The slurs in A, despite being added in fragments, were undoubtedly meant to create one continuous slur, running from the beginning of bar 16 to the middle of bar 23. However, in FE (→GE,EE), the slurs between bars 19 and 20 are clearly separated. Moreover, nothing indicates that the omitted in FE (→GE1) continuation of the slur in bar 21, certainly by inattention, was to be connected with the slur beginning in bar 22 (in EE and subsequent GE,s the slur in bar 20 ends on the last note). It is hard to attribute this discrepancy only to the engraver's distraction, on the other hand, it is uncertain what a possible Chopin's proofreading of slurs considered, whether the composer actually wanted to resign from one slur and divide it into two-bar phrases. In this situation, in the main text we give the certainly authentic slurring of A, subject to the fact that Chopin's latest decision could have been the divided slurs of the editions.
