b. 283-285

composition: Op. 42, Waltz in A♭ major

 in bar 283 in FE

 in bar 285 in EE

FEG (→GE)

..

In each of three editions Chopin marked the ending of crescendo differently. The version of EE – if it reproduces Chopin's notation correctly – may be considered as intermediary between the shorter crescendo in FE and longer in GE. In the main text we give the version of FEG (→GE) written with the composer's hand.

b. 283-287

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

g in chord in GC (→GE)

b in chord in FE (→EE)

..

It is one of the places in which the performance and concert tradition, shaped to a significant extent on GE and established by the deeply rooted for many decades belief that GC is Chopin's autograph, most probably conveys an erroneous text. The absence of visible corrections in the sources based directly on [A] – GC and FE – means that one of the versions is most probably erroneous. The significant majority of arguments supports the correctness of the chord with b, which we thereby give in the main text.

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

No markings in GC & FE (→EE)

The pedalling of the five final bars is most probably an arbitrary addition by the reviser of GE.

composition: Op. 21, Concerto in F minor, Mvt I

Crotchet b1 in A & GE2

Dotted quaver bin FE (→EE)

We consider the change of the rhythm in GE1 (→FEEE) to be almost certainly inauthentic – see bar 135.

We consider that the subtle improvement introduced by Chopin in the proofreading of FE in the analogous bar in the exposition is valid also here. Chopin would often overlook proofreading of one of a few similar places.
