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

g2 in GC (→GE) & FE1 (→FE2FE3,EE1)

g2 in FE4 & EE2

..

It is hard to state whether the  added – probably by Chopin – in FE4 was a correction of a mistake or a change of the concept. According to us, the first possibility seems to be more likely.

Slur in GC, literal reading

Arpeggio sign in GC, contextual interpretation

No sign in FE (→EE1)

Tie to grace note in GE & EE2

..

The tie visible in GC before the chord means an arpeggio in this context. The version of GE, repeated then in EE2, is a result of a routine revision – the sign was moved to the side of the note head of the dgrace note, which gave it a form of a tie sustaining the grace note (cf. the note on the part of the L.H.). No slur in FE (→EE1) is most probably an oversight.

FE1 includes an erroneous c1 as the grace note, which was corrected in the next impressions.

b. 169

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

Slur up to f in GC

Slur up to B in FE (→EE)

Slur below notes in GE

..

In the main text we reproduce the little slur running from the grace note in the version of GC, in this case probably closest to [A]. The little slur can be, according to us, interpreted as a conventional sign, by playing the grace note and the fifth, or as a B1-B-f arpeggio. The notation of FE (→EE) is most probably inaccurate (cf. the adjacent note), whereas of GE – routinely revised; at the same time, both eliminate the possibility of a double interpretation.
