b. 70

composition: Op. 12, Variations in B♭ major

Staccato dot in FE

No staccato dot in GE & EE

..

The fact that the staccato dot is missing both in GE and EE makes us ponder whether Chopin did not add it later – while proofreading FE, after having sent the copies serving as the bases for GE and EE.

b. 70

composition: Op. 12, Variations in B♭ major

No pedaling markings in FE (→GE,EE)

[ ] suggested by the editors

..

In the main text we suggest supplementing the pedalling after a similar situation in bar 80.

b. 71-73

composition: Op. 12, Variations in B♭ major

..

In bar 71 and 73, in FE the e quaver was printed under g1 in the R.H., as if it were supposed to be a semiquaver with the missing flag. A version with a semiquaver would be possible, but a non-simultaneous entry of the middle voices (e and c1) defining the new chord is highly unlikely. Therefore, we assume that it is the rhythmic value of the notes that is correct, and not their position. In GE only the mistake in bar 71 was corrected, while in EE in both places the synchronisation of the parts of both hands is inaccurate, with the difference in bar 71 being marginal, as a result of which the notation seems correct, whereas in bar 73 the shift of the e quaver is distinct enough for it to be reproduced as it was done in FE (in the version "transcript").

b. 71

composition: Op. 12, Variations in B♭ major

 under e in FE

at end of bar in GE & EE

..

The fact that the  asterisk was placed farther in GE and EE resulted from the erroneous alignment of the e quaver in FE – see the note above. In the main text we keep the synchronisation present in FE, that is a pedal release on this quaver, in accordance with the harmonic sense.

b. 71

composition: Op. 12, Variations in B♭ major

Slur from quaver in FE (→GE,EE)

Slur from semiquaver suggested by editors

..

Beginning the slur with the quaver d1-f1, as in the sources, is certainly an inaccuracy, perhaps repeated after [A] – cf. the corresponding slur in bar 73.
