b. 173

composition: Op. 42, Waltz in A♭ major

d1-e1 in FE (→FEGGE1)

d1-e1-g1 in EE & GE2 (→GE3)

..

The d1-e1 second featured in FE and GE1 is the original version, which is proven by the comparison with the remaining four analogous places in bars 49, 81, 113 and 269. In three out of five places Chopin added to it a gnote in FEG (→GE). In EE the completed version with the d1-e1-g1 chord is in all five places, which also proves Chopin's proofreading. Therefore, the fact of leaving the original version of the discussed bar in FE and GE1 must be considered as Chopin's oversight.

On the 2nd and 3rd crotchets in FE there is no c1. Chopin completed this deficiency in FEG (→GE). EE also features the correct version.

b. 182

composition: Op. 42, Waltz in A♭ major

B-d-g in FE0 (→FE,EE,FEGGE1)

e-g in GE2 (→GE3)

..

In analogous bar 10 Chopin changed the B-d-g chords for e-g thirds. He introduced this correction in all three base texts: in FEG (→GE), as well as in the base texts to FE and EE. Lack of respective changes in bar 182 is most probably a result of an oversight – Chopin was known to leave out a correction in one of a few similar places – therefore, also in this bar we give the corrected version with thirds, resulting in a lighter sound. The revisers of GE2 (→GE3) introduced the same change.

composition: Op. 42, Waltz in A♭ major

In FE0 there is no  next to d. The mistake was overlooked by Chopin in FEG (→GE1). The missing sign was already added in GE2 (→GE3) and FE1 and EE.
