The sources do not allow for a clear-cut determination of the intended by Chopin articulation and phrasing concerning the transition of bars 49 and 50. In the main text we give the version of A, as it is undoubtedly authentic and written faultlessly (unequivocal). The ambiguous version of FE may be interpreted in many ways; we give preference to the one in which the slur beginning in bar 50 remained unchanged, probably being a result of Chopin's correction (see bars 51-52). This is how the notation was interpreted in EE. Another one was adopted in GE and we present a third one as an additional possibility. category imprint: Differences between sources issues: EE revisions , Inaccuracies in FE , GE revisions |

The slurs of FE are unclear – in bar 49 (at the end of the line) the slur suggests a continuation, which is not confirmed by the slur in bar 50, beginning from the 1st semiquaver in the bar. It is probably a result of an error of the engraver of FE. In each of the editions based on FE the inaccuracy was handled in a different way (similarly as in the case of the slurs in the L.H.). In the main text we give the unequivocal version of A. category imprint: Differences between sources issues: EE revisions , Inaccuracies in FE , GE revisions |

Both slurs of A are moved to the right, which could have mislead the engraver of FE and then GE and EE. The slur of FE at the end of bar 52 (end of the line), suggesting a continuation, was considered in GE and EE to be correct, embracing both bars with one slur. In the main text we give the unequivocal, despite inaccuracies, slurs of A. category imprint: Differences between sources issues: EE revisions , Inaccurate slurs in A , GE revisions |
