a in FC (→GE) & EE2 (→EE3)

a in FE & EE1

It is hard to assume how the difference between the versions of FE and EE1 and these of FC (→GE) and EE2 (→EE3) occurred. In FC, the naturals introducing are written by the copyist, which means that they were present in the manuscript, probably an autograph copied by Fontana. Therefore, the absence of these signs in FE and EE1 could be explained by their later deletion by Chopin in the base texts to these editions. Hence a regular, chromatic progression of minor thirds in the middle voices would be then introduced only in bar 54 as a kind of variation of the repetition of this place. However, not being certain if it was so – the versions of FE and EE1 could have been results of mistakes – in the main text we give the undoubtedly authentic version of FC (→GE).

Crotchet c1 in FC (→GE), FE & EE3

Semiquaver c1 in EE1 (→EE2)

The missing crotchet stem in EE1 (→EE2), extending c1, is certainly a mistake, corrected in EE3.

GE1 does not include any accent in bar 68, whereas in EE1 (→EE2) there is no accent in the middle of bar 69 (similarly in bar 70). These patent errors were corrected in GE2 (→GE3) and EE3.
