b. 7

No sign in A1

The L.H. slur, which starts at the beginning of the Prelude, clearly reaches the 1st quaver in b. 8 in A. Nevertheless, both FC (→GE) and FE (→EE) considered it an inaccuracy and led the slur only to the last quaver in b. 7.

b. 7

composition: Op. 28 No. 2, Prelude in A minor

In the main text we add a cautionary  before e on the 2nd quaver. The accidental is written in pencil also in FC; however, it is an addition of Hermann Scholtz, a later owner of the manuscript. In GE, which also includes that , one can see that it was added at the time of proofreading the print version, since there was no place for it at the stage of laying out the text. Therefore, it is an editorial revision.

Rhythm & slurs in FCI

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.
