b. 67

composition: Op. 45, Prelude in C♯ minor

Rhythm and slur in FE1

FE2 and EE1

Rhythm & slurs in EE2

Additional combination of rhythm and slur

..

The rhythm of FE (→EE) is probably earlier or was even left inadvertently at the time of possible corrections in [A1]. Due to that, we give priority to the version of GE (also introduced into EE2). A similar difference also occurs in bar 71.
In both sources based directly on autographs – FE1 and GE – the slur in that bar continues the slur from bar 66. The remaining versions of slurring are, according to us, not authentic. An additional combination fully enables to independently treat the rhythm and slurring here.

b. 67

composition: Op. 45, Prelude in C♯ minor

..

The slurs in the R.H. have three version in the sources, out of which only one – the continuation of the slur from bar 66 – is authentic, according to us. Due to the need to coordinate the versions of the slurs with the versions of the rhythm in the 1st half of the bar, the slurring variants are considered in the remark concerning rhythm.

Long accent in EE

..

In the intention of the engraver, the accent in EE was probably a short  mark.

Two 's in EE2

Our suggestion

..

Considering the indication crescendo in bars 63-66, various placement of the  mark in FE and GE must be considered as relevant. Not being sure whether the place of the sign in GE really follows the notation of the autograph, in the main text we move  between the stave (it does not change its operating area). In EE2 the indications of FE (→EE1) and GE were compilated.

composition: Op. 45, Prelude in C♯ minor

No hairpin in FE (→EE)

 in GE

Our alternative suggestion

..

In the main text we give the hairpins  of GE. As an alternative, we propose a version which can be considered an attempt to reinterpret the sign.
