In the main text we give the title and dedication in accordance with the title page of the entire opus in FC and FE.
See the Etude in A major, No. 1.

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).

According to us, placing  in A only at the beginning of bar 1 is an example of Chopin's using a manner of putting the indications inside, and not at the beginning of, the area of their validity, which is not used at all today. It is also possible that Chopin feared the suggestion that the indication refers only to the L.H., yet this risk also seems to be negligible in our times. In FC Fontana put the sign slightly earlier, so that in GE1 it was printed at the very beginning of the piece. The interpretation was reviewed in GE2 (→GE3).

The pair of   hairpins must have been added by Chopin in FC and base text to EE. Nothing indicates that Chopin could have wanted to resign from these indications – their absence in A (→FE) is almost certainly a result of haste and insufficient attention at the time of parallelly introducing corrections and additions in three Stichvorlage manuscripts. Similarly in bars 6-8.
Shortening the  sign in GE2 (→GE3) is most probably an editorial revision or a mistake of the engraver.
