Slurs

b. 20

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

No slurs in sources

Slurs suggested by the editors

..

In the context of three analogous bars, bar 18, 19 and 21, the missing slurs must be considered Chopin's inadvertence. Due to the above, we add them in the main text.

b. 27

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

Slur in A (→GEEE,IE)

No slur in FE

..

The missing slur is an oversight by the FE engraver.

b. 31-32

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

Long & 2 short slurs in A

2 short slurs in GE (→FE,IE)

3 short slurs in EE

Long slur suggested by the editors

..

In the main text we omit the additional slurs over the first two triplets – cf. General Editorial Principlesp. 16. On the other hand, in GE (→FE,EE,IE) the longer, top slur was omitted. 
The third triplet slur added in EE was an arbitrary decision by the reviser of this edition, justified in the face of the absence of a slur encompassing the entire passage.

The starting point of the L.H. slurs in bar 33 and 35 in A can give rise to doubts – they actually begin on the 2nd beat. However, it is contrary to the slurs of the analogous motifs in bars 1-4, hence in the main text we consider the beginnings of these slurs to be inaccurate (incidentally, in bar 33 the slur may suggest an earlier starting point; see also the note on inaccurate slurs in mov. I, bars 17-20). The GE slurs (→FE,EE,IE), completely arbitrary, refer to the R.H. slurs at the beginning of the Minuet.

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

Slur in bar 34 in A

Longer slurs in b. 34 & 36 in GE (→FE,EE,IE)

Slurs in b. 34 & 36 suggested by editors

..

In A there is only one slur in the R.H. part, encompassing 2 quavers in bar 34. Taking into account the more careful L.H. markings (slurs in bar 33 and 35), in the main text we add an analogous slur in bar 36. A similar addition was also introduced by GE (→FE,EE,IE), yet both in bar 34 and 36 the slur starts from the 1st crotchet in the bar (as the L.H. slurs in bar 33 and 35 do).
