b. 29

In bars 29 and 31 we add a cautionary  before a1. In the latter, the sign is in JC.

composition: WN 17, Polonaise in B♭ major

Quaver in JC & PE

Crotchet in EF

..

In JC and PE, the entire 1st chord of the bar is written as a quaver (on one stem). The comparison of the notation with the one of analogous bars 26 and 28 leads to an argument confirming the correctness of the double-voice notation of EF, which we give in the main text.

Even quavers in JC and EF are almost certainly the original version of the rhythm in this place.

b. 31

composition: WN 17, Polonaise in B♭ major

Quaver in JC & EF

Crotchet in PE

..

In the main text we consider the longer crotchet resounding of the bass note, indicated only in PE, as compatible with the performance manner of similar figures in bars 25, 27, and 29.
