b. 11

composition: Op. 25 No 11, Etude in A minor

..

In the 2nd half of the bar, the only accidental in the part of the R.H. in GC, FE and EE1 is a  raising d3 to d3. The notation, although inaccurate, determines also the sound of the 6th and 10th semiquavers in the 2nd half of the bar as d2 and d1. In turn, nothing indicates raising the 3rd, 7th and 11th semiquavers, which, in this situation, should read f3f2 and f1. This version, however, is impossible in this melodic and harmonic context – the use of g as delay of the fifth of the B7 chord requires f (possibly f) as resolution. The sharps raising the discussed notes to f3f2 and f1 were added in GE and later EE (in EE2 without  before the 11th semiquaver). Cf. bar 75.

In GC and FE there is no  raising g1 to g1. This patent oversight was corrected in GE and EE. Similarly in bar 76.

We add a cautionary  before f1 at the beginning of the bar after GE.

b. 16

composition: Op. 25 No 11, Etude in A minor

..

Before the 1st semiquaver of the last group, GC and FE have no accidental, which, due to the fact that 11 previous notes in the R.H. (together with d1) were written on the bottom stave, is only an inaccuracy. GE1 added a  before this note. In turn, the absence of this sign in EE1 (→EE2) and GE2 (→GE3) is a mistake, as in these editions – same as in mUltimate Chopin – the entire part of the R.H. is written in this bar on the top stave.

GC (→GE1) and FE repeated the  before b, the 2nd semiquaver of the last group. The unnecessary in this context sign was removed in EE and GE2 (→GE3).

b. 17

composition: Op. 25 No 11, Etude in A minor

..

The too early placed ending of the octave sign makes the 4th semiquaver of the 2nd half of the bar in FE sound as b1 instead of b2.
