b. 656-657

composition: Op. 31, Scherzo in B♭ minor

d2 tied in A (→FCGE)

d2 repeated in FE (→EE)

The missing tie of d2 is most probably an oversight of the engraver of FE (→EE).

b. 656

composition: Op. 31, Scherzo in B♭ minor

Small crotchet in A (→FCGE1, →FEEE)

Acciaccatura in GE2 (→GE3)

..

In the main text we give the only authentic notation of the ornament, written in A. However, we accept the notation of GE2 (→GE3), since it almost certainly marks the same performance.

b. 657

composition: Op. 11, Concerto in E minor, Mvt I

..

FE (→EE, GE1 (→GE2) has a cautionary  before a before the 2nd chord in the L.H. It is a remaining element of the original notation of the 1st chord, in which there was an a​​​​​​​ instead of g (traces of a corresponding proofreading are clearly visible in FE). The accidental, unjustified in the final version, was removed in GE3. In GE1 (→GE2), cautionary naturals before c and c1, as well as before the c2 semiquaver, were added before that chord. We include all of them in the main text. A natural before c was added also in EE2 (→EE3), whereas in GE3 all accidentals before the 2nd chord were removed; only the  before c2 was left.

b. 657

composition: Op. 31, Scherzo in B♭ minor

 without  in A (→FEEE) & GE2 (→GE3)

with [] suggested by the editors

No  in FC (→GE1)

..

The missing  in FC (→GE1) is most probably an oversight of the copyist (in b. 206, of which the discussed bar is an exact repetition, added in GE2 (→GE3).
The missing  over the mordent must be an inaccuracy of Chopin: see b. 74.
