b. 70

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

Slashed grace note in A

Grace note without slash in GE1

Medium-size crotchet in FE

Normal-size crotchet in EE

Grace note without slash in GE2

It is a very instructive example of how the accumulation of minor inaccuracies of subsequent editions transformed the acciaccatura in A into a regular crotchet in EE (the crotchet in FE is printed in a font of intermediary size, used in the orchestral part). All changes concerning the anote are most probably erroneous, whereas placing it over the rest in GE1 seems to have been forced by lack of space.
The fingering written in FED in the next two bars suggests that the fragment was developed in more details during lessons with Chopin. Therefore, one can ponder why the composer did not react to the erroneous notation of FED. According to us, performing the aas a crotchet could have been accepted by Chopin when phrased accordingly.

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.

The missing arpeggio mark in A before the 1st chord in the L.H. is a patent mistake, corrected already in GE (→FEEE).
