b. 2-6

composition: Op. 2, Variation IV, primitive version

..

In AsI there are no flats restoring b3 at the end of bars 2 and 6. This is a patent mistake – Chopin wrote 'b' over each of those notes. In A those flats are present, yet the accidentals to the 4th note of the 2nd and 4th R.H. passages, a  (b2) and a  (b2), respectively, are missing. This inaccuracy does not create any doubts concerning the text either.
A similar situation is to be found in bars 18 and 22

Pedalling in A (→GE) & FE2 (→EE)

No markings in FE1

..

In bars 2-3, 12-13 and 16-17, in the main text we include the unanimous pedalling added by Chopin to A (→GE) and added at the stage of proofreading FE2 (→EE). The fact that the markings were added to A most probably after [FC] had already been prepared is proven by their absence in FE1.
