b. 10-11

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

..

The crossings-out visible in A reveal an earlier version of the L.H. figures; in that version the 4th note of each of them was like the second and not the first. Analogous corrections are also visible in b. 55 and 70, which may mean that in the working notation of the Prelude, which Chopin used while writing A, the entire L.H. part was based on such figures, and the change to the final version was not marked at all or only signalised, e.g. at the beginning of the piece. The aforementioned corrections would therefore suggest that the composer temporarily lost his focus while modifying the figuration at the time of rewriting.

b. 10-12

composition: Op. 28 No. 22, Prelude in G minor

Slurs in A (→FC)

No slurs in FE (→EE1)

Slurs in GE

Slurs in EE2

..

The missing slur in b. 10-11 and the slur in b. 12 in FE (→EE1) must be oversights of the engraver. The earlier starting point of the slur in b. 10 in GE is probably a result of the notation of FC, in which the beginning of that slur may suggest such an interpretation (Fontana probably took the bottom arm of the accent/diminuendo in A for the beginning of the slur). In EE2 the slurs were added probably after GE (in b. 10 inaccurately).
See also the next note.

b. 10-11

composition: Op. 28 No. 21, Prelude in B♭ major

Slur from semiquaver in A (→FEEE)

Slur from minim in FC (→GE)

..

A late start of the slur is one of numerous slurring inaccuracies of Fontana in this Prelude – cf. the note to b. 2-4.

b. 10-11

composition: Op. 28 No. 15, Prelude in D♭ major

..

In A one can see that the first two quavers in b. 11 were crossed out; they were initially f2-d2. It was also a tie to the former, running from b. 10, that was crossed out. It is probably a correction of an erroneously introduced fragment of b. 14-15.

b. 10

composition: Op. 28 No. 14, Prelude in E♭ minor

..

In A (→FE) a cautionary  is only before c1. In the main text we add a corresponding accidental also in the L.H. That addition was already introduced by FC (→GE) and EE. See also b. 13.
