Issues : Cautionary accidentals

b. 1

composition: Op. 25 No 2, Etude in F minor

..

In AT, AW and CDP, there is no cautionary flat before the 4th crotchet (b). It may mean that Chopin added the sign in [A], at the time of preparing the Etude for print, shortly before giving [A] for copying.

..

Chopin hesitated whether to put cautionary flats before d1 and d3. The signs are included in the earliest source (AT) and in the published version, including GC (→GE), FE and EE. In turn, in CDP there is only the second of them, while AW included the first one (in the L.H.), yet Chopin eventually deleted it. Despite this fact, in the main text we give exactly this , returned in the later sources and, according to us, justified.

Before the 8th semiquaver, CDP, GC (→GE) and EE have a cautionary  (unnecessary in this context). FE has an erroneous  in this place, which was corrected by Chopin in FED and FES.
