b. 6-8

composition: Op. 25 No 4, Etude in A minor

No signs in A (→FE)

  in FC & EE

  in GE

..

In the main text we give a pair of   hairpins added most probably by Chopin in FC and base text to EE. The shift of the  sign in GE was probably a result of division of the score into great staves – bar 7 falls at the end of the line.

b. 7-15

composition: Op. 25 No 4, Etude in A minor

..

At the beginning of bars 7 and 15 we add cautionary naturals before and g. The signs before the 1st quaver in both bars were introduced in GE and EE3, before the second – only in GE2 (→GE3).

b. 8

composition: Op. 25 No 4, Etude in A minor

 in A (→FE)

No sign in FC (→GE) & EE

Our variant suggestion

..

It is unclear why the  sign visible in A (→FE) was neither in FC (→GE) nor in EE. It could have been Fontana's oversight in FC and a similar inaccuracy in the base text to EE or in the very edition. It is also possible that Chopin added this sign in A already after having prepared the copy. According to us, crescendo, although not necessarily, is not contrary to the previous dynamic nuances, hence in the main text we leave its inclusion at the discretion of the performer.

b. 8

composition: Op. 25 No 4, Etude in A minor

No markings in A (→FE,FCGE)

Pedalling in EE

Our variant suggestion

..

The pedalling in EE can be authentic. However, one cannot totally exclude an editorial revision, which could have introduced here an indication drawn from analogous bar 46.

b. 8

composition: Op. 25 No 4, Etude in A minor

..

In EE there is no  returning f2 (despite the presence of – as in the remaining sources – cautionary  before g2). It is most probably an oversight of the engraver or copyist performing the base text to EE.
