b. 68

composition: Op. 45, Prelude in C♯ minor

Notation in FE (→EE)

..

In the main text we give the notation of GE, which is more coherent with the notation of appropriate octaves in bar 70 and 74. The version of FE (→EE) most probably means that in that one place Chopin already in [A1] used the notation, which he subsequently, writing [A2] (→GE), considered the better one.

b. 70-74

composition: Op. 45, Prelude in C♯ minor

Rhythmic notation in FE

Our suggestion

..

In the main text we make the notation of the 2nd half of bar 70 and 74 more precise, following the undoubtedly correct and precise notation of FE1 in bar 8 and GE in bar 22.

b. 70-74

composition: Op. 45, Prelude in C♯ minor

 in FE1 (→EE)

Our variant suggestion

..

The  mark appears in the sources in different places between the last quaver in bar 70 and the first one in bar 71 (and similarly in bars 74-75). Those differences may derive from the not entirely precise notation of handwritten base texts of first editions, as in Chopin's autographs the notation of pedalling is sometimes ambiguous. For each of the sources we give the most probable interpretation of that detail.
In the main text, similarly as in analogous bars 8-9 and 12-13, we propose a variant solution in each and every situation.

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.

b. 71

composition: Op. 45, Prelude in C♯ minor

Rhythm in FE (→EE1)

GE and EE2

..

In the main text we adopt the probably later rhythm of GE and EE2.
