Issues : Inaccuracies in A

b. 474-475

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

..

In A, Chopin marked correctly only the first out of three notes requiring an accidental in both passages – b in bar 474 and c3 in bar 475. All necessary signs were added already in GE (→FeEE). Moreover, a cautionary  was added before fat the beginning of bar 474. In the main text, we also add a cautionary  before g2 in bar 475.

b. 478-479

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

..

Just like in the previous passages, Chopin wrote the necessary accidentals in A only in the first triplet in each bar. All necessary signs, including the cautionary  before fin bar 479 were added in GE (→FEEE). Moreover, GE2 added two more cautionary naturals before f2 and f. In the main text, we omit the latter.

c4 & c3 in A (literal reading→GE)

Thirds in A (contextual interpretation) & FE (→EE)

..

The absence of aand aon the 1st and 4th quavers in the bar in GE must be attributed to an extremely inaccurate notation of A in this respect; according to us, Chopin did write these notes in that place, yet, being in haste, he did not check whether they are visible in the place where the stems overlap with ledger lines. The fact that both notes were added in the proofreading of FE (→EE) dissipates all doubts regarding the composer's intention.
