b. 30-31

composition: Op. 12, Variations in B♭ major

Slur in FE

No slur in GE & EE
..

It is highly unlikely that both GE and EE could have overlooked a clearly printed slur. Therefore, the slur was most probably added by Chopin in the last stage of proofreading FE.

b. 31

composition: Op. 12, Variations in B♭ major

..

In FE (→GE1) the accidentals on the 4th beat are missing. The undoubtedly overlooked  restoring g2 was added in EE and GE2.

b. 32-33

composition: Op. 12, Variations in B♭ major

Slur from g1 in FE (literal reading→GE,EE)

Slur from f1 suggested by the editors
..

The FE slur was printed inaccurately – it clearly starts before the crotchet in bar 33, but not before the bar line, hence in GE and EE it does not include the upbeat. A comparison with the slur over the repetition of this phrase in bars 34-36 proves that this interpretation is wrong. Slurs starting from the upbeat appear also in the opera's original score, both in the orchestral introduction and the solo part.

b. 33

composition: Op. 12, Variations in B♭ major

No indication in FE (→EE)

 in GE

Our variant suggestion
..

It is possible that  was added to GE by Chopin, hence in the main text we include it in a variant form. However, according to us, using this subtle kind of dynamics in this naturally simple theme seems to be excessive.

The  symbol present in the metronome marking in FE (→EE), corresponding neither to the beat nor to the movement unit (quaver), is most probably a mistake. Such situations occur in other pieces by Chopin as well, cf., e.g. the Andante spianato from Op. 22. Therefore, in the main text we provide , as it was already done in GE.
