b. 3

The crossings-out and additions visible in A reveal that Chopin initially provided each of the half-bar figures – in the right and left hands – with a separate slur.

Ties in A (→FC,FEEE) & GE2 (→GE3)

No ties in GE1

..

The missing ties of c1 and e1 are one of a few mistakes of the engraver of GE1 in this place – see adjacent notes. All were corrected in GE2 (→GE3).

a in GE1

b. 3

composition: Op. 28 No. 21, Prelude in B♭ major

..

In A one can see a crossing-out between the  and the 3rd quaver. It was most probably the  before a that was removed (superfluous), yet it seems that, for some reason, Chopin also crossed out the correctly written f-a third, which he then reintroduced next to it. If it was so, the reason could have been, e.g. accidentally blurred noteheads, even partially, as a side effect of removing the natural.
