b. 277-278

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

Slur to e3 in FE (→GE,EE)

Slur to c4 suggested by the editors

..

According to us, leaving cwithout articulation markings is an inaccuracy, even if it corresponds to the notation of [A]. In the main text, we suggest extending the slur from the previous bar, in accordance with the rhythmic shape of the figuration.

b. 277

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

No mark in FE (→EE,GE1GE2)

Wedge in GE3

Wedge suggested by the editors

The missing staccato mark is most probably an inaccuracy. It is indicated by the wedge in the analogous situation in bar 273 as well as by the wedge on e​​​​​​​ in the L.H. The mark was added in GE3
