& long accent in FE (→GE)

& short accent in EE

2 long accents – our alternative suggestion

..

The differing dynamic markings appearing in identical motifs – in bar 156 and a long accent in bar 157 – suggest that the notation is inaccurate. It is supported by a comparison with analogous or identical bars 152-153 and 164-165, which contain accents. However, taking into account frequent misunderstandings in the reproduction of long accents, we consider it to be likely that it was long accents that Chopin meant in both bars.

b. 156-157

composition: Op. 38, Ballade in F major

Slur in A (→FE)

No slur in GC (→GE) & EE

..

The lack of slur under the bass progression results most likely from an oversight of the copyist in GC (→GE) and the engraver of EE.

FE (→GE1) are lacking in the naturals before the a1 and ademisemiquavers. The latter was added in EE, whereas both – in GE2 (→GE3).
