b. 82

composition: WN 17, Polonaise in B♭ major

Chord with in JC & EF

Chord without in PE

..

In the main text we give the chord without the note, as it is in PE. Chopin, as was characteristic of him, achieves here a more transparent sound by reducing the number of notes.

b. 86-87

composition: WN 17, Polonaise in B♭ major

..

In JC there is no  returning e on the 2nd crotchet in bar 86; in turn, there are two other unjustified signs – before on the 3rd crotchet and a  before e at the beginning of bar 87. According to us, the latter were mistakenly written two crotchets too far, hence we omit them.
