b. 39

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

a in GC (→GE) & FE1 (→FE2FE3,EE)

b in FE4

..

In the main text we give the version of FE4, being probably a result of Chopin's proofreading. Both source versions are equally justified with the voice leading:

  • b in FE4, together with the bottom notes of the adjacent chords of the R.H., creates a d1-c1-b-a line;
  • a in the remaining sources is a common note of four chords preparing the entrance of the second theme in bar 41.

b. 44-48

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

..

In bars 44 and 48 FE1 has no naturals before the 2nd crotchet. A double mistake of the engraver is proved by the flats before the last notes in these bars.

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

FE1 (→FE2) has an e as the bottom note of the 1st minim in the L.H. This patent error was corrected in FE3 (→FE4). The remaining sources also include the correct text.
