b. 56

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

..

FE1 (→FE2) has a b-e1 minim here. The mistake resulted from an erroneous assignment of these notes to the bottom stave, where the bass clef is in force – the mistake's mechanism is easy to understand, looking at the notation of GC (most probably very similar to the notation of [A]). The mistake was corrected in FE3 (→FE4) and EE, mostly likely as a result of Chopin's intervention. GC (→GE) includes the correct text.

composition: Op. 25 No 4, Etude in A minor

No markings in A

Pedalling in FC (→GE), FE & EE

..

The pedalling of FE, generally consistent with the indications written by Chopin in FC and base text to EE, was added by him at the time of proofreading. We discuss minor differences in the indications separately – cf. bars 5859 and 61.
