The notation of the chord on the 2nd quaver in the bar is ambiguous in FC – the c1 note, although most probably written by Fontana, is actually imperceptible and was not included in GE.

The high position of the L.H. chords and the resulting lack of space between the staves contributed to inaccuracies and mistakes in the reproduction of the  hairpin – it was moved in FC (→GE, inaccurately) and overlooked in FE (→EE1). The mark in EE2 was added on the basis of GE1, overlooking its ending at the beginning of b. 18. In GE, there is a complete  mark at the end of the line (in b. 17), in spite of the fact that b. 18 contains its ending in the form of a new  mark – in times of Chopin, the contemporary, more accurate notation of such divided hairpins was not generally used yet. The absence of the mark in CGS is one of the arguments supporting the fact that the copy was prepared on the basis of FE.

b. 17

composition: Op. 28 No. 4, Prelude in E minor

No slur in As & CGS

Slur from 2nd quaver in A (→FC,FEEE)

Slur from 1st quaver in GE

..

The slur in A, written still before the topmost notes of the chords on the 2nd, 3rd and 4th quavers had been added, clearly starts from the 2nd quaver. In FC, although the copyist almost certainly wanted to accurately reproduce the notation of A, the beginning of the slur falls almost over the 1st quaver, which confused the engraver of GE. The missing slur in CGS is an oversight of the copyist, as was the case with the previous slur in b. 13-16.

Separate slurs in FC (→GE)

..

The version of FC (→GE) resulted from a mistake or imprecision of the notation of FC, in which b. 17 closes the line, and the phrase mark barely goes beyond the d2 semiquaver.

b. 17-19

composition: Op. 28 No. 13, Prelude in F♯ major

..

The e1 semibreves in b. 17 and 19 fill entire bars in A – they are dotted and, in accordance with the Chopinesque habit, placed close to the middle of the bar (cf., e.g. the Prelude No. 15 in D Major, b. 84-85). In FC (→GE) the latter is not provided with a dot, while in GE – both are not. It is Fontana's oversight and a standardizing revision or another oversight in GE.
