Slurs in A (→FEEE)

No slurs in FC (→GE)

The missing curved lines in FC (→GE) is a serious mistake of Fontana, who also overlooked in these bars the dashes marking the range of stretto and the accents in b. 64-65.

In A certain verbal indications seem to be inaccurately written here: dashes marking the range of cresc. not reaching the  mark, the stretto indication beginning in the middle of the semiquaver septuplet in spite of it concerning the quaver phrase in b. 61-63 or the culminant  mark placed over the R.H. part, although it almost certainly applies to both hands. Taking into account the above, in the main text we suggest a compromise contextual interpretation of the notation of A. The other variants we consider fully legitimate are: the notation of A (interpreted literally), the version of FC (which can be considered an accurate interpretation of A) and the text of GE (with reservations). The inauthentic changes and inaccuracies in FE (→EE) distort Chopin's intention to a certain extent.

b. 60

composition: Op. 28 No. 24, Prelude in D minor

..

The denser notation of A suggests that the demisemiquaver rest and the beam changing the semiquaver to a demisemiquaver were added by Chopin later.

b. 61-63

composition: Op. 28 No. 24, Prelude in D minor

Dashes after stretto in A

No dashes in FC (→GE) & FE (→EE)

..

Chopin carefully marked the range of the stretto indication with dashes – at the beginning of b. 64, one can see another dash in A, crossed-out so that the last three accented octaves were not "squished together" anymore. By an unfortunate trick of chance, the dashes were overlooked both by Fontana in FC (→GE) and the engraver of FE (→EE).
