b. 4

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

No e in chord in A

Chord with e in FE (→GE,EE)

..

The origin of the additional e note present in the 1st chord in the bar in FE (→GE,EE) is unclear. Chopin could have added it at the time of proofreading FE, yet it seems more plausible that it was printed by mistake instead of (Terzverschreibung) or B (the second possibility is indicated by the length of the arpeggio wave). Then the correct note was added, yet the erroneous one was not deleted, which is a characteristic error of engravers (the then printing technique made adding a note much easier than deleting it). Similar mistakes were often committed in other Chopin's works, e.g., in the Scherzo in B minor, Op. 20, bars 135 and 292, the Ballade in G minor, Op. 23, bar 171 and the Polonaise in A major, Op. 40 No. 1, bar 93. Cf. the remark concerning the Etude in G major, No. 5, bar 59.

b. 4-12

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

..

In A in bar 4 (and bar 12, which repeats this bar) the  hairpins embrace with their range the 2nd and 3rd chords in the bar. This is how it was more or less reproduced in FE, yet minor inaccuracies caused that in GE the sign in bar 12 was given a form of an accent, while in EE in both bars it was printed one quaver too early.

b. 4-12

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

 in A

 cresc. in FE (→EE)

..

In the main text we give the  combination in the 2nd half of bars 4 and 12 on the basis of A, as nothing indicates that the visible in the editions changes of arrangement and, above all, separation of the hairpins from the verbal indication were performed by Chopin.

b. 5-6

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

..

In A there are visible traces of a change of the bottom note in the 3rd chord in bars 5-6 (as well as in bars 13-14, which are marked in an abbreviated form in A as a repetition of bars 5-6). Originally, all the places featured c2, hence Chopin proceeded from the strictly analogous version to bars 1-2. Cf. bars 37-38.

b. 6-7

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

Slurs in A

FE (→GE1), interpretation

GE2 (→GE3GE4)

Our suggestion

..

The slurs of A in these bars are inaccurate, which was only partially corrected in FE (→GE1). The ambiguity was eliminated in EE and – in a different way – in subsequent GE,s, yet Chopin did not participate in their elaboration. Taking into account analogous bars 14-15, in which Chopin probably corrected the slur, and 38-39, in which he combined the slurs in A, in the main text we suggest a continuous slur from the 2nd quaver in bar 6 to the middle of bar 8.
