b. 109-110

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

d2-d2  (?) in A, literal reading

d2-d2 in A (contextual interpretation→GEFEEE)

..

In both bars there are no accidentals both before the 12th and the 13th semiquavers in A. The flats added in the proofreading of GE (→FEEE) – almost certainly by Chopin – confirm that we are dealing here with a rare case of a fourfold composer's error, who overlooked both the naturals altering d2 to dand flats returning d2. Both necessary naturals were added in EE and the first of them (in bar 109) also in GE2. This kind of mistake may seem implausible, yet in the notation of A, in which the 2nd and 3rd groups of semiquavers are written an octave lower with the use of the octave sign, the error does not seem so striking:

  • the discussed notes are not next to each other, hence a juxtaposition of two identical notes, which do not have accidentals, yet they sound differently, is absent;
  • naturals before d2 seem to be obvious after naturals in both hands in the 1st half of each bar;
  • d2 are sounds of the fixed, current key, F minor, hence the absence of flats is a typical Chopin oversight of cancelling alterations.

b. 109

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

..

In A there is a visible deletion of a sign over d2. It was most probably a mordent, which Chopin preserved as a diversification of the repeating phrase in bar 110.

b. 109

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

No c1 in chord in A & FE (→EE1)

Chord with c1 in GE & EE2 (→EE3)

..

GE has an additional note, c1, in the crotchet chord. The notation of A may be misleading here, yet Chopin's having deleted the note in the proofreading of FE (→EE1) is decisive. In EE2 (→EE3) the note was added under the influence of GE1.

b. 109-110

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

Long accents in A (→GEFE)

Short accents in EE

..

The long accents over the syncopated chords in the L.H. were reproduced quite accurately in the editions, except for EE.

b. 109-111

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

2 slurs in A & GE2

Slur in bars 110-111 in GE1

No slurs in FE (→EE)

..

The slurs over the pairs of chords at the transition between bars 109 and 110 and 110 and 111 were overlooked or inaccurately reproduced in the majority of the editions. GE1 includes a slur under notes in bars 110-111. It is uncertain whether it is a misread slur introduced by Chopin in the proofreading of GE1 as a tie of f. In FE (→EE) there are no slurs mentioned above, whereas GE2 restored the notation of A.
