b. 2-4

No marks in A

 signs in FE

Accent &  in GE & EE

Accents suggested by the editors.

..

The  marks, added by Chopin probably in a proofreading of FE (→GE,EE), are certainly meant to be long accents and this is how we give them in the main text. In bar 2 the length of marks in GE and EE corresponds quite well with the size of Chopin's long accents, although most probably by accident.

b. 2-10

composition: Op. 10 No 12, Etude in C minor

Indications in A

No indications in FE (→GE,EE

..

It is uncertain why FE (→GE,EE) does not include the expressive markings written in A in bars 2 and 10. Most probably it is a result of the engraver's inaccuracy (haste?), however, even if it was the case, Chopin did not feel the need to complete these indications at the time of proofreading FE, despite the fact that in bar 2 he added a mark in this place. Therefore, respecting the image of the Etude accepted by Chopin for publication, we do not give them in the main text.

b. 3-4

composition: Op. 10 No 12, Etude in C minor

Slurs in A, literal reading

Slur in FE (→GE,EE

..

We present the literal interpretation of the slurs included in A, however, there is no doubt that Chopin considered this notation to be equal to one slur, as in bars 1-2. A similar hesitation, concerning the choice of space for leading the slur, is visible also in bars 41-42.
In GE2 (→GE3GE4) the end of the slur was moved to the beginning of bar 5, which is a patent error.

No marking in FE (→GE,EE

Our variant suggestion

..

In the main text we suggest a possibility of adding  from A to the dynamic markings of FE (→GE,EE). Lack of any suggestion of emphasising the climax of the chordal motifs in the introduction may be considered here as an inaccuracy of notation.
