b. 354

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

Long accent in A

Short accent in GE & EE

No mark in FE

..

Shortened accents are a very frequent inaccuracy of GE, whereas the omission of the sign in FE is a patent mistake, revised then in EE.

b. 354

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE, one can see traces of removal of wedges over the 1st and 2nd crotchets in this bar. The engraver most probably mistook this bar for the next one.

b. 354-355

composition: Op. 11, Concerto in E minor, Mvt III

No slur or tie in FE (→GE)

Tie to ​​​​​​​G1 in EE (probable reading)

Slur in EE (different reading)

..

The curved line added in EE was probably supposed to indicate a hold of the G​​​​​​​1 quaver until the next bar. However, it is not entirely certain, since the status of the authentic staccato dot under that note is uncertain – one dot merged with the slur running over the stave placed below, whereas the second one, placed next to it, is so poorly visible that one can consider it to be a remaining element after the removal of that mark.

b. 354

composition: Op. 2, Variations, complete

No slur in sources

Slur suggested by the editors

..

In the main text we suggest adding top voice slurs. In general, the notation of slurs in this orchestral insert is inaccurate in A and most probably was not reproduced correctly in the editions – see further notes in this bar.

b. 354

composition: Op. 2, Variations, complete

Tie to b1 in AsI, A (→possible reading of GE1EE) & GE3

Slur over 4 quavers in GE1 (→FE,GE2FESB)

..

The curved line written in A between the voices is at the pitch of b1 and almost certainly indicates that the dotted crotchet at this pitch should be sustained, as clearly marked by Chopin in AsI (both in the piano part and in the clarinet II part). In GE1 (→GE2) the endings of the tie are placed lower and not horizontally, which makes the tie seem to concern 4 quavers in the bottom voice. This is how it was reproduced in FE and FESB (as a slur), whereas in EE and GE3 it is undoubtedly a tie to b1.
