b. 1-2

composition: Op. 25 No 5, Etude in E minor

No fingering in FC (→GE), FE & EE1

Fingering in EE2 (→EE3)

..

EE2 (→EE3) added fingering for three figures in the R.H. In spite of a clear accuracy, nothing indicates its provenience from Chopin.

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.
