b. 261

composition: Op. 42, Waltz in A♭ major

..

In all base texts Chopin added a  sign. In GE2 (→GE3) this very characteristic for Chopin indication was changed to , used by the composer only occasionally.

b. 261

composition: Op. 42, Waltz in A♭ major

Pedalling in FE1

No pedalling in FE0 (→EE,FEGGE)

..

The pedalling in this bar was written by Chopin only in the proofs of FE. Similarly in bars 273-276.

b. 261

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

Accent in A & GE2

No mark in GE1 (→FEEE)

..

The missing accent is certainly an oversight of the engraver of GE1 (→FEEE).

b. 261-263

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

cresc. - - in A

cresc. in GE & EE2 (→EE3)

No indication in FE (→EE1)

..

We give the cresc. marking, together with the dashes marking its range, after A (see also bars 263-264). In GE the marking was put slightly further and the dashes were overlooked, whereas FE (→EE1) does not have it at all. The absence of the indication in FE could be explained by a mistake of that edition or by a repetition of the original error of GE1, which was corrected in GE1 only in the last phase of proofreading. The indication was added in EE2 (→EE3) on the basis of comparison with GE1.

b. 261-264

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

2 two-bar slurs in A

4 one-bar slurs in GE1 (→FEEE)

1 four-bar slur in GE2

..

In the main text we give the unquestionable two-bar long slurs of A. Both the division of the slurs in GE1 (→FEEE) and their combination in GE2 must be arbitrary changes – a typical manner of the engraver of GE1 and a revision (without any apparent reason) of GE2
