b. 164-165

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE,FEG) there is no change to the bass clef here. The sign was erroneously added in GE1, by placing it only after the 1st crotchet in bar 165. Eventually, the error was corrected in GE2 (→GE3). EE also features the clef in the correct place.

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.

..

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

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.
