b. 142-144

composition: Op. 38, Ballade in F major

Pedalling in A (→FE,EE)

No markings in GC (→GE)

..

b. 142

composition: Op. 38, Ballade in F major

10-semiquaver slur in A (→FE,EE) & GE

6-semiquaver slur in GC

..

In A (→GC) bar 142 was divided into two lines. It is probably due to this issue that the copyist forgot to continue the slur in the L.H. in the 2nd half of the bar. In GE the slur was extended to the last semiquaver.

b. 142

composition: Op. 38, Ballade in F major

..

A (→GC,FE1FE2) has no  raising c1 to c1 in the L.H. The patent Chopin's oversight was corrected in EE, FE3 and GE.
In A (→GC,FE), in the 2nd half of the bar there is an unnecessarily repeated  before c2. The accidental was necessary in the manuscripts because the line ends in the middle of the bar. It was omitted in EE and GE.

composition: Op. 26 No 2, Polonaise in E♭ minor

Seventh b−a1 in A (→FEEE)

Octave a-a1 in GE

..

As in bar 38, the octave in GE is probably an arbitrary revision of the editor.
