Slurs in AI, contextual interpretation

FE (→GE,EE)

..

It is unclear whether the slurs of AI are an inaccurately written version of whole-bar slurs of the first editions or whether they were meant to be shorter in Chopin's intention, embracing only these three notes. We adopt the second interpretation, taking into account the fact that the undoubtedly whole-bar slur in bar 15 in AI is clearly longer. Cf. bars 63-65.

Dotted minims in FE (→GE,EE)

..

Plain minims in AI most probably represent inaccurate (simplified) notation of the ultimate version, and not a different version. Similarly in bars 63-66.
