b. 24

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

..

Between the 5th and 6th quavers in A one can see an unnaturally big gap and traces of deletion of something which had been written there. According to us, it could have been an originally envisaged additional chord, e.g., A-f-c1 in the L.H. and f1-c2-f2 in the R.H. It is striking that it does not seem that the deleted chord was supposed to be the last one in the bar, replaced then by another one – originally the bar included seven chords, the penultimate of which was eventually removed.

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).

The sources differ in the combination of cautionary accidentals used in this bar. A (→FE) has a  before d1 in the 1st chord and a  before e1 on the 5th quaver in the bar. In GE the  was omitted, while in EE – the . Moreover, in GE2 (→GE3GE4) and EE4 was added before a1 on the 2nd quaver. In the main text we also add a  before g2 on the 5th quaver.

The change of d1 to c1 in the chord on the 3rd quaver in the bar introduced in EE (there are visible traces of correction in print) is certainly an arbitrary change of the reviser who, presumably, followed the analogy from bars 27 and 29.

The cautionary flats before e2 at the beginning of bars 26 and 28 were added in a proofreading of FE (→GE,EE).
