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.

b. 302-305

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

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).

f3 in chord in FE (→EE) & GE3

d3 in chord in GE1GE2)

..

A comparison with the five bars, which had already occurred, containing a similar procedure proves the mistake of GE1 (→GE2), corrected in GE3.

composition: Op. 16, Rondo in E♭ major

In GE, there is no  lowering d2 to d​​​​​​​2. A mistake is evidenced by a cautionary  before d2 in the next bar.
