b. 40

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

..

In GC and FE1 (→FE2FE3FE5) there is no  before the 1st note in the R.H. This patent, from the harmonic point of view, mistake was corrected in GE, EE and FE4 (in the case of the last two editions, Chopin's proofreading cannot be excluded). A natural was added in FES too.

e in GC & GE2

g in GE1 (→GE2mar)

f in FE (→EE)

..

Both the version of GC (introduced later in GE2) and of GE1 (→GE2mar) are most probably a mistake. In the main text, we give the only correct version of FE (→EE).
