b. 42

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

g in A (→FC,FEEE)

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.

b. 42

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

..

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. 43-46

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

..

A is missing the  lowering a to a in b. 43 and three subsequent ones, marked in the L.H. part as repetition thereof. The patent inaccuracy was corrected both in FC (→GE) and FE (→EE).

b. 47-49

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

..

In A and in the remaining sources there is a cautionary  next to A in b. 47. In the main text we add in this bar a  also next to a. The accidental was also added in FC (→GE). In addition, since in FC (differently than in A) b. 48-49 were marked in an abridged manner as repetition of b. 47, GE printed the cautionary naturals next to A and a (present in FC in b. 47) also in b. 48-49. All those cautionary naturals (including the unnecessary ones) were also introduced in EE2, most probably on the basis of comparison with GE1.

No marking in A (→FCGE, →FEEE)

Long accent in FES, possible interpretation

..

The pencilled addition in FES, big but vague, could be a  mark or – which, according to us, is much more likely – a long accent. The best candidate for an accent seems to be the dotted b1-b2 quaver; however, due to the above interpretation being surrounded by uncertainties, we do not suggest it in the main text.
