b. 52

composition: WN 17, Polonaise in B♭ major

No time signature in JC & EF

in PE

..

It is hard to determine whether the time signature marking at the beginning of the Trio visible in PE was actually written out in [A]; however, it is very likely that it is the way a few other Polonaises created before Chopin's definitive departure from Poland were written down.

composition: WN 17, Polonaise in B♭ major

Notation in JC & EF

..

The notation of PE, in which the crotchets on the 2nd beat of bars 52-53 and 60-61 are separated from quavers in lower voices, undoubtedly appeared later than the notation of JC and EF. It is compatible with other changes introduced by Chopin into [A] (in relation to [AI]), e.g., in bar 25 and analog.

Tie & slur in JC

Ties in EF

Suggested supplement to EF ties

Ties in PE, possible interpretation

Slurs in PE, probable interpretation

..

The meaning and number of slurs (ties?) starting from the and d1 crotchets on the 2nd beat of bars 52-53 and 60-61 are ambiguous. Each of two slur-like lines visible in JC may be generally interpreted both as ties and slurs, as we cannot be certain that the copyist read the notation of [AIproperly. Consistent ties in bars 52-53 in EF may be a result of Fontana's interpretation and revision, which is indicated by lack of a similar consistency in bars 60-61. However, assuming that the notation in bars 52-53 is correct, we propose to add the missing ties in bars 60-61. As far as the slur-like lines in the base source (PE) are concerned, if we interpreted them as ties, we would receive different piano grips in analogous figures (bars 52 and 60); according to us, it is an argument for reading them as slurs.

Determining which voice-division Chopin wanted to eventually apply in the chords on the 3rd beat of bars 52-53 and 60-61 encounters difficulties due to differences between particular sources and analogous bars, in this case JC due to its ambiguous notation. At the same time, the notation of JC may reflect the notation of [AIto a certain extent, as this kind of continuous put on the one side of the note heads stems of chords can often be found in Chopin's autographs. The notation of EF is almost certainly a result of Fontana's interpretation of [AI]. The version of PE, with its inconsistency, suggests similar difficulties in reading [A].

In this situation, apart from thoroughly recreated versions of EF and PE, we propose the most possible interpretation of JC and two interpretations of PE, going to the other direction.

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.
