b. 5-6

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

1 staccato mark in A

3 dots in GE1

2 dots in FE (→EE)

4 dots in GE2

..

In GE, staccato dots under the C-c octaves were added together with the slurs. In FE (→EE) the one in bar 5 was overlooked, perhaps deliberately, taking into account the lack of a corresponding sign in the part of the R.H. GE2 completed unification of the notation of the pairs of chords in these bars, which, judging on the notation of A, did not fall within Chopin's intention.

b. 6-7

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

Slur to f2 in A (literal reading→GE1FE)

Slur up to e2 in A, contextual interpretation

Slurs in both hands in EE & GE2

..

The slur of A, although unfinished in bar 7 on a new page, clearly leads to the crotchet at the beginning of the bar, which was not reproduced in the editions. The slur of the L.H., added in EE and GE2, is certainly inauthentic.

b. 8

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

Slur up to f2 in A

Slur to g2 in GE (→FEEE)

..

Admittedly, the slur of A does not reach the very end of the motif, yet it was extended, which proves that Chopin meant a sign embracing all notes in the R.H. in this bar.
