b. 8

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

Slur to g1 in As

Slur to a1 in remaining sources

..

The slur of As ends – just like the previous one – on the last note of the four-bar section. The shorter slur of A seems to fit the phrasing better, if we take into account the accented g1 syncopation. Therefore, the idea to break the monotone regularity with an accent on g1 (apart from slurs, it is the only performance indication included in As) could have appeared in the final phase of drafting the Prelude, after the slurs, reflecting that regularity, had already been written down.

composition: Op. 28 No. 6, Prelude in B minor

  in A (→FEEE)

No markings in FC (→GE) & CGS

The lack of   hairpins in FC (→GE) is most probably an oversight by the copyist.

In contrast with A, in FE (→EE) the last L.H. figure was written in the treble clef, thanks to which it was not necessary to repeat the flats next to the 2nd and 3rd semiquavers. However, FE1 misinterpreted the  before f1 as a , which changed that note into f1. The erroneous accidental was removed in FE2 (→EE). We reproduce both that mistake and the changed layout only in the graphical transcription ("transcription").

In A before the 2nd demisemiquaver in the 3rd group, one can see a crossing-out, most probably of a  lowering it to c3. It would confirm that Chopin was convinced that accidentals before the 2nd and 8th demisemiquavers in each group are not necessary, since their pitch is determined by the preceding note, placed an octave lower. Similarly in the Prelude in E no. 19, bar 13 and 39.
