b. 311-312

composition: Op. 11, Concerto in E minor, Mvt I

Slur in FE

Slur in GE1 (→GE2)

Slurs in EE

Slurs in GE3

Slurs suggested by the editors

..

The missing slur in the first half of the bar is probably an oversight, either of the engraver of FE or Chopin, cf. analogous bar 295. However, the slur added in EE is almost certainly arbitrary, whereas the one in GE3 – modelled after the most probably inaccurate slur in the aforementioned bar 295. In the main text, we suggest adding a slur in the entire first half of the bar, just like in bar 295.
The second slur in the discussed bar, written too early, is an inaccuracy of GE

Although the  marking was probably not written by Chopin's hand, it may be an authentic teaching comment – cf. dolce in analogous bar 295.

Staccato dot in FE (→EE)

The lack of staccato dot for the equaver is most probably an oversight of the engraver of GE.
