b. 19

composition: Op. 28 No. 4, Prelude in E minor

Slur from crotchet in As & GE

Slur from grace note in remaining sources

..

The slur of As begins more or less in the middle of the bar, so it can be interpreted as starting from the f1 minim. According to us, a slur of such a range concerned the initial version of the ending of the bar; following its deletion, it is only the a1 crotchet that remained, and the slur inevitably begins from it. A slur starting from the a1 crotchet is also included in GE; however, it is a result of a routine revision, adjusting the notation to certain general notation conventions.

b. 20-21

composition: Op. 28 No. 4, Prelude in E minor

..

On the basis of the available photograph of As, it is impossible to interpret the L.H. part in the 1st half of b. 21. Chopin changed the text in the entire bar as well as at the end of b. 20; initially, that fragment most probably looked like that:  (like most similar situations, it is only the 1st chord of each four that includes all noteheads). In b. 20 the top notes of the last two chords were then changed to a, whereas in b. 21 Chopin crossed out the e note in the 1st group and two last quavers in each group; in addition, at the beginning of the bar he added a new 1st half of the bar. On the photograph, the only thing to be seen there is a blot, yet its general outline seems to confirm the natural assumption that it is a very condensed, abridged notation of the final version, i.e. repeated c-g fifth. The text of this half of the bar is highly hypothetical, hence we put it in square brackets.

composition: Op. 28 No. 4, Prelude in E minor

Continuous slur in As, A (→FEEE) & CGS

Separate slurs in FC (→GE)

..

The division of the slur in FC (→GE) could have resulted from a misinterpretation of A – the copyist could have overlooked the fragment of the slur over the dotted fquaver, which blends in with the topmost line of the stave. It is noteworthy that the slurs in As connect almost in the same place as in A.

b. 21

composition: Op. 28 No. 4, Prelude in E minor

..

In A one can see a crossed-out long accent over the e1 minim. According to us, it is likely that the mark was replaced by a  hairpin (cf. the Prelude No. 3 in G Major, b. 17-18).

b. 22-23

composition: Op. 28 No. 4, Prelude in E minor

Dashes up to bar 23 in A

Dashes in bar 22 in FC

No dashes in FE (→EE), GE & CGS

..

The missing dashes marking the range of smorzando is an inaccuracy of FE (→EE) and GE, quite frequent in Chopinesque first editions.
