b. 76-77

composition: Op. 49, Fantaisie in F minor

Overlapping slurs in A (likely interpretation) & FE (→EE)

Continuous slur in A (possible interpretation→GE)

..

In A the slur in bar 76, last in a line, suggests that it should be continued, which is not confirmed by the slur at the beginning of bar 77. The comparison with analogous situations in bars 163-164 and 243-244, which are not at the beginning or end of a line in A, does not make it easier to guess Chopin's intention, since in bars 163-164 there is a continuous slur, whereas in bars 243-244 the slur is divided. In this situation, to the main text we adopt the FE solution, which could be considered compromise – the slurs meeting on the 1st quaver in bar 77.
Similarly, in bars 80-81.

b. 76

composition: Op. 49, Fantaisie in F minor

No slurs in sources

Slurs suggested by the editors

..

In the main text we suggest slurs modelled on analogous bar 163 – see bars 68-75.

b. 77

composition: Op. 49, Fantaisie in F minor

..

In the main text we include the cautionary  to e1 added – perhaps at Chopin's request – at the stage of proofreading FE2 (→EE).

b. 77-82

composition: Op. 49, Fantaisie in F minor

..

In A (→FE1) there are no flats restoring d3 in bar 77 (5th quaver) and e3 and e2 in bar 78 and 82 (2nd quaver from the final triplet in the top voice). These patent inaccuracies, typical of Chopin, were corrected in GE and FE2 (→EE).

b. 77

composition: Op. 49, Fantaisie in F minor

L.H. slurs in A (→GE) & EE2

No slurs in FE (→EE1)

..

The slurs were probably added to A after [FC], on which FE was based, had been finished. In EE2 they were added after comparing it with GE1.
