b. 168

composition: Op. 35, Sonata in B♭ minor, Mvt II

..

In GC the bar is written in an abbreviated manner as repetition of the previous one. At the same time, one can see that initially the bar was completely overlooked, whereas a relevant abbreviation was written as an addition. It cannot be excluded that the mistake (or unclear notation) was also in [A]. If so, Chopin had to write a respective addition also there, as FE contains the correct number of bars.

Slurs in GC

Slurs in GE

According to us, the slurs of FE (→EE), more consistent, probably convey Chopin's notation in [A] more accurately than the slurs in GC. The latter are imprecise, so it is not obvious how they are meant to be understood, e.g., we interpret the beginning of the slur in bar 177 – differently than GE – as falling on the 2nd beat of the bar. It cannot be excluded that the slur beginning in bar 179 is supposed to be interpreted similarly.
