b. 5-13

composition: Op. 28 No. 20, Prelude in C minor

Slurs to C1-C in A (→FCGE, →FEEE)

Slurs from 1st beat to C1-C & final chord (after AB)

Slurs from 2nd beat to C1-C & final chord in ACh, literal reading

Slurs from 2nd beat to C1-C in ACh, contextual interpretation

No slurs in CGS

..

In the main text we give the unequivocal phrase marks of A and the remaining sources stemming from it. The later autographs – AB and ACh – convey variants that do not seem to be simply inaccuracies of notation. As regards the longer phrase mark of AB – placed in the original in bars 5-9 of the 9-bar version of the Prelude – we admit it to the basic, 13-bar version as a variant of the slur in bars 9-13.
The phrase marks of ACh underline the beginning of the bass passus duriusculus; they also constitute the latest authentic variant concerning phrase marks in these bars. The ending of the phrase mark in b. 9-12 reaches b. 13, which, according to us, is an inaccuracy; however, when interpreted literally, it results in a variant combining both authentic versions of phrase marks.
The missing phrase marks in CGS must be one of numerous defects of that copy.

 in A (→FCGE, →FEEE), AB & ACh

No marking in CGS

As was the case with b. 1, the missing  in CGS is most probably an oversight.

Continuous slur in A (→FC,FEEE), AB, ACh & CGS

Separate slurs in GE

..

The notation of the slurs of FC, although generally compliant with A, may raise doubts – the ending of the slur in b. 5, which closes the line, only slightly goes beyond the bar line; therefore, the fact that the engraver of GE assumed that the slur ended in b. 5 does not actually come as a surprise, especially since the previous three slurs practically reached the bar lines.

b. 5-6

composition: Op. 28 No. 20, Prelude in C minor

..

In FC (→GE), bar 5 is the last in line, and the L.H. slurs in FC do not indicate a continuation. This clearly contradicts not only the notation of A but also the musical common sense. In GE the slur in bar 5 reaches only the last crotchet, in bar 6, however, the traces of the slur having been shifted so as to suggest the continuation from the previous bar. In bars 9-12, based in GE on the script of bars 5-8 in FC (in the copy bars 9-12 are only marked as a repetition of bars 5-8), this edition has a continuous slur, confirming to a certain degree how musically obvious this slurring is. Taking this into account we only reproduce the slurs broken after bar 5 and 9 in the graphical transcription of FC ("transcript" version).

b. 5

composition: Op. 28 No. 19, Prelude in E♭ major

..

The 3rd quaver in GE1 is a c2 (with a ). At this pitch, a natural does not cancel anything; in turn, it deprives the 6th and 9th semiquavers of necessary alterations, which points to a Terzverschreibung mistake, irrespective of the compliant version of the remaining sources. The error was corrected in GE2 (→GE3).
