b. 244

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

..

The bar is not written correctly in any of the sources. In A four signs are missing: a  before the 5th semiquaver (d2) and flats before the 7th semiquaver (b) and before the last two semiquavers (b2 and d2). In GE (→FEEE) only two signs were added: a necessary  before the 5th semiquaver (d2) and a cautionary  before the 14th semiquaver (d3). Moreover, A repeated a  before the bottom note of the last quaver in bar 244. The unnecessary sign was removed in EE1 (→EE2) and in GE2, but it was restored in EE3.

..

In the main text we add a cautionary  before f1.

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

Long accent in A

Short accent in GE

No mark in FE (→EE)

..

The change of the type of accent in GE is a very frequent inaccuracy in Chopin first editions. The absence of the accent in FE (→EE) is probably one of the mistakes committed while proofreading bars 243-244 – cf. notes in the previous bar.
