b. 224-225

composition: Op. 23, Ballade in G minor

No slur in A

a-d slur in FE (→GE,EE)

c-d slur suggested by the editors

..

It is highly unlikely that the slur added in the stage of proofreading FE (→GE,EE) was supposed to have such a range. According to us, Chopin entered into the proof copy a slur running from the c minim, perhaps inaccurately, which resulted in it starting later in the editions (the slur pointed upwards, just like the one in b. 226-227, which we do not reproduce in our transcriptions). This interpretation is supported by the aforementioned slur in b. 226-227, also added in the stage of proofreading FE.
Such misrepresentations are very frequent in the case of ties, e.g. in the Polonaise in F minor, Op. 44, b. 201-202

b. 224-226

composition: Op. 23, Ballade in G minor

..

In A (→FE), in b. 224 and 226, the accidentals in the R.H. part are present only at the beginning of the quaver figuration – before a2 in b. 224 and a1 and a2 in b. 226. The missing flats to the topmost note in these bars were added by GE and EE.

In A (→FE), Chopin overlooked the sharps raising f3 to f3 in b. 225 and 227. The accidentals were added by EE, while GE repeated both accidentals before these sixths,  and .

In the main text we add a cautionary  to a1 in b. 225. A respective accidental in b. 227 was already added by FE (→GE,EE), most probably at Chopin's request – cf. b. 217-219, in which Chopin wrote this  in A the second time, i.e. in b. 219.

The version of EE is a typical Terzverschreibung mistake, in this case probably additionally influenced by the sixths in the adjacent bars.
