b. 5

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

 in A (contextual interpretation) & GE

  in FC

  in FE

  in EE

No marking in CGS

..

Just like in the similar situations in b. 1 and 3, we believe that it is the top arm of the  mark in A that is more reliable. In FC Fontana averaged the length of the mark, which is one of possible solutions. We consider the mark in GE, slightly shorter than in FC, to be compliant with our interpretation of A. The mark of FE, stretched out, so that it covers an entire bar (and inaccurately reproduced in EE), is most probably a revision.

The placement of the  mark in CXI is probably an inaccuracy. However, if the manuscript was indeed based on a lost authentic source, such a later pedal, resulting in the notes ringing out clearer further on in the bar, could have come from Chopin.
The oversight of the  mark is probably an inaccuracy of the copyist – there is a similar situation in bar 8.
The missing pedalling indications in CGS – see b. 3-4.
The oversight of the engraver of EE1 was rectified in EE2.

There is not a single tie in CGS (b. 5-6, 8-9, 11, 15-16), which almost certainly results from an oversight.

b. 5-13

composition: Op. 28 No. 8, Prelude in F♯ minor

..

In this Prelude Chopin generally did not use accidentals before the top notes in broken octaves – see b. 1-4. In the discussed bars, the problem concerns the following cases:

  • in b. 5 e2,
  • in b. 7 d3 and d3,
  • in b. 8 c3, c3 and b2,
  • in b. 9 b2, b2, a2, g2 and c3,
  • in b. 10, c3, c3, b2 and a2,
  • in b. 11 c3 and b2,
  • in b. 12 g2, f2 and g2,
  • in b. 13 g2, f2 and c2.

Such a notation is in A (→FC,FE), whereas EE1, EE2, GE1 and GE2 added the majority of the necessary accidentals (17, 20, 21 and 22 out of the necessary 23, respectively).

b. 5

composition: Op. 28 No. 8, Prelude in F♯ minor

..

In A there is no accidental before the 1st note in the 4th group of demisemiquavers, which should therefore be interpreted as a1. A comparison with analogous b. 1 proves Chopin's mistake; it is also the  before the next a2 that confirms a1 as the intended pitch of that note. The natural was added in FC and FE (→EE); however, it is absent in GE, which is probably an oversight of the engraver.
We omit the cautionary  before a2 in the main text.
