b. 17-19

composition: Op. 25 No 3, Etude in F major

No signs in GC (→GE)

 in FE & EE

..

Both  signs (in bars 17 and 19) could have been accidentally omitted in GC (→GE) due to the placement of bars 17-20 at the end of the first page of the manuscript, devoid of any dynamic indications in the previous bars.

b. 19

composition: Op. 25 No 3, Etude in F major

Pedal change in GC (→GE1), FE & EE

No markings in GE2 (→GE3)

..

Omission of the pedal change on the 2nd beat of the bar in GE3 (→#GE4) combines with one pedal figures based on one harmony, which corresponds to Chopin pedalling of similar bars 21, 23 and 27, and in the broader sense also of bars 18, 20, 22 and 26. It cannot be excluded that Chopin overlooked bar 19 at the time of pedalling corrections (such corrections are visible in GC in bars 18 and 20-22; see also the note to bar 24). However, not being certain in this respect, in the main text we give the version which was actually written by Chopin.

b. 20-22

composition: Op. 25 No 3, Etude in F major

..

In GC there are no  signs at the end of bars 20 and 22, which, in this context, should be considered as inaccuracy. It resulted from self-corrections of Chopin, who changed the pedalling he wrote in these bars.

b. 20-24

composition: Op. 25 No 3, Etude in F major

..

The majority of the sources are missing some of the necessary cautionary signs (flats), which, however, only to the minimal extent impedes the correct interpretation of the text. As it can be concluded from the notation of FE, probably the closest to the notation of [A], Chopin generally omitted the sign next to the note, which already appeared in the same bar, with a relevant sign, one octave lower or higher (in the discussed fragment, FE lacks 12 flats). In GC and EE1 the notation is more precise, further additions were also introduced in EE2 (→EE3), yet only GE has a fully correct text. Similarly in bars 25-28.

b. 21

No marking in GC (→GE) & EE

in FE

Our variant suggestion

..

The  indication was most probably added by Chopin in a proofreading of FE. In the main text we give it in brackets due to its absence in the basic source (GC) and broader context of dynamic differences in the entire middle section of the Etude – see bars 17-19.
