Slurs

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

No slur in FE (→GE,EE)

Slur suggested by editors
..

In the main text we add a slur after the one present in the sources in an analogous figure in the 2nd half of the bar. The L.H. slurs in bars 129-131 include a few similar inaccuracies.

b. 133

composition: Op. 12, Variations in B♭ major

L.H. slur to b1 in FE (→GE,EE)

Slur to c2 & R.H. slur suggested by editors
..

Taking into account the 4 subsequent slurs in this and the next bar, always encompassing entire motifs, we consider the source L.H. slur to be inaccurate (one can assume negligence by the engraver or by Chopin in [A]). Therefore, in the main text we suggest a slur reaching c2; we also add a respective R.H. slur.

b. 136

composition: Op. 12, Variations in B♭ major

No slur in FE (→EE)

Slur in GE
..

There is no doubt that the omission of the slur in FE (→EE) was accidental – cf. the adjacent bars, particularly the first appearance of this phrase (bars 117-120). The slur was added in GE, perhaps at Chopin's request.

b. 138-140

composition: Op. 12, Variations in B♭ major

No slurs in FE (→GE,EE)

Slurs suggested by the editors
..

It seems unlikely that the absence of these two slurs in FE (→GE,EE) could indicate a change in the performance manner compared to the similar figures, hence in the main text we suggest adding them. The slur in bar 138 is modelled on an authentic slur in bar 120, while the slur in bar 140 on the slurs in the preceding bar, yet in this case we lead it to the end of the passage, as in bar 134.
