b. 28

composition: Op. 10 No 6, Etude in E♭ minor

..

FE (→EE,GE1GE2GE3) has an additional  before g1 in the 1st chord. The unnecessary accidental was removed only in GE4 (→GE5). The layout of sharps in FE allows to claim that the  before gwas initially misprinted instead of the  raising b1 to b1. While proofreading this place, Chopin added only the necessary accidental, leaving the erroneous, yet not influencing the text, unchanged.

Crotchet in A

Our alternative suggestion

..

It is not clear at all if by leaving the 2nd half of the bar not entirely completed with rhythmic values in the upper voice, Chopin forgot about the dots extending the b1-dthird, as it was interpreted in FE (→GE,EE). Perhaps he planned to complete the bar with a rest, as in bar 26 (the scope of the figuration did not have to be the only reason for using a rest). We consider this possibility as an alternative solution.

C-c in A (→FEEE,GE1GE2GE3GE4)

C-c in FES & GE5

..

In A and the editions – except for one – there are no naturals before the 1st octave in this bar (nor a cautionary  before c2 in the middle of the bar). The harmonic context clearly indicates Chopin's oversight, which is confirmed by his entry in FES. The mistake was overlooked by the revisers until GE5.

Long accent in A (interpretation)

 in FE (→GE,EE)

..

We interpret the  mark as a long accent due to its position over the note and lack of the preceding it  mark. In the editions it was moved between the thirds of the upper voice, which was certainly performed by the engraver of FE.
