b. 282

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

..

FE1 has an a1-cthird on the 1st quaver. It is a perfect example of an unfinished proofreading, where the correct note was printed without having removed the erroneous one. The mistake was corrected in FE2 (→EE).

b. 286

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

..

There is a cautionary  before din the sources, written by Chopin probably in order to avoid a ddue to bin the R.H. and a very frequent use of diminished triads and four-note chords. We omit this sign in the main text, since the d-f-b chord used in this place was highlighted two bars earlier.

f-f1 in A (→GE) & FE2 (→EE)

d-d1 in FE1

..

The version of FE1 must be erroneous, which is proved by a comparison with analogous bars 286 and 290 as well as by the proofreading of FE2 (→EE), perhaps originated by Chopin.

b. 294

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

..

The sources include a cautionary  before dat the beginning of the bar. In FE (→EE) and GE2 a respective sign was added also next to d in the L.H. We do not include these signs in the main text, since it is d that has been exclusively present for more than 20 bars and not d. Cf. bar 298.

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

..

A has an aas the last note in the L.H. It is almost certainly a mistake – cf. analogous figures in bars 300, 302 and 304-306. Mistakes in the number of ledger lines are the most frequent pitch errors committed by Chopin (excluding those related to the notation of accidentals). GE (→FEEE) features the correct text, which can be ascribed to Chopin's proofreading or a fortunate mistake, since there are no visible traces of correction in print, whereas the note in A, despite three ledger lines, is written lower than the previous g1.
In the discussed place, there is a visible correction in A. The deletions are actually very precise, yet their placement allows us to indicate e1 and das possibly crossed out original (or only erroneous) last two notes.
