EE).

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.

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.
