b. 28

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

..

Similarly as in bar 20, Chopin's mistake in [A] caused that the correct notation of the trill appeared in the editions – despite the proofreading of FE3 – only in GE2 and EE2. The mistake was corrected in all pupil's copies.

It seems to be highly unlikely that the change introduced in the proofreading of FE3 (→FE4,FE5) would correspond to Chopin's intentions. The present in the remaining sources B-A step of the enforced with octaves bass constitutes here the essence of the transition, introducing the middle section in the D major key. The importance of this step is emphasised by the slur in GC. It is likely that at the time of this correction a kind of misunderstanding arose (cf. the commentary to bar 20 and analog.). In two pupil's copies – one with B (FESch) and one with d (FED) – there are no corrections, yet in FES Chopin changed d to B. See also bar 84.

Quavers in FES

..

The written in FES version with a chromatic, quaver progression of the bass constitutes a diversification of the transition to the D major section, referring to the ending of bar 22, same as the original transition refers to bar 14.

Fingering written into FESch

No teaching fingering

..

The fingering in the L.H. in bars 31 and 34, which may come from Chopin, was written in FESch. Similarly in bars 33, 35-36, 39-40, 43 and 46. Cf. the Nocturne in C minor, Op. 27 No. 1, bars 13-14.
