b. 7-10

composition: Op. 28 No. 3, Prelude in G major

Rhythm & slurs in FCI

Rhythm & slurs in A

Rhythm & slur in bar 7-8 in FC (→GE)

Rhythm & continuous slur in FE (→EE)

..

The rhythm written down in FCI in b. 7 and 9 is most probably the first version. It is evidenced by corrections stemming from that same version, visible in A in b. 9. Therefore, one can conclude that FCI contains an earlier version also in b. 8 and 10 and generally later in the Prelude (b. 16-25).
In FC (→GE) a slur is present only in b. 7-8; the missing one in b. 9-10 is an oversight of the copyist. The four-bar slur of FE (→EE) is also a mistake – the engraver could have been confused by the slur of the crossed-out L.H. part written down on the top stave in b. 8.
There is no arpeggio sign in b. 8 in EE1 – the mistake was corrected in EE2.

b. 7-10

composition: Op. 28 No. 3, Prelude in G major

..

FCI does not contain any accidentals in the R.H. part in these bars. The missing sharps in b. 7 and 9 are a patent inaccuracy (formally speaking, a cautionary  in b. 10 is not indispensable due to the presence of corresponding sharps in the L.H., i.e. raising c1 to c1). Such an incomplete notation was probably present already in the lost autograph that served as the basis for this copy, since it seems unlikely that the copyist would selectively omit marks on the top stave (see also b. 16-17).
There is no  in bar 7 in FC, too – the visible accidental was pencilled in by H. Scholtz, the later owner of FC. The obvious oversight was corrected in GE.

b. 7-9

composition: Op. 28 No. 3, Prelude in G major

Long accents in FCI

No marks in A (→FCGE, →FEEE)

..

FCI contains much more accents – in bars 7 and 9, as well as 12, 16-18, 20 and 22.

No fingering in FCI & A (→FCGE, →FE)

Fingering in EE

..

Nothing indicates that the fingering of EE could be authentic. What is more, a mistake was most probably committed in b. 8 – in the middle of the bar, the b-a notes should be, apparently, played with the fingers 2-1, as they were in the previous bar, in an analogous place. In the copied fingering, it is, however, impossible to reach d at the beginning of the 4th group without crossing the fingers, which should have been marked.

b. 7

composition: Op. 28 No. 3, Prelude in G major

No arpeggio sign in FCI & A (→FE,FCGE)

Arpeggio sign in EE

..

Arpeggio in EE resulted from a mistake of the engraver of EE1, who placed it in b. 7 instead of b. 8.
