b. 302-304

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

Long accents in A

Short accents in GE (→FE)

Vertical accents in EE

..

The evident long accents in A in the middle of bars 302 and 304 were reproduced in GE (→FE) as short ones, whereas in EE they were changed to vertical. It is certain that none of the changes comes from Chopin.

b. 302-304

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

..

In bars 302 and 304, Chopin placed a natural before the bcrotchet in A (→GE1FEEE). In the main text we omit those superfluous signs. The naturals were removed also in GE2. The signs reveal Chopin's way of thinking, considering the top and bottom voices independently – cf. the 3rd mov. of the Concertobar 422.

Wedges in A

Dots in GE (→FEEE)

..

The quavers opening these bars are provided with clear wedges in A. Reproducing them as staccato dots is a very frequent inaccuracy of GE (→FEEE).

Crotchet c1 in A (literal reading→GEFEEE)

No crotchet in A (contextual interpretation)

..

The alleged additional crotchet stem next to cvisible in A is, according to us, an exceptionally imposing trace of Chopin's reflex at the time of writing notes on ledger lines. In order to secure visibility of such a note, the composer would give the note head the shape of a vertical line – see analogous note in bar 303. Sometimes, particularly when writing in haste (as in this case), the lines were long enough to look like a crotchet stem pointing downwards (a slightly shorter line in bar 301 did not mislead the engraver). See also the Etude in F major, Op. 10 No. 8, bars 4-7

The cautionary flat before ewas added – perhaps by Chopin – in the proofreading of GE (→FEEE).
