b. 207

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

No slur in sources

Slur suggested by the editors

..

The missing slur must be considered Chopin's or the engraver's mistake – in the remaining analogous bars, there are slurs, although inaccurate. In the main text, we suggest a slur modelled after the slurs of the sources in bars 205 and 209.

b. 207

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

..

In FE, a  is only before the top note of the octave on the 2nd beat of the bar. The patent mistake was corrected in the remaining editions by adding a  before the bottom note, whereas in EE and GE3, the unnecessary  before the top note was also removed.

b. 208

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

Slur from first octave in FE (→GE,EE)

Slur from 2nd octave suggested by the editors

..

In this context, two identical octaves at the beginning of the bar, the slur of the sources is almost certainly inaccurate. It could have been the revisers or even Chopin himself that did not notice it due to the enharmonic change of B1-B to A1-A.

b. 210

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

Short accents in FE (→GE)

Vertical accents in EE

..

Changing the accent's font to vertical is a characteristic manner of the engravers of EE

b. 211

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

..

In the main text, at the beginning of the bar, we add a cautionary  also in the R.H. We also add a  before the 4th semiquaver, f3, and a  before the 9th semiquaver, a3. The latter was introduced already in GE and EE2 (→EE3).
