Long accents in FEcor

Short accents in FE (→GE,EE

The clearly long accents, written by Chopin in FEcor, were recreated in FE (→GE,EE) as short ones. Ap has even characteristic  marks before the accents, which are typical for this autograph. In the version for printing Chopin did not use any of them.

Two  signs in Ap

Accent in EE2, interpretation

Two accents in EE3 (→EE4), interpretation

The  hairpins added in one of the later proofreadings of FE (→GE) should be, according to us, interpreted as diminuendo (in pair with the  sign in the previous bar). However, it must be said that FE also reproduces a few unequivocal long accents in a similar way. This is exactly how the sign was understood in EE and, moreover, in EE3 (→EE4) a similar accent was arbitrarily added in analogous place in bar 26.
Ap has  in both bars, while in bar 25 the sign is put clearly earlier than in FE.

Wedges & dots in Ap

Dots in FEcor

Dot in FE (→GE,EE

In the main text we give three staccato dots, at the beginning of bars 25-27, written by Chopin in FEcor. In finished FE (→GE,EE) only the dot in bar 26 was printed. Ap displays a richer set of staccato markings.

No slurs in CLIFE (→GE,EE

Slurs in Ap

..

The slurs of Ap belong to this kind of indications that, according to us, combine well with the markings of the version for printing.

Crotchet in CLIFE (→GE,EE

Quaver in Ap

It is hard to determine Chopin's motivation at the time when he was writing the e-e1 octave in Ap as a quaver. In the version for printing he returned to the original value of a crotchet.
