Slurs

b. 139-140

composition: Op. 12, Variations in B♭ major

Slurs over demisemiquavers in FE (→GE,EE)

Slurs to quavers suggested by editors

..

According to us, it is more likely that the [A] slurs were inaccurately written or interpreted than they were shortened in relation to the similar motifs in bar 121 and 123. Therefore, in the main text we provide slurs modelled after the aforementioned bars.

b. 141

composition: Op. 12, Variations in B♭ major

3 slurs in FE (→EE)

2 simultaneous slurs in GE

2 succesive slurs in EE

4 slurs suggested by editors

..

The coincidence of triplet and motivic slurs in FE prompted the revisers of the remaining editions to intervene (the GE version could have resulted from a mistake). In the main text we suggest adding a second motivic slur over the part of the figure performed by the R.H., keeping the triplet slurs, as an exception, which in this case help one navigate the rhythmic structure of the figuration, different from the division into hands.

b. 187

No slur in FE

Slur in GE & EE

..

The missing slur must be considered a defect of notation. Therefore, in the main text we include the slur added in GE and EE.

b. 199

composition: Op. 12, Variations in B♭ major

Slurs over semiquavers in sources, literal reading

Slurs over whole motives suggested by editors

..

According to us, the slurs in the sources resulted from the FE engraver having misunderstood [A]. It is difficult to assume that Chopin would have wanted to pay a particular attention to the 3 middle notes of the bottom voice figure with the help of slurs, omitting the thematic top voice. It is most likely that the slurs in [A] were between the top voice notes and referred to the top voice, covering the entire bottom voice figure as well.
The same applies to bars 203-206.

b. 200

composition: Op. 12, Variations in B♭ major

No slur in FE (→EE)

Slur in GE

..

The missing slur must be due to Chopin's inadvertence or the FE engraver's oversight (→EE). The slur added in GE could be coming from Chopin, yet such an addition could have also been performed by the reviser.
