b. 1

composition: Op. 25 No 8, Etude in D♭ major

in A (→GE)

in FE & EE

..

The use of the  time signature is surprising only in EE, as in FE the  time signature was not used in the Etudes even once – contrary to the manuscripts – neither in Op. 25 nor in Op. 10, in the Etude in F minor, Dbop. 36 No. 1 (cf. the Impromptu in A major, Op. 29). Anyways, the correctness and authenticity of the  time signature written by Chopin in A (→GE) is beyond any doubt.

b. 1-6

composition: Op. 25 No 8, Etude in D♭ major

Chopin's intention of providing all bass notes with staccato dots remains beyond any doubt, despite the fact that in A the last dot is missing (or it is written in an unclear manner). It is FE and GE2 (→GE3) that include the totally correct notation in this respect. In the remaining editions, the notation is more or less inaccurate – GE completely omits the dots in these bars, while EE puts them only next to a few notes, rather accidentally (one dot was omitted in each of the following bars: 1-3 and 5-6).

We add cautionary flats before the 2nd sixth in bars 2 and 6.

Fingering in A (→GE)

Fingering in FE & EE2 (→EE3)

No fingering in EE1

Our suggestion

It is one of rare cases of Chopin's giving a clearly different fingering for the same fragment. In the main text we include them both – directly over the notes we give the fingering of FE, probably added by Chopin while proofreading (it does not include the 10th quaver of the bar); the fingering was then repeated in EE2 (→EE3). The top fingering, together with the numerals concerning the 9th and 10th sixth comes from A (→GE). In EE1 there is no fingering in this bar.

GE1 has a g as the bottom note on the 6th quaver. The comparison with the remaining sources, featuring e, proves that the Terzverschreibung error was committed here, yet, on the basis of GE1, one could also suspect an omission of .
