The ending of the slur over b. 30-31 is uncertain in A1: at the end of the line, in b. 30, the slur suggests continuation, yet there is no ending thereof in b. 31. A comparison with the slur in b. 26-27, extended by Chopin, proves that it is the missing ending of the slur in b. 31 that is a mistake. Such interpreted slurs are featured in FE2, which may be a result of Chopin's proofreading, since FE1 considered the slur in b. 30 to be inaccurate and shortened it correspondingly. In the main text we give the unquestionable four-bar slur of GE1, reflecting [A2] (in GE2 it was reproduced inaccurately: in b. 30, which ends the page, the slur reaches the minim only; see also b. 65-66).
