After the  sign in bar 117, the sources do not include a  asterisk. In the main text we suggest adding the sign after similar bar 111.

b. 120

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

B in GC & FE (→EE1)

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).
