b. 31

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

No markings in GC (→GE) & FE

Pedal change in EE

..

Similarly as in bar 24, one group of sources (EE) has a pedal change here, omitted in other sources. Most probably, it is the original version, overlooked by Chopin at the time of introducing corrections.

b. 37-40

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

  in GC (→GE) & GE

Our variant suggestion

..

In EE, this four-bar section is provided only with  signs. The absence of  signs in bars 38 and 40 cannot be, however, considered as a mistake, as Chopin, in a similar way – with a pair of  signs – marked analogous bars 17-20. Therefore, it cannot be excluded that in bars 37-40 it is exactly the version of EE that corresponds to the final intention of Chopin. As the sources do not give basis for a clear conclusion, in the main text we suggest  signs in brackets, leaving their consideration at the discretion of performers.

b. 40

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

..

In GC, FE and EE1, there are no naturals before the 1st semiquaver and 2nd quaver in the R.H. (g1 and d2). Both patent inaccuracies were corrected in GE, whereas in EE2 (→EE3) and FES, only the first of the signs was added, the  lowering g1 to g1.

b. 40

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

..

In EE1 (→EE2), there is no  before the 4th quaver in the bar (a1). This patent inaccuracy was corrected only in EE3.

b. 41-44

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

..

Similarly as in bars 20-24, in the notation of [A] – for the notation of the autograph we consider the compatible version of GC and FE – seven necessary accidentals (naturals) are missing, which, however, does not impede the correct interpretation of the text. In EE1 (→EE2), the notation is already more accurate (in relation to GC and FE 2 signs were added, in the R.H. in bar 41), while the next 3 naturals were added in EE3. GE has the correct version, yet in GE1 there are no signs in the 2nd group in bar 43, which, from the graphical point of view, is the same as the previous one (repeating the signs in such situation is a question of convention).
An inaccurate notation is also present in two subsequent bars.
