b. 33

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

 in A (→FE,FCGE)

No sign in EE

..

The missing  sign is most probably an oversight of the engraver of EE or of the person writing the base text for this edition.

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

Wedges in A (→FCGE) & EE

No marks in FE

..

In FE there are no staccato signs in these bars. It is certainly an oversight of the engraver.

In A (→FC,FE) there is no  lowering e to e. This patent inaccuracy was corrected in GE and EE.

GE2 (→GE3) added cautionary naturals before b2 in bar 33, e2 in bar 34 and e1 in bar 35. We give the last two – as justified, according to us – in the main text.

The sources quite clearly differ in the range of   hairpins, which suggests that they were not copied, but introduced by Chopin himself into three Stichvorlage manuscripts. To the main text we adopt the version of FC, as it is more compatible with the indications of EE – both define the dynamic wave filling four bars, which implies that Chopin wrote such a concept twice. The three-bar version of A must be, however, considered as an equal, alternative concept. The reason for omitting the hairpins in FE is unknown; the engraver's oversight seems to be the most likely answer.

We preserve the position of the signs over the part of the R.H., in accordance with the manuscripts. However, one cannot exclude that the reason for such placement could have simply been lack of space between the staves and moving them to the typical place, as it was performed in GE, is justified.
