b. 23

composition: Op. 12, Variations in B♭ major

..

In the main text we add a cautionary  to f3 at the beginning of the bar.

b. 25

composition: Op. 12, Variations in B♭ major

Wedge in FE

Staccato dot in GE

No markings in EE

..

The missing mark in EE is most probably an oversight. By contrast, the change of the wedge to a staccato dot in GE resulted from general revision carried out in this edition – see the note in bar 7.

b. 25

composition: Op. 12, Variations in B♭ major

Slurs in FE (→GE)

Slurs in EE

Our suggestion

..

The inconsistent slurs in FE (→GE) are most likely inaccurate, perhaps due to imprecise notation in [A]. In the main text, we standardize slurs according to the division into hands indicated by the graphic layout. An attempt at partial standardization was also made in EE.

b. 26

composition: Op. 12, Variations in B♭ major

Without slur or wedge in FE

Slur & staccato dot in GE

Slur & wedge in EE

..

In FE the second rhythmic group in the L.H. part is provided neither with a slur nor with a wedge, which is either the engraver's oversight or Chopin's inadvertence. The marks were added in GE and EE, yet in GE the wedge was changed to a staccato dot as part of general revision – see the note in bar 20.

b. 26-27

composition: Op. 12, Variations in B♭ major

..

In the main text we add cautionary accidentals – naturals to d3 and d2 in the L.H. part and a  to e3 and a  to a2 in the R.H. part. On the other hand, we omit the poorly justified  to a1 at the end of bar 27, present in all sources.
