b. 9

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

c1-c2 in GC, FE & Afin

c1-c2 with  in EE

c1-c2 in GE

..

In [A] (→GC,FE), there are no accidentals before the 7th quaver. The logic of the structure of the figuration in bars 9-12 proves that the literal interpretation as c1-cis correct. The undoubtedly justified cautionary naturals were added in EE, which, probably, is, however, a revision. The version of GE with c1-c2, contrary to the remaining sources, indicates a routine approach of the reviser to the Breitkopf & Härtel edition. He introduced the same addition also in bar 46+1, being a repetition of bar 9.

The version of Afin, with a written cautionary  before e1, is certainly authentic, however, according to us, it can be considered to be an equal variant with respect to the published version. Afin was performed with a visible haste, without taking care of the accuracy of notation, whereas its fragmentary character excludes its use as a score to perform the music written in it.

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

..

In GC (→GE) and FE1 (→FE2EE1) there are no naturals raising the 10th quaver to d1(2), which in this context is a patent oversight. The sign in the R.H. was added in the proofreading of FE3 (→FE4,FE5), whereas in FE5 was added also in the L.H. A natural in the part of the R.H. is also in Afin, in which, due to the abbreviated way of notation of the L.H., it refers to both hands.

The  sign was added in GC probably by Chopin. GE extended it, so it filled both bars, in this version it was added also in EE2.
