b. 120

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

B in GC & FE (→EE1)

in GE & EE2

..

GC and FE (→EE1) do not include an accidental before the bass note, which makes it to be interpreted as a B. The version, present certainly also in [A], is given by us in the main text, with a cautionary . The version of GE, in spite of being most probably a result of a routine editorial revision (until this place the development is maintained in sharp keys and is present also in the next bar), may be, however, considered an alternative authentic version in this case – according to Mikuli, Chopin added a corresponding  in a copy of his pupil, Friederike Müller-Streicher (information from the Mikuli edition of Sonatas, Kistner, Leipzig 1879).

b. 120-121

composition: Op. 64 No 1, Waltz in D♭ major

Chopin's fingering in FED

Chopin's fingering in FES

No teaching fingering

..

In the main text we give the fingering written in FES, most probably indicated by Chopin. The second digit was added in FED too.

EE1 has no  raising g to g. In this context it is a patent error, corrected in EE2.

No ornament in GE (→FEEE)

Our variant suggestion

..

Omission of the  sign in GE1 (→FEEE, →GE2) may be explained by an oversight of the engraver (the sign in A is very small and written carelessly), Chopin's proofreading or its accidental removal while proofreading the slurs, whose traces are most visible in GE1. According to us, the latter is the most likely, yet due to Chopin's potential proofreading, in the main text we suggest a mordent in brackets, which we leave to the discretion of the performer. Cf. bars 109-110.

In A one can see that the last crotchet originally included also e, engraved then by Chopin.
