b. 23-24

composition: (Op. 4), Sonata in C minor, Mvt I

..

In the main text we include the cautionary accidentals added already by GE (→FE,EE,IE) – the flats to e3 in both bars and the  to c3 in bar 24.

b. 24

composition: (Op. 4), Sonata in C minor, Mvt I

Tie to g in A & IE

Slur in GE (→FE)

No sign in EE

..

GE (→FE) put the tie to g under the bottom stave, which turned it into a vague curved line. EE omitted it, and it was only IE that guessed Chopin's intention.

b. 24

composition: (Op. 4), Sonata in C minor, Mvt I

Long accent in A (→GEEE,IE)

in FE

..

We interpret the A mark as a long accent, as it is graphically related only to the minim at the beginning of the bar. We similarly assess the slightly longer marks in GE, IE and EE. On the other hand, the FE mark is clearly longer, hence we reproduce it as a  hairpin.

b. 26-28

composition: (Op. 4), Sonata in C minor, Mvt I

..

In the main text we add cautionary flats to b2 in bar 26 and 28 and to b in bar 28. All accidentals were already added by GE (→FE,EE,IE).

b. 28

composition: (Op. 4), Sonata in C minor, Mvt I

Crotchet d2 in A

Quaver d2 in GE (→FE,EE,IE)

..

The version of the editions, in which the last d2 note is a quaver attached to the L.H. part, resulted from a misunderstanding of the misleading A notation – the d2 crotchet stem (bottom R.H. voice) almost reaches the e1 quaver written on the top stave.
