2-a
2-eIt is difficult to say whether the shorter slur of AI defines an actual variant of articulation of this motif or – which, according to us, is more likely – whether it is inaccurate or erroneous (e.g. written with bar 81 in mind). The additional, short slur in FE (→GE1,EE) is most probably a mistake, perhaps caused by unclear notation of [A] (e.g. a correction to the rhythm and slurring present in AI two bars later). Its presence next to the longer, undoubtedly correct slur therefore probably resulted from the fact that the engraver did not finish implementing the corrections Chopin introduced while proofreading FE1 (the engraver added the correct slur, but did not remove the erroneous one). The shorter slur was considered erroneous and omitted also in GE2 (→GE3).
