b. 41-42

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

    in A (→FEEE) & contextual interpretation of FC 

   in GE

..

Fontana omitted the  mark at the beginning of b. 41 in FC, leaving a lonely  asterisk at the end of b. 42. GE completed the pedalling; however, in the face of varied L.H. figures in these bars, a separate pedal was added in each of them. The crossing-out of the  mark at the end of b. 41, visible in A, proves that Chopin consciously combined them with pedal. Crossings-out of those marks in similar situations are also present at the end of b. 9, 20 and 54.

b. 42

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

..

In FE the 2nd semiquaver in both figures is an erroneous c note, whereas in EE – most probably as a result of revision of this clearly false version – e. The version of EE, although possible in terms of harmony, is pianistically improbable. In turn, the pencilled correction of c to A written in FES, compliant with the version of A (→FCGE), may come from Chopin.

e in GE, contextual interpretation

..

In GE the 3rd semiquaver in the 2nd half of the bar is an e note, which is a patent mistake in itself; however, if we take into account a possibly overlooked , it constitutes a harmonically plausible version in which we could even see subtlety, so typical of Chopin, since the g seventh is exposed in the R.H. part. Nevertheless, nothing suggests that Chopin could have participated in the development of GE, hence the authenticity of this version cannot be confirmed.

In A (→FC) there are no flats lowering a1 to a1 and a to a in the R.H. The patent inaccuracy was corrected in FE (→EE) and GE.

b. 43-58

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

..

In each of b. 44-46, 49, 52, 56 and 58, the L.H. part is marked with a / in A (→FC), which implies that the preceding bar should be repeated. Moreover, in FC the copyist, contrary to A, marked entire b. 48 in such a way. The abridged notation was used in the manuscripts also in the remaining bars to mark the 2nd half of the bar – b. 43, 47, 48 (only A), 50, 51, 53-55 and 57. Similar notation was also used in FE, where the 2nd half of the bar was marked with a / in b. 43-54 and 57-58.
