 in JC & EF

 in PE

..

The sources based on the earlier autograph have the ornaments written at the beginning of those bars as , while PE, based on the later autograph – as . In this context, Chopin often used those symbols interchangeably to determine a mordent. Cf. the remark concerning bar 24

b. 15

composition: WN 17, Polonaise in B♭ major

Arpeggio sign in JC & PE

No sign in EF

In this context, lack of the arpeggio in EF must be considered as an inaccuracy of the notation.

b. 16

composition: WN 17, Polonaise in B♭ major

Grace note in JC

No grace note in EF

Grace note in PE, interpretation

..

Lack of the grace note in EF is most probably a result of Fontana's error in preparation of the base text (copy of [AI]). The difference in the grace note's form – non-slashed in JC, slashed in PE – has no practical meaning in this context, as Chopin often did not pay attention to this detail. The sharp before the ornament is a patent error of the engraver of PE.

Slurred grace notes in PE

..

The sources differ in the form of the grace notes (the number of ties, presence of the slur). In the main text we adopt the most complete notation of PE.
