b. 284-285

composition: Op. 42, Waltz in A♭ major

a & A in FE0

e & A1 in FE1 & FEG (→GE)

e & A1 in FED (L.H.)

a & octave in EE

..

Chopin changed the original version of FE0 to a more virtuoso one and with fuller sound in FEG (→GE) and FE. The different version of EE is most probably authentic as well, while the enhancement and expansion of the sound (with respect to the original version) was reached by the undoubtedly easier pianistic grip. In the main text we give the version of two editions, FE and GE, confirmed somehow by the entry in FED indicating to take over e by the L.H. (cf. bars 283-284).

b. 284

composition: Op. 42, Waltz in A♭ major

c2 in FE & GE

Third in EE

..

The third on the 1st quaver is certainly a mistake of FE0 (→EE) – Chopin corrected it in FEG (→GE) and in the finished FE.

b. 284

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

Slur to e2 in A

Slur to e2 in GE (→FEEE)

..

In the main text we give the version of A, in which Chopin marked the ending of the slur on the ecrotchet with a pronounced penstroke. The version of GE (→FEEE), probably proofread by Chopin, can be considered equal.

b. 284-285

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

Slur from f2 in A

Slur from e2 in GE (→FEEE)

..

The earlier beginning of the slur in the editions may be a result of the Chopin proofreading of GE1. However, not being certain thereof, in the main text we give the version of A.

b. 284-286

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

 in FE (→EE)

 in bar 285 in GE1 (→GE2)

 in GE3

..

In GE1 (→GE2), there is only one  in bar 285 instead of three subsequent  marks. There are no doubts that it is a mistake; however, it remains a mystery how such an accumulation of mistakes occurred (moreover, three out of four  in analogous bars 299-302 were overlooked). Perhaps some of them, e.g. those in bars 299-302, were added only just in the last proofreading of FE. GE3 added  in all five bars devoid of the marks.
