b. 17-18

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

..

In FC (→GE1) and FE there are no sharps returning d2 and c2 in the last group in bar 17 and c2 at the end of bar 18. EE and GE2 (→GE3) include the correct notation, which, in both cases, is a result of an editorial revision – in EE it is likely, in GE2 – certain.

In FE in both bars the 2nd, 3rd and 4th groups of semiquavers are written in an abbreviated manner as repetition of the first.

It is hard to state how the difference between FC (→GE) and EE1 was created – it may be a result of Chopin additions to the base texts to EE (cf. bars 17-18) or Fontana's oversight. The additions were introduced by Chopin most probably in the proofreading of FE, they were also repeated in EE2 (→EE3).

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.

b. 20

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).
