b. 237

composition: Op. 42, Waltz in A♭ major

 in EE, contextual interpretation of FEG

 in FE1

No marking in FE0 (→GE)

..

It is not clear what Chopin wanted to underline with the  mark: a sudden change of the chord at the beginning of the bar or the signal chord motif after the rest. The first possibility is suggested by the composer's entry in FEG (which was, after all, not included in GE) and the notation of EE, while the second one – by the notation of FE. It must be emphasised that even the fact of writing this mark under the rests, as it is in FE, does not exclude its validity from the beginning of the bar (possible examples of using such a manner – the Etude in C major, Op. 10 No. 1, bar 45 or in G, Op. 10 No. 5, bars 34-35).

Semiquaver in FE & GE

Quaver in EE

..

The version of EE was most probably introduced by Chopin in the base text to this edition. However, an error of the engraver or a revision of the reviser cannot be entirely excluded. Due to this fact, in the main text we give the version of FE0 (→FE,GE), drawn certainly from [A].

b. 237

composition: Op. 42, Waltz in A♭ major

..

There are no accidentals before the 2nd chord of the bar in FE0 (→FEG). This patent inaccuracy was corrected in FE1 (partially, as only a  before bwas added) and in GE1 and EE (both necessary naturals). In GE2 (→GE3) the third  before ewas added.

The fingering in the R.H. in bars 237 and 239 coming from Chopin was written – probably with the pupil's hand – into FED.
