b. 108-111

composition: Op. 25 No 5, Etude in E minor

No markings in FC (→GE) & EE

Pedalling in FE

..

The pedalling, present only in FE, could have been added by Chopin in the proofreading of this edition.

issues: Authentic corrections of FE

b. 109

composition: Op. 25 No 5, Etude in E minor

Lombard rhythm in FC (→GE) & EE

Quavers in FE

..

No traces of corrections do not allow to indicate which rhythm is later, while from the stylistic point of view, both versions seem to be equal. In the main text, we give the version of the base source, i.e. FE.
In FC, there is no dot extending the last note in the R.H., which was corrected in GE.

b. 111

composition: Op. 25 No 5, Etude in E minor

c1 in chord in FC (→GE) & EE

No c1 in FE

..

Lack of the cnote in the 2nd chord is most probably an oversight of the engraver of FE.

b. 114-121

composition: Op. 25 No 5, Etude in E minor

Short accents in FC (→GE), FE & EE

Long accents suggested by the editors

..

In the main text, we suggest long accents, due to a possibility of an inaccurate interpretation of [A].

b. 121-122

composition: Op. 25 No 5, Etude in E minor

No slur in FC (→GE) & FE

Slur in EE

..

The slur of EE is probably authentic, which would support the interpretation of the slur in bars 122-123 as beginning from the 2nd crotchet. However, an editorial revision cannot be entirely excluded here (the same applies to the staccato dot under the bass at the beginning of bar 122).
