b. 378

composition: Op. 16, Rondo in E♭ major

Long accent in FE

Short accent in GE & EE

..

The accent mark in FE is slightly but distinctly longer than the short accents in the previous bars. However, the remaining editions found this difference negligible.

b. 378

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

..

In FEH, the tied g1 quaver is slashed. It is most probably an additional signal reminding that the note should not be played.

b. 379-380

composition: Op. 21, Concerto in F minor, Mvt III

No slurs in A

Slurs in GE1 (→FE)

Slur in EE & GE2

..

It is difficult to assume that the slurs in the L.H. appearing in GE1 (→FE) could have been added in this form by Chopin – they are contrary to the authentic slur in the R.H., whereas their range overlaps with the beams of the group of quavers. Therefore, it is most probably a revision, which also questions the authenticity of the slurs added in GE1 in the previous two bars. The revisers of EE and GE2 replaced them with a two-bar slur modelled after the slur of the R.H.; it specifies the notation, yet it does not follow from the notation of A.

b. 379-380

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

No slur in FE (→GE)

..

The slur in EE was most probably added after the slur featured in the analogous situation four bars earlier. It would be justified if it were not for the fact that the slur in bars 375-376 could be inaccurate.
