b. 70

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

b2-d3 in GC (→GE) & FE2 (→EE,FE3FE4)

Open octave in FE1

..

The absence of the middle notes of the chord at the beginning of the bar is certainly an oversight of the engraver of FE1.

b. 70-71

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

Slur from the beginning of bar 71 in GC, FE & GE2

Slur from the end of bar 70 in GE1

Slur from the middle of bar 71 in EE

..

Both the earlier division of the slurs in GE1 and the later beginning of the slur in EE are undoubtedly misreadings of their Stichvorlagen.

b. 71-72

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

Repeated octave in GC (→GE)

Tied octave in FE (→EE)

..

The absence of the ties sustaining the b2-b3 octave is most probably an oversight of the copyist. It is also likely that Chopin added the ties in [A] already after having prepared GC. In any case, the version of FE (→EE) is undoubtedly authentic and must be considered to be the basic one. Cf. analogous bars 199-200.

b. 71-72

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

Continuous slur in GC, FE (→EE) & GE2

New slur in GE1

..

GE1 ends a page on bar 71, and the slur reaches the end of that bar. This may suggest a possible continuation of the slur in the next bar or a tenuto ending of the slur. In bar 72 a new slur starts from the beginning of the bar in support of the latter, and that is how we reproduce it in our system. In any case this amounts to the engraver's inaccuracy, amended in GE2.
