b. 320

composition: Op. 44, Polonaise in F♯ minor

F tied in GE, FE & EE2 (→EE3)

F repeated in EE1

..

The missing tie to F in EE2 must be a mistake, corrected in EE2 (→EE3).

b. 320

composition: Op. 44, Polonaise in F♯ minor

..

In the main text we add a cautionary  to E. In the next two bars the sources contain respective accidentals.

b. 320

composition: Op. 2, Variations, complete

Accent in AsI

Accent & wedges in A (→GEEE)

No marks in FE & FESB

..

The left-out accent and wedges must be a mistake by FE and FESB. In the case of FE1 (→FE2), according to us, the possible reason could be – as in the previous bar – the introduction of the ossia più facile version, marked by the use of a smaller font (see the note in bar 319).

b. 320

composition: Op. 2, Variations, complete

Slur in A (→GEEE,FESB)

No slur in FE

..

The missing slur in FE must be a mistake, as in the case of the accent and wedges – see the previous note.

b. 320

composition: Op. 2, Variations, complete

..

The sources do not include an accidental over the mordent. In this harmonic context, the use of b is obvious, hence in the main text we add a  over the ornament. Chopin hardly ever put accidentals over trills or mordents in such situations, generally leaving the task of finding the right sound of the auxiliary note to the performer's imagination.
