composition: WN 17, Polonaise in B♭ major

No sign in JC & EF

 in PE

No slurs in JC

Slur in EF

Slurs in PE

..

Only in PE the entire part of the L.H. is provided with slurs, which we give in the main text. EF has only the first of them, JC – none of them. Cf. the adjacent note.

b. 20-21

composition: WN 17, Polonaise in B♭ major

Crotchet in JC & EF

Quaver & semiquaver in PE

..

The version of JC and EF is undoubtedly earlier. Not only is the version of PE melodically enriched, but also marked more precisely from the performance point of view (the slur and dynamic hairpins).
