b. 45

composition: Op. 45, Prelude in C♯ minor

..

In FE1 there is no  in front of the lowest note of the chord in the R.H. (e2), as well as in front of the 6th and 7th quavers in the L.H. (a and e1). The necessary accidentals were added in FE2 and EE. GE also has a correct text.

Rhythmic notation in FE & GE

..

The notation of FE and GE is certainly inaccurate, which was corrected by the reviser of EE. Similarly in bar 38.

No marking in FE (→EE1)

 in GE

Our suggestion

..

Lack of  mark in FE (→EE1) is a patent error, as in bar 48 there is a  mark. In EE2 the notation was completed on the basis of an analogous situation in bars 38-39, however, it does not have to follow the notation of Chopin's autograph. In the main text we give the version of GE, completed with the proposition of a pedal depressed together with the appearance of the bass note of the F major chord, which enables achieving a clear sound of the passage also on contemporary pianos.

b. 47-48

composition: Op. 45, Prelude in C♯ minor

..

The sources differ in the placement of cautionary naturals before the notes in those bars. FE has only one natural and just in bar 48 (before the 3rd quaver). The sign is also present in EE, in which, however, another three were added in bar 47 – before a2 in the chord at the beginning of the bar and two in the L.H. In GE  were placed before the first appearance of the note in each hand; undoubtedly, the sign before the 4th quaver was added during the proofing.

Rhythmic notation in FE1

..

The notation of the upper voice in FE1 –  rhythm with the quaver being moved outside the last quaver of the lower voice – indicates the engraver's error, who placed the notes in accordance with the double dotted rhythm (as in GE), yet he added only one dot and stem to them. The error was revised in FE2 and EE1 by correcting the placement of notes and not their rhythmic values. In EE2 the double dotted rhythm was introduced, without changing the layout of the notes.
