b. 157

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

F in A & GE2

D in GE1 (→FEEE)

..

The quaver, present in A, is probably the original version – cf. the ascending sequence of bass in analogous bars in the recapitulation (bars 301, 303 and 305). In the main text we give introduced most probably by Chopin in the proofreading of GE1 (→FEEE) and analogous to preceding bars 151, 153 and 155.

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

..

In A Chopin overlooked two naturals necessary on the 4th quaver in the bar (a and e1). GE1 (→FEEE) added a  raising a to a. GE2 has the correct text.

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

In the 2nd half of the bar, Chopin overlooked naturals in A – undoubtedly necessary – before the 2nd and 3rd quavers in the L.H. In GE1 (→FE) a sign was added before e1, while in EE and GE2 also the one before a.
