b. 249

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

Short accent in sources

Long accent suggested by the editors

..

In this context, a short accent is almost certainly a result of misunderstanding Chopin's notation. In bar 225, Chopin used a long accent, in bar 233 – a vertical one; therefore, in the discussed bar he probably meant a long accent.

Staccato dots in A (→FCGE)

No marks in FE (→EE)

..

The missing dots at the beginning of the bar (in both hands) is almost certainly an oversight of the engraver of FE (→EE).

Slur to f in A

No slur in FC

Slur to d1 in FE (→EE) & GE

..

When interpreted literally, the slur of A encompasses only the quavers. A comparison with the analogous figures proves Chopin's inaccuracy, corrected already in FE (→EE). The missing slur in FC must be an oversight of the copyist, corrected already in GE1 (→GE2GE3).
