composition: Op. 42, Waltz in A♭ major

e1 in FE

Third in GE & EE

..

composition: Op. 42, Waltz in A♭ major

d1-e1 in FE

d1-e1-g1 in GE & EE

..

The d1-e1 second in FE is the original version – in FEG (→GE) Chopin added a gnote to it. EE also has the completed version with the d1-e1-gchord. Therefore, the fact of leaving the original version in FE must be considered as Chopin's oversight.
