A significant part of the differences in the notation of the final chords may be attributed to the errors of interpretation of manuscripts and changes and additions performed by the editors. As a result, it is only the notation in A and EE that differ significantly. However, they also give practically the same sound effect, having regard to the authentic pedalling.

b. 126

composition: Op. 38, Ballade in F major

b in A (→FE,EE)

b in GC (→GE)

..

Determining the sound of the third intended by Chopin in the bottom voice of the R.H. is a difficult task. A (→FE,EE) has a b-d1 third with a cautionary  before b. In the same place GC (→GE) has a , written by Chopin's hand, which gives b-d1. According to us, this entry could have been a result of the composer's mistake, who was reviewing GC in a great hurry (cf. bars 202-204) and could have mistaken this bar for bar 124. The factors contributing to such a mistake are the fact of beginning a new page in GC from bar 126 and omitting the cautionary  before b. Due to these facts, in the main text we give the undoubted version of A.

Slur in A (→EE,GCGE)

No slur in FE

..

The lack of slur results certainly from an oversight by the engraver of FE.
