In A of this Etude Chopin wrote only the following opus number instead of a title, which certainly does not equal the fact that he wanted to waive the name Etude used in the autographs of other etudes (No. 5-8 and 12). In the main text we give the title and dedication in the undoubtedly authentic version adopted in FE. The extensions of both the title (in GE and EE) and the dedication (in EE) most probably come from the editors. See the Etude in C major, No. 1, bar 1.

b. 1

composition: Op. 10 No 11, Etude in E♭ major

 in A

 in FE (→GE,EE)

Our variant suggestion

..

In the version for publication the dynamics of the Etude remains undefined until bar 26. Although Chopin could have accepted this state of affairs, it seems right to give the hint written in A (in a variant form) in the main text.

b. 7-15

composition: Op. 10 No 11, Etude in E♭ major

No indication in FE (→GE,EE

Our variant suggestion

..

Not being certain whether the missing cresc. indication in bars 7 and 15 in the editions corresponds to Chopin's intention, we suggest a variant solution in the main text.

b. 17-25

At the beginning of bars 17, 19, 23 and 25 A includes  indications, while in bar 21 – . In the editions all  marks were omitted and instead of  there is . Due to the fact that all other dynamic indications in these bars were more or less accurately reproduced, it seems highly unlikely that the changes had not been accepted and partially introduced by Chopin. Therefore, in the main text we leave the version of FE (→GE,EE) without any additions. The version of A may be considered as an alternative one.
In bar 21 the erasure visible in A allows to conclude that originally Chopin most probably wrote there .

b. 18-24

composition: Op. 10 No 11, Etude in E♭ major

three times in A

three times in FE (→EE)

two times in GE

..

The missing dashes limiting the range of cresc. in bars 18-20 and 23-24 is a very common defect of the first editions of Chopin's works. Moreover, in GE there is no cresc. in bar 18, which also must be considered as a mistake.
