b. 129

composition: Op. 12, Variations in B♭ major

Without 4 slurs in FE (→EE)

Slur in FEO & GE

Slur in GE & FEO

..

The absence of a slur in FE1 (→EE) is almost certainly an oversight, which is proven by both a comparison with the subsequent similar figures and the slur added in FEO. Therefore, we provide it directly in the main text. A slur was also added in GE.

b. 129

composition: Op. 12, Variations in B♭ major

No markings in FE1 (→GE,EE)

Accent in FEO

Our variant suggestion

..

It is highly likely that the accent in the FEO teaching copy was added by Chopin, hence we include it in the main text in a variant form.

Slur in FEO, possible interpretation

No sign in FE1 (→GE,EE)

..

The curved line entered in pencil into FEO could be interpreted as a slur indicating that the F chord opening this bar should be combined with the preceding D chord. We do not include this slur in the main text, as its meaning remains uncertain. In bars 129-131 in FEO there is a number of other marks, proving that this fragment was being thoroughly developed during lessons; only some of the marks can be interpreted accurately enough for them to be included in the main text or at least in the FEO transcription.

b. 130-131

composition: Op. 12, Variations in B♭ major

Slur from e to d1 in FE (→EE)

Slur from c to d1 in GE

3 slurs suggested by editors

..

We consider the missing slurs over the descending octave motifs to be an inaccuracy – cf. the slurs concerning the previous two motifs. The omission of 2 other L.H. slurs in bars 129-131 justifies the introduction of respective additions directly into the main text.
The GE version is most probably a mistake or revision.

b. 131

composition: Op. 12, Variations in B♭ major

..

The sources do not include a  to the last R.H. note, which is a patent inaccuracy, most probably committed by Chopin.
