b. 19

composition: Op. 25 No 6, Etude in G♯ minor

Both cautionary accidentals are an addition of the editors. The sharp before d2 is also in GE3.

composition: Op. 25 No 6, Etude in G♯ minor

..

Same as previously, FE, EE1 and GE1 misinterpreted the abbreviated notation of FC and remaining Stichvorlage manuscripts, giving the 2nd, 3rd and 4th groups of semiquavers without any accidentals. The mistake was corrected in EE2 (→EE3) and GE2 (→GE3).

Chopin did not introduce any accidental before the 3rd chord (which results from the compatibility of the version of FC and FE). Hence it is to be interpreted as g-b-f1. The version of GE1 with is undoubtedly erroneous – the reviser could have wanted to add a cautionary sign after the  lowering g1 to g1 at the beginning of the bar. In the same place, EE added a cautionary  (the sign could have been authentic, if it had already been in the base text to EE; however, an editorial revision is more likely). The mistake of GE1 was corrected in GE2 (→GE3), changing  before the bottom note for ; a cautionary  was also added before and another before e1 in the next chord.

The flat added in EE2 (→EE3) is undoubtedly an arbitrary revision. This version distorts the characteristic motif of repeated notes, appearing in each of the analogous phrases at least six times.

The patent error of GE1 could have been provoked by a slightly lower position of the head of this note in FC.
