b. 39-40

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

No slur in A (→GE1FEEE)

Slur in GE2

..

The slur for the bottom voice of the R.H. is an arbitrary addition of the reviser of GE2.

b. 40

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

Slur to e2 in A (→GE)

Slur to e​2 in FE (→EE)

..

In the main text, we give the ending of the slur after FE (→EE) due to a possibility of Chopin's proofreading. The text of A (→GE) may be considered an equal variant.

b. 41

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

..

b. 41

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

..

The natural before the initial third was misplaced in FE: before cinstead of a. The mistake went to EE1, where the "superfluous" sign was omitted. Chopin added the necessary sign in FED; EE2 (→EE3) also includes the correct text.

b. 43-44

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

1 slur in A

2 slurs in GE1 (→FEEE)

2 slurs in GE2

..

The slurs of the editions, although almost certainly arbitrary (typical whole-bar slurs for the engraver of GE1), do not substantially influence the performance: the break falls between notes at the same pitch (g2) and leading the slur in bar 44 to the end of the bar may be regarded as a slur-tenuto, used by Chopin on a number of occasions.
