b. 165

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

..

FE (→EE) has a cautionary  before g2 in the 5th crotchet of the bar. It is hard to state how the difference between GC and FE occurred – the copyist might have simply overlooked this sign or realised that it is superfluous. Moreover, one cannot exclude an addition made to [A] after GC had already been prepared or a mistake of the engraver of FE

b. 165-168

composition: Op. 21, Concerto in F minor, Mvt I

The version of FE (→EE), fully analogous with the corresponding fragment of the recapitulation (bars 315-318), was introduced by Chopin in the proofreading of FE1. Both versions are, according to us, musically equal, yet showing respect for Chopin's decision, in the main text we give the later, proofread version. The reason for the change could have been pianistic convenience – following the proofreading, the number of differences between the subsequent appearances of similar two-bar phrases in bars 165-166, 167-168, 315-316 and 317-318 was significantly reduced.

Slurs from 2nd quaver in A & GE2

Slurs from 1st quaver in GE1 (→FEEE)

..

In GE1 (→FEEE), the fact of beginning all slurs over the half-bar figures of the accompaniment in bars 165-166 and 168 from the 1st quaver is a typical arbitrary action of the engraver of GE1. GE2 restored the notation of A. We discuss the atypical situation in bar 167 separately.
