Ornaments

b. 9

composition: Op. 45, Prelude in C♯ minor

No ornaments in FE (→EE)

Ornaments in GE

..

The ornament-free version of FE (→EE) is probably earlier, although errors in the reading of [A1] cannot be ruled out completely (they may have resulted from e.g. corrections or deletions in the manuscript). As our main text we give the grace note with the arpeggio, on the basis of GE.

b. 13

composition: Op. 45, Prelude in C♯ minor

No arpeggio in FE (→EE) & GE

Suggested supplement

..

We  propose that the arpeggio mark be added here, in line with the notation used in GE in the analogous bar 9. Arpeggio with the doubled lower note is very characteristic of Chopin, and he often omitted the arpeggio marks for broader chords. Therefore, it is very probable that - having marked the arpeggio upon its first appearance - Chopin considered it obvious in analogous places.

b. 23

composition: Op. 45, Prelude in C♯ minor

Grace note in FE, GE & EE2

Our suggestion

..

The grace note in the form of a small crotchet is certainly an error of EE1, corrected in EE2.
We propose adding an arpeggio mark similar to the notation used in GE in the analogous bar 9.

b. 51

composition: Op. 45, Prelude in C♯ minor

Arpeggio in FE (→EE)

No marking in GE

Our variant suggestion

..

It is hard to determine the reason of this difference. The lack of arpeggio in GE may be a result of the engraver's oversight or the very Chopin's in [A2]. The intentional omission of the arpeggio seems to be the least plausible possibility.

b. 71

composition: Op. 45, Prelude in C♯ minor

Grace note in FE (→EE) & GE

Our suggestion

..

We propose to complete the arpeggio mark on the basis of the notation used in GE in analogous bar 9.
