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.
