b. 56-57

composition: WN 17, Polonaise in B♭ major

Markings in JC

Our suggestion

..

The articulation – slurs and staccato signs – is marked differently in each of the sources. The markings of JC and EF are incomplete and – despite the fact that they are based (directly or indirectly) on the same autograph – incompatible, which questions their reliability. In the main text we give the markings featured in PE, shortening only the slur in bar 57 (93), which was probably misinterpreted by the engraver.

b. 58

composition: WN 17, Polonaise in B♭ major

No slurs in JC

Slurs in EF

Slurs in PE

..

The general compatibility of slurring in EF and PE – such a type of minor doubt concerning the starting point of a slur is rather a rule than exception in reading Chopin's autographs – allows to assume that they could be in [AI] (overseen in JC or added after its preparation).
