b. 144

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

Long accent in A

 in GE (→FEEE)

..

Even if we consider the sign of A to be , the editions reproduced it inaccurately, extending it until the 4th quaver. However, the sign in A is almost certainly a long accent – cf. a sign of the same length on the last crotchet as well as a number of others, e.g. in bars 118-120, 125, 133.

b. 144

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

Quavers c in A (→GE)

Crotchets in FE (→EE)

..

Both stems extending the notes were undoubtedly added by Chopin in the proofreading of FE (→EE).

b. 145

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

Slur from 2nd quaver in A (probable reading) & GE2

Slur from 1st quaver in A (possible reading→GE1FEEE)

..

The starting point of the slur in the L.H. in the 1st half of the bar is unclear in A, since it partially blends in with the con forza indication. We assume that the slur runs from the 2nd quaver, since such slurs are present in bars 241-246, based on a similar texture, as well as in bar 32 and 81 in the 2nd movement of the Concerto. The version of the majority of editions may, however, be considered an equal interpretation.

b. 145

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

No slur in GE1 (→FE)

Slur in EE & GE2

..

The slur in the 2nd half of the bar, added in GE2 and EE is certainly arbitrary, although the analogy with the 1st half of the bar certainly encourages an addition. However, it is puzzling that the reviser of EE added a slur from the 2nd quaver, although in the 1st half of the bar EE has a slur from the 1st quaver.

b. 145

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

..

None of the sources includes the correct notation of accidentals, although omissions do not impede the interpretation. In A there is no  raising d1 to don the 4th quaver (it is also absent before the 7th quaver) and d2 to dat the end of the group of demisemiquavers. In GE (→FE) the last sign was added and a  before on the 6th quaver was repeated, whereas GE2 removed the superfluous  before the second b2. EE is closest to the correct notation, in which the only inaccuracy, perhaps resulting from a different approach to such situations, is a missing  before don the 7th quaver – a  already appeared in this bar before a note at this pitch, yet in another clef (on the 4th quaver).
