The fingering of the R.H. added by Fontana in EE seems to be accurate, although it is not the only possibility and it does not arise from Chopin's fingering. category imprint: Differences between sources issues: EE revisions |

The slur of A in the 2nd half of bar 8 may suggest a continuation in the next bar, in which there is no possible ending of the mark. category imprint: Differences between sources issues: Inaccurate slurs in A |

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. category imprint: Differences between sources issues: Errors in EE |

The version of A (→FE) is almost certainly erroneous. It is revealed by the notation of AI in this bar and a compatible version of all sources in analogous bar 44. The correct text of GE and EE is most probably a result of revisers' actions, probably on the basis of comparison with bar 44. category imprint: Differences between sources issues: EE revisions , Terzverschreibung error , GE revisions , Errors of A |
