b. 54

composition: WN 17, Polonaise in B♭ major

No slurs in JC

Slurs in FEF

Slur in PE

..

The slurs of EF are most probably an addition by Fontana. In the main text, we give the undoubtedly authentic slur of PE.

No indication in JC

cresc. in EF

poco cresc. in PE

In the main text we give the indication of PE, probably coming from [A].

Dotted semiquavers in JC, GEF & PE

Semiquavers and rests in FEF

..

The rests of FEF were inserted only at the stage of printing instead of extending dots, present in all remaining sources. Therefore, it is certainly an arbitrary change introduced by Fontana in the last moment and not entirely coordinated with the slurs he added before.

b. 55

composition: WN 17, Polonaise in B♭ major

Slur in JC

Slur in EF

Slurs in PE

..

Two slurs visible in PE are probably authentic. Chopin sometimes used this type of notation in, e.g., the Piano Concerto in F minor, Op. 21, 1st mov., bars 218 and 220.

composition: WN 17, Polonaise in B♭ major

..

In PE, five chords were written on the upper staff; we do not include this kind of notation, as it complicates it unnecessarily – the ensuing part of the L.H. is written in the treble clef on the lower staff. In JC, the 1st quaver is not combined with the subsequent ones. In EF, each of the first two quavers is written down separately. Similarly in bar 91.
