a2f2 tied in A (→FCGE) & EE

The omission of the ties of a2 in b. 318-319 and of f2 in b. 324-325 in FE may be a result of misinterpretation of Chopinesque very short ties as endings of motivic slurs over the bottom voice motifs: see b. 310-323. The ties were added in EE.

In the main text we reproduce the notation of A, emphasising, as it seems, the syncopated quavers in the top voice. The shifted marks in the editions are gathered around the beginnings of the even triplets, which could not have been Chopin's intention – marks of such range cannot concern the top voice, next to which they were written.

b. 319-320

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

..

Same as in analogous bars 169-170, in A (→GE) there are no flats restoring a at the beginning of the 2nd half of each bar. The mistake was corrected in FE (→EE), probably at Chopin's request.

b. 319

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

..

The cautionary flat before dwas added in GE (→FEEE). It may be a revision; however, it is worth observing that four bars later, a corresponding sign in an analogous figure is written already in A
