b. 5-8

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

No fingering in A (→GEFE,IE)

Fingering in EE

..

In the main text we omit the inauthentic fingering added by EE in bars 5-8 (R.H.) and in bar 6 (L.H.).

b. 6-8

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

Slurs to g1 in A, literal reading

Slurs to e1 in A (contextual interpretation→GEFE,EE,IE)

..

The range of the A slurs in bar 6 and 8 is unclear – the former, ending between g1 and e1, could be interpreted as a slur encompassing the entire L.H. passage, yet the latter clearly ends on g1. As there is no reason for the range of the slurs to differ, we consider slurs ending on g1 as the A text, since they are closer to the literal interpretation. On the other hand, in the main text we provide the interpretation adopted by the editions, certainly more justified, both musically and pianistically speaking.

b. 8

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

in A

No sign in GE (→FE,EE,IE)

..

The missing  hairpin is probably due to an oversight by the GE engraver (→FE,EE,IE).

b. 9-10

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

Slur in upper part in A, probable interpretation

Tie to a1 in GE (→FE,EE,IE)

..

The meaning of the slur/tie led in A under the top voice notes is unclear. In GE (→FE,EE,IE) it was reproduced as a tie to the last a1 crotchet in bar 9; however, according to us, it is more likely that Chopin meant a slur, writing it with the chromatic step in the top voice in mind. It is indicated by the slur's position – a tie concerning a1 could have been written at the pitch of this note or slightly below. Therefore, in the main text we provide a slur concerning the top voice, placing it over the notes for the sake of clarity.

b. 9-10

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

Slur from c to f1 in A, literal reading

Slur from A to e1 in GE (→FE,IE)

Slur from a to e1 in EE

Slur from A to d1 suggested by the editors

..

The fact that the A slur starts from the 3rd quaver in the bar most probably results from the difference in the direction of stems and beams – as Chopin wanted to write a slur on the side of noteheads, he omitted A, which is pointing upwards.
The musically unjustified rupture of the slur before the end of the passage is most probably also due to a graphic reason – a slight gap between the parts of both hands at the end of the bar. This is how it was assessed in the editions, in which, however, the slur was led only to the end of the bar, which can be considered an acceptable variant (except the arbitrary EE version, perhaps accidental).
