Rhythm

b. 22

composition: WN 17, Polonaise in B♭ major

Crotchet e1 in JC & EF

e1 not prolonged in PE

..

In the main text we give the notation of PE, yet it seems to be very likely that the lack of extension of the bass note e1 is a consequence of inattention.

In the main text we give the evident, faultlessly written rhythm of PE (together with the slur combining the final with the chord in the next bar). The version of JC includes an error (7 quavers in a bar), however, it is not said that it must have been in [AI]. If this was the case, it has to be the rhythm of EF that would correspond to Chopin's intentions. However, if the rhythmic error had already been in [AI], the version of EF would have been only one of the attempts to guess Chopin's intentions. Therefore, the intended version of [AI] could be generally compatible with the text of PE – one should only correct the erroneous notation by adding a quaver flag to the last (by the way, it would correspond to subscribing the note under the part of the R.H. in JC).

Dotted crotchet in JC

Crotchet in EF & PE

The rhythm in JC is probably original. The version with the rest, included in EF and PE, appears in Chopin's polonaises in this type of cadenza formulas much more frequently.

JC (interpretation) & EF

Our suggestion

..

In bars 25 and 27, the part of the L.H. in the sources is generally the same, as far as the sound is concerned, yet the way of its notation is different in each of them. In the main text we adopt the notation based on PE. At the same time, we propose to complete the tie sustaining f, most probably overseen in PE in bars 25-26. Such an error is suggested by the comparison with both analogous bars 27-28 and 29-30 in this edition and by the hold of the note in JC and EF.

b. 25

composition: WN 17, Polonaise in B♭ major

Rhythm in JC & EF

Rhythm in PE

..

The dotted rhythm at the beginning of the 3rd beat of the bar in JC and EF is most probably an earlier version in relation to equal semiquavers of PE, which we give in the main text.
