b. 428

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

No sign in A (→GEFEEE1EE2)

Arpeggio sign in EE3

Arpeggio sign suggested by the editors

..

We suggest adding an arpeggio mark in the main text, since the arpeggio written in A in bar 428 is, according to us, to be regarded as the model for all analogous bars (including 466 and 468). The wavy lines were added already in EE3.

Differently than in analogous bar 426, there is no cautionary  before b in A (→GE1FEEE), yet there is a  before e1, unnecessary in this context. In GE2, a  was added to the . In the main text we give a more logical notation, used by Chopin in bar 426 as well as in two analogous places (bars 466 and 468).
The sources include a superfluous  also before ein the R.H. Cf. bars 413-415.

b. 428-429

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

Slur to bar 429 in FE (→EE,GE1GE2)

Slur in bar 428 in GE3

..

The revision of GE3 does not seem to be justified, since visible traces of changes prove that the slur of FE was proofread, probably by Chopin, whereas both the original and the changed slur reached the 1st sixth in bar 429.

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

In FE, there are no sharps before the 6th semiquaver in the L.H. (c​​​​​​​2) and the middle semiquavers on the 3rd beat of the bar in the R.H. (c3 and d3). All those patent inaccuracies were corrected in GE, whereas in EE it was only the mark in the L.H. that was added.
