b. 216-217

composition: Op. 42, Waltz in A♭ major

..

The placement of crescendo differs slightly in particular sources. In FEG Chopin added cresc. under the last quaver in bar 216, and this is how it was reproduced by the engraver of GE1. In the next editions, GE2 (→GE3), the indication was moved slightly to the left, starting on the last quaver in bar 216. In EE the word crescendo was divided into syllables, which is a characteristic revision of the editor, and it was started at the end of bar 216. In the main text we adopt the indication of FE1, beginning in bar 217.

Fingering written into FEJ

No teaching fingering

The sign added in crayon in FEJ probably means the fingering number, '1'.

b. 217

composition: Op. 42, Waltz in A♭ major

..

In the entire bar FE0 (→FE,FEG) has only two cautionary accidentals: a  lowering g2 to g2 on the 3rd quaver and a  raising a1 to a1 in the L.H. Out of three undoubtedly overlooked signs in the R.H., it is the lack of the  raising a1 to a1 at the beginning of the bar that is most striking; the accidental was added in pencil in FED, it was also added in GE and EE. In both editions a  was added also before the last quaver, yet the fully correct notation is only in GE.

b. 218-219

composition: Op. 42, Waltz in A♭ major

..

In both bars in FE0 (→FE,FEG) there is not any  lowering g3(2) to g3(2). The flats in bars 217 and 220 prove Chopin's oversights, probably still in [A]. Some of the necessary signs were added in pencil by the composer in FED (both before g3) and in FEJ (at the beginning of bar 219). They were also added in GE and EE (the sign in bar 218 only in GE2 and GE3).
