b. 283

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

..

The  indication is certainly a result of a mistake of the engraver of GE1 – see the next note.

b. 283-284

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

Slur in A (possible reading) & GE2

Slur in A (contextual interpretation→GE1FEEE)

..

Same as in bars 135-136, the placement and range of the slur of A are unclear – it can refer both to the quavers in the top voice and to the crotchet of the bottom one.

b. 283

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

Accent under R.H. in A

Contrary to the clear notation of A, in the editions the accent was assigned to the L.H.

The version of GE1 (→FEEE) is a result of Chopin's proofreading, which is proved by the traces of deletion of con the 5th quaver in the bottom voice. However, a more detailed analysis of traces of corrections in print proves that it was also gthat was being removed there. It means that Chopin most probably did not proofread the text of A, which was fine, but the false c1-a1-c2-gchord: . Concentrated on correcting the sound in the place of mistake, it is possible that the composer did not thoroughly check the context and resolved the e1-dseventh to the a1-cthird, particularly since a similar shape of accompaniment appears three bars later in bar 286, very similar in terms of harmony. Moreover, taking into account the possibility of an accidental removal of the correct cnote as a result of a misunderstanding at the time of implementing the proofreading, in the main text we give the version of A. The proofread version of GE1 can be considered an equal variant.

Slur to e2 in A

Slur to e2 in GE (→FEEE)

In the main text we give the version of A, in which Chopin marked the ending of the slur on the ecrotchet with a pronounced penstroke. The version of GE (→FEEE), probably proofread by Chopin, can be considered equal.
