b. 321

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

..

In A (→GE) there are no accidentals in the last group of semiquavers. In the proofreading of FE (→EE) two flats were added, probably indicated by Chopin, a cautionary before A and a necessary one before G.

Two-bar slur in A, interpretation suggested by the editors

2 one-bar slurs in A (possible interpretation→GEFEEE)

..

In A bar 321 is the last one on the page, which became the cause of the ambiguous notation of the slurs in the R.H. – the slur in bar 322 (on a new page) suggests a continuation from the previous bar, which is not confirmed by the ending of the slur in bar 321. In the main text we assume that Chopin's intention was a two-bar slur, yet the version of the editions, with two one-bar slurs, can also be considered a justified interpretation of A.

..

Three flats before g notes visible in A, written later with a foreign hand, were not included in GE1. The same applies to the cautionary  before at the beginning of bar 324. The natural harmonic context allows to guess the correct text even without these signs; however, all doubts are dissipated by the Chopin proofreading of FE (→EE), in which all necessary flats in bar 322 were added as well as a cautionary  before A at the end of bar 323 and E at the end of bar 324. GE2 included the signs added in A, adding also a fourth one, a necessary  in bar 322 (before the penultimate semiquaver).

FE overlooked the  raising a to a. The patent mistake was corrected in EE. The correct text is also in A (→GE).

b. 325

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

..

In the main text we add cautionary flats before din the R.H. and in the L.H. When reading less carefully, it would be tempting to use a diminished four-note chord, well liked by Chopin, which, to a certain extent, is confirmed by the  written before din the 1st violin part in Morch
