b. 168-176

composition: Op. 42, Waltz in A♭ major

Thirds in the sources

Permissible variant with sixths

..

Assuming a possible authenticity of the variants of EE in analogous bars 44, 52, 76 and 84, one has to allow application of this version also in bars 168 and 176.

b. 170

composition: Op. 42, Waltz in A♭ major

..

On the 4th quaver GE1 has an erroneous g3. This typical Terzverschreibung of the engraver was already corrected in GE2 (→GE3).

b. 172

composition: Op. 42, Waltz in A♭ major

e1 in FE

Third in GE & EE

..

On the 2nd crotchet in FE0 (→FE) there is no c1, probably as a result of a misinterpretation of the autograph. Chopin added this note in FEG (→GE) and in the base text to EE.

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.
