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. 24

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

..

In A there is no  before the topmost note. It is a result of an oversight in the change of notation of this chord from f1-c1-f2 to e1-c2-e2. The accidental was already added in FE (→GE,EE).

b. 49

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

Chord with c1 in A

No c1 in chord in FE (→GE,EE)

..

Lack of c1 in the 5th chord is most probably a result of an oversight of the engraver of FE (→GE,EE). Although in FE there are visible traces of corrections in this chord, yet the note was deleted, probably printed by mistake instead of f. In the main text we give the unequivocal version of A, compliant with analogous bar 48.
