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.

b. 658

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

e & e1 in FE (→GE,EE)

e​​​​​​​ & e1 in FES

..

On the basis of the available sources, one cannot determine whether Chopin chose one version of the 1st note of bass, and if yes then which one. In FE (→GE,EE), there is an e-e1, left unchanged by Chopin in four out of five pupil's copies, including two that bear visible traces of this movement of the Concerto having been studied with Chopin (FED and FEH). However, in FEorch (→GEorch) cellos have an e1, and in FES, flats before the 1st chord are added, whose shape does not exclude Chopin's hand. Since both versions seem to be authentic, we choose to the main text the one that is presented by the principal source, i.e. FE.
