Ornaments

b. 19

composition: WN 17, Polonaise in B♭ major

 in JC & EF

No ornament in PE

Our variant suggestion

..

According to us, lack of the ornament in PE is probably a consequence of the engraver's error who did not understand the notation of [A] or simply forgot to include a relevant sign. Therefore, in the main text we propose a possibility of considering a mordent (in this context  = ).

b. 21

composition: WN 17, Polonaise in B♭ major

 in JC & EF

 in PE

..

In the main text we give the ornaments in the form of  included in PE. The remaining sources feature . In this context, both markings translate into the same performance.

b. 23

composition: WN 17, Polonaise in B♭ major

Arpeggio sign in JC & EF

No sign in PE

..

In PE there is no arpeggio before this chord, which in this context is certainly an oversight. In JC, both signs of arpeggio in this bar are placed after chords. It seems to be one of the numerous graphic slips committed by the copyist (it also concerns bar 50, which is not written out in JC).

In each of the sources, the ornament at the end of the bar has a different form. We adopt  written in EF over the R.H., as its application in this place does not raise any stylistic doubts, while  in PE may be a result of a misreading of the sign by the engraver (both  and  tend to be very similar in Chopin's autographs). Therefore, the main text combines the most certain elements of the sources: an ornament, only in the R.H., as it is in EF and PE, and the sign of  from JC and EF.

None of the sources marks lowering the upper note of the trill. We complete this deficiency, as the use of appropriate alterations was most often left to the performers' perspicacity; moreover, the use of a is unquestionable here.

b. 25-31

composition: WN 17, Polonaise in B♭ major

 in JC & EF

 &  in PE

Our alternative suggestion

..

In PE, the notation of the ornaments on the 2nd quaver in bars 25, 27, 29, and 31 is heterogeneous and taking into account coherent indications in JC and EF (four times ) – probably inaccurate. Therefore, for the main text we adopt the notation of JC and EF. As an alternative solution, we propose a possible reconstruction of Chopin's idea in [A]. After all, the difference does not have any impact on the performance.
