b. 249

composition: Op. 31, Scherzo in B♭ minor

Staccato dots in A (→FCGE)

No marks in FE (→EE)

..

The missing dots at the beginning of the bar (in both hands) is almost certainly an oversight of the engraver of FE (→EE).

b. 249-250

composition: Op. 31, Scherzo in B♭ minor

Slur to f in A

No slur in FC

Slur to d1 in FE (→EE) & GE

..

When interpreted literally, the slur of A encompasses only the quavers. A comparison with the analogous figures proves Chopin's inaccuracy, corrected already in FE (→EE). The missing slur in FC must be an oversight of the copyist, corrected already in GE1 (→GE2GE3).

b. 249-250

composition: Op. 22, Polonaise

..

In the main text we omit the reminder flats before a1 in the last chord of each of these bars.

b. 250

composition: Op. 39, Scherzo in C♯ minor

Pedalling in EE & GC (→GE)

No markings in FE

..

Absence of the pedal mark in this bar in FE is definitely accidental – not only are such marks present in the other sources, but also FE itself has them in analogous bars 258 and 266.

b. 250

composition: Op. 39, Scherzo in C♯ minor

No sign in EE

Arpeggio in GC (→GE) & FE

..

Absence of the arpeggio mark in EE is probably an error, yet the possibility that it is the first (original) notation cannot be entirely ruled out.
