b. 7-15

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

e1 in A

f1 & e1 in FE (→GE,EE)

f1 & f1 proposed by the editors

..

The change of the inner note in the 4th chord in bar 7 from e1 written in A to ffeatured in FE (→GE,EE) is most probably a result of Chopin's correction. The composer could have striven for a smoother combination of this chord with the next one, without a progression of parallel fifths. According to us, the correction intentionally concerns also two repetitions of this place, in bars 15 and 39 (Chopin omitted one of a few similar places at the time of proofreading on a number of occasions, e.g., in the Etude in G major, No. 5, bar 4).

b. 7-15

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

in A

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. 7-15

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

..

We add cautionary flats before the 2nd chord in bars 7 and 15 and a  before d2 in bar 17.

b. 8

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

 signs in A

 sign in FE (→EE)

No signs in GE

 
..

A includes two  marks, out of which only the 1st one was reproduced in FE (→EE). In GE there is however not a single one of them, which can indicate that even the one included in FE could have been initially overlooked and reintroduced by Chopin only during the last proofreading. In the main text we give both marks written in A, yet leaving the consideration of the second one, present only in the manuscript, at the performer's discretion.

b. 8-9

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

..

In the main text we adopt the quaver tie system applied by Chopin in A. In FE (→GE,EE) the ties in the L.H. may have been changed due to graphic difficulties, embracing three last quavers in bar 8 with one tie and providing the 1st quaver in bar 9 with a stem. In GE3 a similar tie system was applied in bar 8 also in the case of the R.H.
