b. 121-123

composition: Op. 12, Variations in B♭ major

Slurs to quaver in FE (→GE)

Slurs over demisemiquavers in EE

..

The shorter slurs over the demisemiquavers in the 1st halves of bar 121 and 123 most probably resulted from routine revision performed by EE – the slurs were adjusted to the demisemiquaver groups and brought into line with the slurs at the end of these bars.

b. 123

composition: Op. 12, Variations in B♭ major

..

In the main text we include the  raising g1 to g1 added in GE, although it is uncertain whether it was performed at Chopin's request. In the harmonic language of this variation, the use of an altered dominant in this model cadence in F minor would be inconceivable.

b. 123

composition: Op. 12, Variations in B♭ major

No slur in FE (→GE,EE)

Slur, our variant suggestion

..

Taking into account the slurs in analogous bar 121 and the relatively numerous inaccuracies and omissions concerning slurs in the Variations, in the main text we suggest adding a slur over the demisemiquaver group. We provide the slur in brackets, as the different melodic motif used in this group and the presence of ritenuto mitigate the parallel nature of the endings in bar 121 and 123.

b. 125

composition: Op. 12, Variations in B♭ major

 in FE (→EE)

No markings in GE

..

The absence of the mark in GE probably results from the fact that Chopin entered it into FE (→EE) later, while proofreading, after the copy that served as the basis for GE had been sent. It is proven by a different font of the letter than in the remaining places in the piece.

b. 125-127

composition: Op. 12, Variations in B♭ major

Markings only in b. 127 in FE (→EE)

No markings in GE

Markings in both bars suggested by editors

..

The absence of markings – dots under the slur – in bar 125 must be considered an oversight, since the chordal motifs in bar 125 and 127 must be performed using the same kind of articulation. Therefore, in the main text we suggest adding respective markings. The easiest explanation for their absence in GE in bar 127 is the engraver's carelessness.
