Verbal indications

b. 1

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

funèbre in GC (→GE), FE1 (→FE2EE) & FE5

No designation in FE3 (→FE4)

..

The fact of removing the programme indication of Marche's character in the proofreading of FE3 (→FE4) can be certainly ascribed to Chopin. The composer replaced it with a neutral tempo indication, Lento. The original indication funèbre was restored, for understandable reasons, in FE5 – the edition was prepared shortly after Chopin's funeral.

b. 1

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

No indication in GC (→GE) & FE1 (→FE2EE1)

Lento in FE3 (→FE4,FE5) & EE2

..

The indication Lento was added by Chopin in the proofreading of FE3 (→FE4,FE5), as if instead the simultaneously removed funèbre. It was repeated – most probably on the basis of FE4 – also in EE2.

b. 21

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

 before 2nd beat in the sources

 at the beginning of bar suggested by the editors

..

There is no doubt that the placement of the  sign in the sources is incompatible with the notation of [A]. However, it does not have to mean that the dynamics is valid only from the 2nd beat of the bar, as Chopin would sometimes use an older convention of placing performance indications not at the beginning, but in the middle of the scope of its validity. According to us, such an interpretation is more likely here than a literal interpretation. Similarly in bars 29, 75 and 83, which in [A] (→GC) were marked as a repetition of bar 21.

b. 31

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

No indication in Amar

in GC (→GE) & FE (→EE)

..

The absence of  in Amar is probably related to a slightly different character of this phrase, when it constitutes a separate whole.
