b. 136-140

composition: Op. 42, Waltz in A♭ major

End of slur in FE0

Prolonged slur in FE1

Two slurs in FEG (→GE) & EE

..

In FE0 the slur ends on the minim. In the base text to FE1 it was corrected by extending the slur to bar 139 (there is a visible trace of deleting the original slur of FE0). There is no reason to doubt the authenticity of this change, yet in FEG Chopin completed the slurring differently, by adding the second slur in bars 136-140. The latter is also in EE, most probably based on the identical Chopin correction of the base text. Therefore, in the main text we give the version with two slurs, written by Chopin twice. The continuous slur of FE, offering greater flexibility as to the choice of phrasing, may be, however, treated equally.

b. 138

composition: Op. 42, Waltz in A♭ major

..

In FE there is no  returning a on the penultimate quaver. Chopin overlooked this error also in FEG, yet in GE1 (→GE2GE3) the correct revision was performed. The necessary sign is also in EE.

b. 139-140

Rest in FE

Tied sixth in GE & EE

..

The version of FE without the hold of the e-c1 sixth is earlier – in FEG (→GE) Chopin added the ties and a crotchet at the beginning of bar 140. An identical addition was most probably performed by him in the base text to EE. Due to this fact we adopt it to the main text. However, it should be mentioned that while proofreading the slurring of this phrase in FE1, Chopin ended the slur in bar 139 and did not add the hold of this sixth. Hence, the version of FE1 cannot be considered as definitely rejected.

b. 139-140

composition: Op. 42, Waltz in A♭ major

..

In GE1 the slur was erroneously led up to the 3rd crotchet, from which the new slur starts simultaneously. A relevant correction was performed already in GE2 (→GE3).

b. 141-142

composition: Op. 42, Waltz in A♭ major

a in FE, EE & GE2 (→GE3)

 repeated in GE1

..

The version of GE1, which does not sustain a, is attractive from the musical point of view, as repetition of this note underlines the distinctiveness of the melodically active middle voice. However, it is most likely that the missing tie is most probably the engraver's oversight, corrected in GE2 (→GE3). Cf. the adjacent note.
