b. 36

composition: WN 17, Polonaise in B♭ major

..

The sources differ here in the notation of the rest for the part of the R.H.; JC has a crotchet rest, which certainly corresponds to the notation of [AI]. In PE, the crotchet rest is additionally extended with a dot, which is a patent error, however, it reveals that also in the case of [A], Chopin insisted on his simplified way of notation. Two quaver rests in EF are probably a result of Fontana's revision.

b. 37

composition: WN 17, Polonaise in B♭ major

..

In [A] (→PE), bar 37 is the last one written out in notes in this part of the Polonaise. The respective markings (Dal Segno, written as D.S., with a mistake) refer subsequently to bar 11. In the main text we write repeated bars 11-24 as bars 38-51.
In JC, a similar abbreviation of notation includes only bars 40-51. In EF, all subsequent fragments of the Polonaise are written out entirely.

The abbreviations applied in the sources mean that the differences and problems appearing in the bars embraced by them are to a large extent a repetition of those described above. If there are no additional new elements, we do not repeat the content of the remarks, referring to the commentaries given for the first time.

f-d1 in FEF (without tie)

Our alternative suggestion

In the previous sources, the accompaniment generally does not show any difference in comparison with the one in analogous bar 10 (in EF the sustained minims from the previous bar are marked inaccurately ​– a respective tie is featured only in FEF in bars 36(r)-37(r), in Da Capo written out in notes). PE, in turn, has b as the bass note instead of the previous version with the minim (sustained from the previous bar). According to us, it is not certain whether the version was really intended by Chopin: he could have mistakenly written here the original version of bar 38 (=11).

Chord in JC

Chord in EF

Third in PE

Our suggestion

..

Both JC and EF have the f-a-echord on the 3rd beat of the bar, yet they differ in the rhythmic values – in JC all components of the chord have values of quavers, while the upper e1 in EF is a crotchet. In PE, we see a simplified notation of the version of analogous bar 10 (the a-c1 third). According to us, it is probably a result of Chopin's negligence, who while writing [A] was already conscious of repeating the text written before (cf. another note in this bar).

..

In JC, both a1 in the group of semiquavers in the R.H. and in the chord in the L.H. on the 3rd beat of the bar are provided with naturals. It illustrates Chopin's inclination to emphasise the 7th step of the major scale with cautionary accidentals, despite a correct key signature.
