b. 18-19

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

..

In FCI the slur reaches only the beginning of b. 18, which in this context is practically tantamount to the longer slur featured in the remaining sources.

b. 21-25

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

..

In b. 21 and 23-25 one can see crossings-out and corrections in A, which prove that Chopin committed mistakes at the time of writing similar bars of the L.H. figuration:

  • Chopin wrote b as the 8th note in b. 21, which he right away corrected to a;
  • the range of a similar mistake in b. 23 was already bigger – starting from the 8th note, Chopin wrote the version of b. 24 until at least the 12th note;
  • in b. 24 the last note was initially written as G (version of the previous bar);
  • in b. 25 the entire 1st half of the bar was written in the version of b. 24, which forced Chopin to cross out the 3rd note in the bar, add a new 4th note and to correct the pitch of 3 notes in the 2nd group of semiquavers.

b. 22

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

in FCI

f in A (→FCGE, →FEEE)

..

The version of FCI, in which the subdominant nature of the C major chord is signalized – by the f note in the L.H. figuration, pointing to the key of G major – only just in b. 23, is most probably earlier.

Semibreve a in FCI

Crotchet in A (→FCGE, →FEEE)

..

The a note cannot be held throughout the entire bar due to the L.H. part. The fact that it was not included in FCI undoubtedly proves that the notation of this manuscript was less detailed and most probably earlier.
