b. 8

composition: WN 17, Polonaise in B♭ major

4 notes in JC

4 notes in EF

3 notes in PE

..

The additional note appears in the versions of JC and EF based on an earlier autograph. Its omission in a later version of PE mitigates the impression of parallel shift of chords in combination with the previous bar.

b. 8-10

composition: WN 17, Polonaise in B♭ major

No markings in JC & EF

Dots and slurs in PE

..

Dots under a slur were willingly used by Chopin to indicate the portato articulation (cf. e.g. the Nocturne in D major, Op. 27 No. 2, bar 35, the Mazurka in B minor, Op. 24 No. 4, bar 138). Therefore, we consider this characteristic indication, present only in PE, as most probably authentic and we give it in the main text.

b. 9

composition: WN 17, Polonaise in B♭ major

No indication in JC & PE

 in EF

Our suggestion

..

 marking, appearing only in EF, seems to correspond to the indication tranquillamente present in PE. As in the base source the dynamics of the new phrase is not determined, in the main text we suggest a possibility of considering this indication.

Pedalling in PE

..

In the main text we consider the pedalling of PE, which by all means seems to be authentic.
