b. 142

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

No mark in FE (→GE1GE2, →EE1EE2)

Short accent in GE3 & EE3

Long accent suggested by the editors

..

Accents are present in 11 similar figures of this and previous, analogous phrases, so that the missing mark in the indicated place must be considered an inaccuracy. In the main text, we add a long accent in accordance with the accents used in FE. The short accent added in GE3 and EE3 corresponds to the accents adopted in those editions.

b. 142

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

In FEH, there is an added cautionary  before d1 on the 2nd quaver in the L.H. It is difficult to determine what the motivation of the person adding that accidental was, since nothing suggests here a possibility of a mode change, whereas the last alteration of d​​​​​​​ took place more than 80 bars earlier.

composition: Op. 22, Polonaise

..

There are no accidentals before the 4th and 8th semiquavers in FE (→EE,GE). The natural put before c4, the last note in the bar, proves that Chopin considered the  from before the 1st quaver of the bar to be valid up until this place, thus regarding the aforementioned notes as c2 and c3 (cf. a similar situation in b. 144). In accordance with the contemporary rules of chromatic orthography, we provide the discussed notes with sharps.

Mordent in FE

No ornament in GE & EE

..

The absence of a mordent both in EE and GE suggests that we are dealing with an oversight of the engraver of FE, which made its way to these editions; however, in FE it was corrected in the last stage of proofreading. In the main text we add an accidental – often omitted by Chopin in such situations – specifying the pitch of the mordent's top note.
