b. 275

composition: Op. 39, Scherzo in C♯ minor

..

In FE, the 5th quaver looks like b, as the note head is lacking its ledger line. The intended text is nonetheless obvious here.

No markings in EE

in GC (→GE) and FE

..

In EE, the dashes defining the scope of the diminuendo end as early as bar 274. This is most probably an oversight, as in that edition we find no performance markings (apart from slurs) until bar 286.

b. 275-276

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

in GC

No sign in FE (→EE) & GE

..

The  hairpin was probably added in GC by Chopin. The missing sign in GE is certainly a mistake of the engraver who perhaps was not sure where to put the sign.

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

EE1 has erroneously g instead of a as the inner note of the last L.H. chord. The mistake was corrected in EE2.
