Issues : Inaccuracies in GE

b. 1

composition: Op. 25 No 10, Etude in B minor

in GC, EE & GE2 (→GE3)

in FE & GE1

..

The use of the  time signature is surprising only in GE1, as FE did not use the  indication in the Etudes – contrary to the manuscripts – even once, neither in Op. 25 nor in Op. 10 and in the Etude in F minor, Dbop. 36 No. 1 (cf. also the Impromptu in A major, Op. 29). Anyways, the correctness and authenticity of the  time signature is undeniable with respect to the compatible version of GC and EE.
The correct time signature returned in GE2 (→GE3).
Similarly in bar 104.

b. 15-16

composition: Op. 25 No 10, Etude in B minor

Two long accents in GC & EE

No marks in FE

Two short accents in GE

..

Lack of accents in FE must be considered as an inaccuracy, Chopin probably corrected this fragment (bars 15-21) in the base text to this edition less carefully – cf. notes to bars 17-1920 and 21). The short accents in GE are a result of misunderstanding the idea of the long accent by the engravers and revisers.

b. 17-19

composition: Op. 25 No 10, Etude in B minor

Eight long accents in GC

No marks in FE

Nine long accents in EE

Eight short accents in GE1

Nine short accents in GE2 (→GE3)

..

Lack of the accent at the beginning of bar 17 in GC (→GE1) at the beginning of bar 17 is most probably Chopin's oversight, who would add accents in these bars in GC. The sign is present in EE, whose base text was also probably completed by Chopin in this way. The accent was added in GE2 (→GE3) too. In FE there are no accents of dynamic character in bars 15-20.

In GE all accents were interpreted as shorts, contrary to the compatible, distinct notation of GC and EE (cf. the short accent in bar 20).

b. 24-25

composition: Op. 25 No 10, Etude in B minor

Two long accents in GC

No marks in FE

Short accents in EE & GE

..

In the main text we give differentiated accents, written most probably with Chopin's hand in GC. GE reproduced all of them as short ones, EE too.

b. 103

composition: Op. 25 No 10, Etude in B minor

Slur ended in GC, FE, EE & GE2 (→GE3)

Slur continued in GE1

..

The slur of GE1 is a consequence of literal interpretation of an inaccurate slur of GC in bar 104.
