The version of PE, in which the textural and sound scheme of figurations is disrupted, according to us without any visible reason, is most probably erroneous.

composition: WN 17, Polonaise in B♭ major

The natural raising binto bis featured only in JC (cf. the note on other naturals in this bar). It is certainly a result of using different convention regulating the rules of validity of the accidentals taking into consideration the octave sign.

composition: WN 17, Polonaise in B♭ major

..

JC includes naturals (cautionary?) before each b3 and bin this bar (except for those in the main text still before the 1st semiquaver of the 2nd and 3rd groups and before the last semiquaver of the bar).

composition: WN 17, Polonaise in B♭ major

No markings in JC & PE

Pedalling in EF

Lack of indications in JC means that the pedalling of EF, although undoubtedly Chopin-like, is – same as the indications in the previous and following bars – probably an addition by Fontana.
