Slurs in AI, A (→FEGE) & EE4

No slurs in EE3

..

Lack of slurs in EE3 is certainly an error. The slurs in EE4 were added as a part of far-reaching additions, including bars 2-16 (cf. also the note to bars 9-16).

In both autographs, the slur in the 1st half of the bar does not embrace the extreme semiquavers, which is almost certainly only an inaccuracy of the notation. From the formal point of view, AI has such a slur also in the 2nd half of the bar, which in this manuscript is briefly marked as a repetition of the 1st.

In EE there is no  returning f2 (despite the presence of – as in the remaining sources – cautionary  before g2). It is most probably an oversight of the engraver or copyist performing the base text to EE.

Same as in bar 4, FE, EE1 and GE1 misinterpreted here the abbreviated notation of FC and of the remaining Stichvorlage manuscripts, giving the 2nd, 3rd and 4th group of semiquavers without any accidentals. The mistake was corrected in EE2 (→EE3) and GE2 (→GE3).

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).
