b. 123-124

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

Probable interpretation of slur in FC

Slurs in FE (contextual interpretation) & GE2 (→GE3)

Grace-note slur in EE & GE1

..

Interpretation of the slurs of the L.H. in FC poses a significant challenge due to the  sign written over the slurs. According to us, it is more likely that the slurs are supposed to create one sign. The slurs of FE and GE2 (→GE3) can be considered an alternative interpretation of the notation of FC. The version of GE1 is certainly erroneous; the one of EE probably too.

b. 130-133

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

Long accents in FC

R.H. long accent in FE

R.H. long accents in EE & GE1

Short accents in both hands in GE2 (→GE3)

..

The long accent in bar 130 must have been included in [A], whereas the remaining were added by Chopin in FC and probably in the base text to EE. The added signs have a form of long accents and this is how they were recreated in EE and GE1. In later GE, they were changed to common, short accents. The signs in FC are placed more or less between the staves and they probably concern both hands. In FE, EE and GE1 they were placed under the R.H., whereas in GE2 (→GE3), another set of accents for the L.H. was added.

b. 138

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

in FC (→GE) & FE

in EE

..

The corrections visible in FC in this and the previous bar – shift of  from bar 137 to bar 138 and addition of con forza – prove a possible addition of indications in all three Stichvorlage manuscripts by Chopin.  in EE can be authentic, although a possibility of a kind of mistake cannot be entirely excluded.
