Issues : Accidentals in different octaves

b. 66

composition: Op. 10 No 12, Etude in C minor

..

In A (→FE) there is no  lowering d2 to d2 in the 1st chord. A relevant accidental is also absent before the topmost note in the L.H. In GE and EE the flats were added, yet in EE3 only the one in the L.H. In the main text we remove the unnecessary  before d in the 2nd half of the bar, which appears in the sources.

A does not include the  before the topmost note of the chord on the 3rd beat of the bar. This patent oversight was completed in FE (→GE,EE). In turn, in all sources, except for GE3 (→GE4), there are unnecessary flats before c2 in this chord and before f2 on the 4th beat of the bar.

In A (→FEEE) there is no  lowering to d. This patent inaccuracy was corrected in GE. In the identical situation in bar 79  is included in all sources.

b. 81-82

composition: Op. 10 No 12, Etude in C minor

..

In A the naturals raising e to are written only before the topmost note of the chord at the beginning of bars 81 and 82 (also before in the R.H.) and the flats lowering to d (in different octaves) – only on the 2nd beat of bar 81. In FE before the lower note of the chord in bar 81 and flats of d on the 2nd beat of bar 82 were added to them. In GE all missing accidentals were added (also before d in the R.H.). In EE3 flats on the 4th beat of bar 81 were added (only in the L.H.) and on the 4th beat of bar 82 (both), while EE4 has accidentals in the same places as GE.
