b. 267

composition: Op. 21, Concerto in F minor, Mvt I

Slur from c1 in A

Slurs from minims in GE1 (→FEEE)

Slurs from crotchets in GE2

In A the flats were added in this bar in a visible haste, probably to complement the notation after the notes had been written. The signs before C and c are written a third too high, whereas instead of the necessary flats before g and c2 Chopin wrote signs before e and e1. The inaccuracy was not noticed in GE1 (→FE). The necessary signs were added only in EE and GE2, whereas the superfluous flats before e and e1 were removed only in EE

In FE1, the topmost note in this bar is an a1. This patent mistake was corrected in FE2, perhaps by Chopin. It is noteworthy that, in spite of the correction of the pitch, a necessary in this situation flat lowering c2 to cwas not added.

FE (→EE,GE1GE2) is missing the  lowering g1 to g1. Chopin's oversight is proven by the ​​​​​​​ in the respective place of identical bar 265. The accidental was added only just in GE3
