Slurs

b. 368

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

Whole-bar slur in A

Slur over quavers in GE (→FE,EE,IE)

..

Similarly as in bar 185, in the main text we keep the A slur. The version of the editions can be considered an acceptable variant.

b. 373

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

No slur in sources

Slur suggested by the editors

..

As in bar 190, in the main text we suggest adding a slur after analogous bar 7, which is marked more accurately.

b. 376-378

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

Slurs from 2nd quaver in A

Slurs from 1st quaver in GE (→FE,EE,IE)

..

In bar 376 and 378 in the main text we keep the notation of the A slurs, as the comparison with analogous bar 10, 12 and 193 shows that Chopin – although he did not mark it here – most probably envisioned the initial octave to be performed staccato. However, one can understand the engraver of GE, who considered the A notation to be another case of inaccurate slurs (particularly the slur in bar 378, the ending of which is certainly inaccurate).

b. 383

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

Tie to c2 in A & EE

Slur f2-e2 in GE (→FE,IE)

..

In the main text we provide the A tie, clearly at the pitch of c2. The fact that in GE (→FE,IE) it was assigned to the middle notes of the chords (f2-e2), hence turning it into a slur, was an arbitrary decision by the engraver of GE. Moving the slur to the pitch of c2 in EE, hence restoring it to its initial form, a tie, was also arbitrary – the publisher did not have access to A, yet he interfered with the notation of the slurs/ties between the pairs of the L.H. chords in this place by adding slurs/ties in the next bar, in which Chopin did not write them.

b. 384-385

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

No slurs in A (→GEIE)

Slur in FE

Slurs in EE

..

The slurs/ties added in FE and EE, although certainly inauthentic, most probably correspond to the performance intended by Chopin.
The second slur added in EE is incomplete – its ending in bar 384 was omitted, in a new line.
