Slurs in AT

Slur in AW, CDP, GC (→GE), FE & EE

..

AT has a clearly different slurring here, reflecting, to a significant extent, the structure of the phrase: the upbeat is not included in the phrasing slur, while above each bars 1-2, there is a separate slur. Cf. bars 6-8, 9-10, 16-17, 18-20.

The values of the metronome tempo, both 120 in A and 160 in FC, were written with Chopin's hand, it was most probably also the case in the manuscript base text to EE. Therefore, in the main text we give 160, present in two authentic sources.

The use of  time signature is not surprising only in GE1, as FE does not use the  indication in the Etudes – contrary to the manuscripts – at all, neither in Op. 10 nor in the Etude in F minor, Dbop. 36 No. 1 (cf. also the Impromptu in A major, Op. 29). In any case, the correctness and authenticity of the  time signature does not raise any doubts thanks to A (→FC). The correct time signature was returned in GE2 (→GE3).
