b. 175-180

composition: Op. 2, Variations, complete

..

As was the case with the previous variations, In AsI variation III is practically devoid of performance markings – the only indication is the metronome tempo, compliant with the later sources.

b. 175-176

composition: Op. 12, Variations in B♭ major

..

In FE (→EE) in bars 175-176 in the L.H. the naturals were placed next to the d1 notes. It must be a mistake, since d1 does not require a  in this case; the only note that could require a natural would be b, in each of these bars. In the main text we include a respective correction, introduced by GE, as well as add cautionary flats to b1 at the end of the bars. The change in GE could be attributed to Chopin, as the sound of the FE version (→EE) does not provide any grounds for intervention. However, it is uncertain, as a careful reviser could have noticed the unjustified nature of the naturals to d1, described above, and found an explanation suggested by us, taking into account a few other cases of misplaced accidentals in FE.

b. 175-176

composition: (Op. 4), Sonata in C minor, Mvt I

..

In both bars the flats restoring b1 on the 5th quaver in the bar and the naturals restoring g1 on the 6th quaver are missing in A (→GEEE,IE). The accidentals were added only by FE.

b. 175

composition: (Op. 4), Sonata in C minor, Mvt I

Slur from 2nd quaver in A

Slur from first quaver in GE (→FE,EE,IE)

..

The change of the slur's range and place was an arbitrary decision of GE (→FE,EE,IE), in this case unjustified, according to us. See also the note in the next bar.
