b. 32

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

..

The L.H. in GC has a G as the 1st and 7th quavers. In GE the mistakes were corrected, probably on the basis of analogy to similar figures in bars 31 and 33-34.

No accidentals in sources (literal reading—C-c)

Lack of the naturals raising C-c to C-c is almost certainly Chopin's mistake, despite the fact that this kind of oversights of signs introducing alterations are not frequent (yet they are to be found in, e.g., the Etude in F minor, No. 2, bar 56). It could have seemed that the C-c octave did not require naturals due to the following reasons:

  • on a number of occasions, Chopin was not sure whether the last or the following it key signature is valid or not, particularly when their number was significant (cf., e.g., the Etude in G minor, No. 6, t. 7-8).
  • the chromatic progressions are characteristic for the melodic structure of a number of fragments of the Etude, e.g., in bars 1-3, 10, 23-24 (in the latter they are also in the harmonic structure). The last such fragment are bars 32-36;
  • the harmonic progression at the transition between bars 34-35 was probably supposed to refer to the progression in bars 32-33, where there is C-c. Therefore, the psychological mechanism of overlooking the naturals could have been similar to the one that was responsible for omissions of the signs of the current key – here is the signs of the current harmonic context that would have been omitted.

Missing in GC are three augmenting dots for all the three minims in that bar. That obvious omission was corrected in GE.
