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

Fingering written into FES

Completed fingering from FES

Fingering in EE

No fingering in FE (→GE)

..

In the main text, we give the fingering written in pencil to FES (with one added digit for more clarity), coming most probably from Chopin. A different fingering, probably coming from Chopin, is in FESf. The poorly legible annotation in FEO may be interpreted in a variety of ways – we suggest these interpretations that lead to a pianistically natural fingering as variants.

The fingering in EE comes from the editor and it is inauthentic.

Slur from a in A, FE (→EE) & GE2

Slur from d1 in GE1

..

A later beginning of the slur in GE1 is an evident inaccuracy (the engraver made his work easier by avoiding an atypical slur). A slur compliant with the course of music was introduced both in FE (→EE) and GE2. The correction in FE could have been ordered by Chopin, but it remains uncertain.
