b. 205

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

b1 in chord in GC (→GE) & FE2 (→EE,FE3FE4)

Octave without b1 in FE1

..

No b1 in the chord is most probably a result of an oversight of the note by the engraver of FE1. The mistake was corrected already in FE2.

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

Chord with f in GC (→GE) & FE1 (→FE2)

Chord without in FE1 (→FE2) & EE

..

The version with f, present in GC (→GE) and the first impressions of FE, is the original version. Chopin removed in the proofreading of FE3 (→FE4) and in the base text to EE.

b. 207

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

No accidental in the sources (g1)

g1 specified by the editors

g1 as our alternative suggestion

..

The version written in the sources, in which the absence of cancellation of the  lowering g1 to g1 imposes to interpret the melodic sound in the last chord as a g1, must be considered to be potentially intended by Chopin. However, a possible oversight of a  is highly likely, as this kind of oversights belongs to the most common inaccuracies of Chopin's notation, whereas a diminished four-note chord – to his favourite chords.

FE1 (→FE2FE3) lacks in a  before the bottom most E1. Chopin corrected his oversight in GC (→GE), EE and FE4 also include the correct version.
In the proofreading of FE4, a cautionary  before e1 in the R.H. was also added. A similar addition was introduced in EE2.

FE1 (→FE2FE3) features an Aas the bottom note on the 2nd crotchet in the bar. This patent inaccuracy was corrected only in FE4. The remaining sources include the correct F1.
