b. 2-6

composition: Op. 28 No. 23, Prelude in F major

..

Thanks to the crossings-out and added notes in b. 2 and 6 visible in A, we can reconstruct the initial version of the last beat of these bars as  and . The idea of changing it probably arose when Chopin was writing b. 6; afterwards, he introduced a respective correction in b. 2. It is proven by the notation of an analogous figure in b. 10, in which the final version was written right away, without corrections.

b. 3-7

composition: Op. 28 No. 23, Prelude in F major

No fingering in A (→FE,FCGE)

Fingering in EE

..

The fingering of EE in b. 3 does not come from Chopin; however, as is the case with a few other places, it may comply with the composer's fingering. An identical fingering was given in an analogous figure in b. 7.

b. 3

composition: Op. 28 No. 23, Prelude in F major

..

The crossings-out and additions visible in A reveal that Chopin initially provided each of the half-bar figures – in the right and left hands – with a separate slur.

b. 4-5

composition: Op. 28 No. 23, Prelude in F major

Separate slurs in A (→FEEE)

Continuous slur in FC (→GE)

..

In FC the line ends in b. 4, and the slurs, both at the end of b. 4 and at the beginning of b. 5, indicate that the slur should be continued. In A the slurs between the lines also suggest a continuous slur; however, in the case of A the line ends earlier, already in the middle of b. 4. This was most probably the reason for the copyist's confusion: he did not pay attention to the difference in the layout while writing the slurs.
