b. 1

composition: Op. 35, Sonata in B♭ minor, Mvt I

in GC (→GE) & EE2

in FE (→EE1)

..

The  time signature in FE (→EE1) is almost certainly a result of inattention or manner of the engravers of FE, who in numerous pieces by Chopin seemed not to differentiate between  and  – see the Etudes, Op. 10 or the Impromptu in A major, Op. 29. Therefore, in the main text we give , written in GC (→GE), whose correctness and authenticity do not raise any doubts. This time signature – probably under the influence of GE – was introduced also in EE2.

b. 1

composition: Op. 35, Sonata in B♭ minor, Mvt I

in GC & GE2

No marking in FE (→EE) & GE1

..

The absence of  in FE (→EE) must be considered an inaccuracy of notation. Most likely, it is a non-corrected oversight of the engraver, although one cannot entirely exclude the possibility that the sign was added by Chopin in GC. In turn, no  in GE1 is a patent oversight. See also bars 5 and 18-19.

b. 1-2

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

The slur embracing the bass motif, visible in GC (→GE), was probably overlooked by the engraver of FE1 (→FE2EE1). It was then added in the proofreading of FE3 (→FE4), probably as a result of Chopin's intervention. The sign was also added in EE2.

b. 2-3

composition: Op. 35, Sonata in B♭ minor, Mvt I

 in GC

Longer  in FE (→EE)

No mark in GE1

Shorter   in GE2

..

According to us, out of two sources based directly on [A] – GC and FE – it is the copy that may convey a more accurate representation of this place in the autograph, since the text in FE is too tightly packed.

b. 3

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In FE1 there is no top note of the chord, d1. The mistake was corrected in FE2; all the remaining sources also include the correct text.
