b. 45-46

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

GC and FE lack two flats before as notes in various octaves, while EE – one. These patent inaccuracies do not impede the correct interpretation of the text at all and they were corrected in GE (similarly as in bar 43 in GE1 there are no signs in the 2nd group in bar 45).

b. 51

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

in GC (→GE1), EE & GE3

d in FE & GE2

..

The version of FE with is a result of Chopin's proofreading – there are visible traces of correction in print. It cannot be excluded that the version with was originally present also in bars 3 and 11, where Chopin corrected it in [A]. It would be then a case of overlooking one place while proofreading a few analogous bars (quite a frequent phenomenon in Chopin's pieces). Both changes in later GE are revisions – in GE2 this figure was assimilated to analogous bars 3 and 11; GE3 returns to the version of the base text, i.e. GC.

b. 60-62

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

..

In GC and FE, there are no naturals on the 4th quaver in bar 60 (b3 and b), while in analogous situation in bar 62 (b2 and B) relevant signs were added in GC, probably by Chopin. In the remaining sources, these patent inaccuracies were corrected.

b. 61-63

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

..

The cautionary naturals before the last note in the L.H. in bars 61 and 63 (c1 and c) appear in FE, GE and EE3, yet only in FE one can suspect Chopin's proofreading.
