b. 414

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

..

In FE (→EE1EE2) a  was placed before b2, which is a mistake. Such a developed version, with a b2-dthird, is conspicuous only when performing the piece with orchestra (din the viola part), which may have contributed to the absence of a correction in EE1, generally carefully revised. In EE3 the  before b2 was preserved; in addition, a second one was added, lowering d3 to d3

b. 415-417

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

..

In A, bars 415 (from the 2nd beat), 416 and the 1st quaver in bar 417 are written an octave lower, since they were not encompassed with the octave sign. This patent mistake was corrected – perhaps by Chopin – already in GE1 (→FEEE, →GE2).

b. 415-423

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

..

A (→GE) features a das the penultimate quaver in bar 415. In the proofreading of FE (→EE), Chopin changed the notation of this note to e2. He performed an identical change in the notation of the topmost note of the chord on the penultimate quaver in bar 423. Similarly in bars 455 and 463.

b. 416

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

..

In A (→GE) the crotchet of the bottom voice is written as a g2. Similarly, the bottom note of the 3rd quaver is a g1. While proofreading FE (→EE), Chopin changed the notation of both notes to a2(1), in accordance with the way in which he wrote all subsequent appearances of similar bars.

b. 416

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

g1 in chord in A (→GE)

e1 in chord in FE (→EE)

..

The version of A (→GE) is most probably the original review of this chord, left by inadvertence (haste). It is proved by the undoubtedly Chopinesque proofreading of FE (→EE) and by the corrections visible in A in the repetition of this bar (bar 456).
