b. 248-249

composition: Op. 42, Waltz in A♭ major

cresc. in bar 248 in FE

cresc. in bar 249 in GE & EE

..

In FE1 the crescendo indication was placed – most probably after the proofreading entry of Chopin – already in bar 238. In the main text we adopt the version of FEG (→GE) and EE

b. 251

composition: Op. 42, Waltz in A♭ major

in chord in FE0 (→FE1,FEG,EE)

b in chord in GE

..

On the 3rd crotchet GE certainly erroneously repeats the previous chord.

b. 253

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE,FEG) there is no  lowering g to g. It was the reviser of GE1 (→GE2GE3) that added the necessary sign. The correct version is also in EE.

b. 255

composition: Op. 42, Waltz in A♭ major

..

GE1 has a superfluous cautionary  next to g1 on the 3rd crotchet. The sign was removed already in GE2 (→GE3).

b. 256

composition: Op. 42, Waltz in A♭ major

g2 in FE0 (→EE)

f2 in FE & GE

..

The version of FE0 (→EE) with g2 as the bottom note of the first of the pairs of the quavers is most probably erroneous. In the base text to FE and in FEG (→GE) Chopin changed this g2 to f2, yet in FE the correction was misunderstood, hence the flat was also copied, which resulted in a f2. Chopin corrected this new error in FEJ. In this situation, the presence of the original version in EE must be considered as a result of an oversight of proofreading or the engraver's inattention. In the main text we give the text written by Chopin's hand in FEG and FEJ.
