b. 12

composition: Op. 28 No. 1, Prelude in C major

..

In GE the middle note of the 2nd triplet is an erroneous d1. It is a consequence of the note having been inaccurately placed – too low – in FC.

b. 12-13

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

..

In As one can see crossings-out in the R.H. part. In b. 12 the tied f1 note was probably a semibreve at first, inserted – in accordance with the Chopinesque practice – more or less in the middle of the bar. Chopin then added a minim stem to the note and a rest later in the bar; eventually, he moved the minim to the beginning of the bar.
B. 13 was initially filled with an a1 semibreve, which Chopin then crossed out; however, he did not insert a rest instead of it.

b. 12

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

..

The notation of As reveals that Chopin initially envisaged c1 as the topmost note already in the 1st half of the bar – the repeat sign, placed after the written-out group of 4 quavers (featuring c1), was crossed out and inserted in front of it; moreover, Chopin added a new bar line before the crossed-out mark (however, the old bar line was not crossed out, as a result of which the space between them creates an impression of an additional bar).

Slur in FCI

No slur in A (→FCGE, →FEEE)

..

In the final version the slur of FCI lost its sense due to the individual elements of the phrase having been separated with rests.
