b. 21-22

composition: WN 17, Polonaise in B♭ major

Notation of JC

..

The sources differ in the details of the notation of "harmonic legato". In the previous version, the second semiquavers of the groups are extended to the value of a crotchet, except for the last group in bar 21, in which there is no relevant extension (see also the note related to bar 22). In the later version of PE, all those notes are dotted quavers. One could wonder whether Chopin changed here the performance (the second notes of each group were supposed to slightly overlap the next harmony in the previous version) or he just improved the notation, bearing in mind the same performance from the beginning (therefore, the original notation would be simpler, yet less precise).

In GEF there are no extensions in the 1st group in bar 21, which is a patent error (cf. analogous bar 48, in which the relevant extensions are marked).

Slurs in PE

The slurs in EF are probably Fontana's addition (lack of the slur under the first group of semiquavers is probably his oversight). We give the complete and most probably authentic slurring of PE.

Slurs in PE

The slurs given in the main text come from PE. In JC and EF there are no articulation or motivic slurs, although the meaning of the tie combining (sustaining?) two adjacent bnotes in JC is unclear.
