b. 155-156

composition: Op. 49, Fantaisie in F minor

Pedal in A (→GE) & EE2

No markings in FE (→EE1)

Our variant suggestion

..

We provide the whole-bar A pedal mark (→GE), the only indication written here by Chopin, as the principal pedal mark. However, as in a similar context in bar 68 Chopin provided two pedalling variants, we suggest the version with a half-bar pedal mark, in this case absent in FE (perhaps due to an oversight), as an alternative solution.

b. 155-159

composition: Op. 49, Fantaisie in F minor

Slur in A (→GE)

No slur in FE (→EE)

..

In the main text we give the slur added to A (→GE) after [FC] had been finished. In FE (→EE) the slur is absent, as in analogous bars 68-72. See also bars 160-163 and 164.

b. 155-165

composition: Op. 12, Variations in B♭ major

..

In this entire fragment, in the key of D minor, in FE 9 out of 21 necessary naturals raising e to e, in different octaves, were omitted. In GE and EE some of them were added. The context rules out any doubts as to the sound of the notes devoid of naturals. In bars 166-167 3 more naturals were omitted.

b. 155

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

  in A, possible interpretation

 in GE (→FE,EE,IE)

..

When interpreted literally, the A dynamic markings seem contradictory –  is already under the 2nd crotchet in the bar, hence there is no point of reference for . In the content transcription of A (version "edited text") we relate  to the L.H. minim, which can be considered a suggestion for independent dynamics in the parts of both hands in the following bars.
However, we believe that the most convincing, both in terms of sources and music, explanation of the A notation is the following:  is the initial version, left by inattention after having introduced later markings, that is  and . We provide the resulting version, compliant with the GE text (→FE,EE,IE), in the main text.

b. 155-156

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

..

In A in bar 155 Chopin wrote flats only to d1 in the R.H. and to d in the L.H. The remaining necessary accidentals were added in GE (→FE,EE,IE). In A in bar 156 there is only one  to g2. The other necessary  was added in EE1 (→EE2) and in the remaining editions.
