Rhythm

b. 79

composition: WN 17, Polonaise in B♭ major

Dotted semiquaver in JC & EF

Semiquaver & rest in PE

..

The compatible versions of the rhythm in JC and EF are certainly earlier. The rest visible in PE after the first note of the bar and the slur embracing its subsequent part point to the crystallisation of Chopin's articulation and phrasing concepts in [A] in bars 78-79.

b. 82

composition: WN 17, Polonaise in B♭ major

Rhythm in JC & EF

Rhythm in PE

..

Both forms of the rhythm are undoubtedly authentic and both are justified by certain stylistic arguments. In the main text we give the probably later version of PE.

b. 84

composition: WN 17, Polonaise in B♭ major

Rhythm in JC & PE

..

The compatible rhythm's version of JC and PE (in spite of omitting the dot extending the B quaver in PE) gives reasons to doubt the authenticity of the version of EF.

b. 86

composition: WN 17, Polonaise in B♭ major

Rhythmic notation in JC & EF

..

In the main text we give the notation of PE, as from the formal point of view it is error-free and may correspond to the notation of [A]. The notation of JC and EF, however, seems to be more logical:

  • from the practical point of view – the note cannot be held with fingers as a crotchet, as it was written in PE, due to the fact that it is struck again on the 2nd quaver;
  • due to the voice-lead – in the notation of PE, the progression of the lower voice of the R.H., absolutely regular from the beginning of that phrase in bar 82, is clearly disrupted on the 1st quaver in bar 86.
