Slurs

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.

b. 8-9

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

Slur up to bar 9 in A

Slur only in bar 8 in GE (→FEEE)

..

While the slur of A ends in bar 9, it is not obvious whether it is actually supposed to reach the quaver. Therefore, the interpretation of GE (→FEEE) is equally justified.

b. 10

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

Slur up to quaver in A & EE

Slur to semiquaver in GE (→FE)

..

The fact of shortening the slur in GE (→FE) is a typical example of an inaccuracy resulting from a routine, "string" approach to slurring. The extension of the slur in EE was presumably performed by analogy with bar 12.

b. 12

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

No slur in A & GE2

Half-bar slur in GE1 (→FEEE)

Our alternative suggestion

..

The slur could have been added by Chopin in the proofreading of GE1 (→FEEE), however, even if it was so, it is hard to assume that he wanted to embrace with it only a part of the bass's motif. In the face of doubts concerning the authenticity of both the slur as such and its range, in the main text we do not include this sign. In turn, we suggest a slur embracing the entire sequence of bass in this bar as an acceptable variant. See also the note on  the hairpin.

b. 12-13

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

Slur in A

Slurs in GE1 (→FEEE)

Slur in GE2

Our alternative suggestion

..

The slur written in A stayed in GE (→FEEE) next to note heads, which perhaps may have induced Chopin to add a second slur, embracing also the preceding crotchet. According to us, the slur was probably supposed to replace the previous one. A probability of Chopin's proofreading is also indicated by a possible trace of correcting the previous slur in bar 12. However, not being certain of the authorship of these changes, in the main text we leave the version of A.
