Slurs

b. 18

composition: (Op. 4), Sonata in C minor, Mvt I

No slur in A (→GEFE,EE,IE)

Slur suggested by the editors

..

In the main text we suggest here a slur modelled after the preceding bar, since there is no doubt that in this context both motifs should be performed analogously.

#FE2 also added a slur.

b. 21-22

composition: (Op. 4), Sonata in C minor, Mvt I

Slurs from a in A, literal reading

Slurs from f in GE (→FE,EE,IE)

..

In the main text we include the interpretation of both A slurs adopted by GE (→FE,EE,IE) – see the note on bars 17-20.

b. 24

composition: (Op. 4), Sonata in C minor, Mvt I

Tie to g in A & IE

Slur in GE (→FE)

No sign in EE

..

GE (→FE) put the tie to g under the bottom stave, which turned it into a vague curved line. EE omitted it, and it was only IE that guessed Chopin's intention.

b. 38

composition: (Op. 4), Sonata in C minor, Mvt I

No slurs in A

4 slurs in GE (→FE,EE,IE)

..

The GE slurs (→FE,EE,IE) were added by the publisher and are inauthentic. This kind of notation can be found in Chopin's works, especially in the early ones (cf., e.g. IV mov., bars 185-186 or the Variations in B, Op. 2, bar 266), yet in this case A simply does not contain slurs.

b. 39

composition: (Op. 4), Sonata in C minor, Mvt I

Slur in A

No slur in GE (→FE,EE,IE)

..

The absence of the slur in the editions most probably resulted from an oversight, as it is poorly visible in A.
