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.
