b. 331

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

Minims in A & FE

Dotted minims in GE & EE

..

The missing dots extending the b-dthird in FE may mean that they could have been added in the last phase of proofreading of GE1. The authenticity of this addition is questionable (same as of a similar change in EE).

Our variant suggestion

..

In the main text we include – in a variant form – the fingering entered into AsI, complementing the fingering of A. The digit '1' added in FESB on the penultimate semiquaver in bar 331 is either a correct revision or a fortuitous mistake – in this edition there is no staccato mark over this note, which was perhaps interpreted as a digit.

In AsI and A there is no  to the 2nd semiquaver (E), while in A also no  to the 13th semiquaver (f). The accidentals were added in GE (→FE,EE). In AsI Chopin did not forget , since he enharmonically wrote the preceding note as f. In the main text we add a cautionary  to the 4th semiquaver (G).

The missing dynamic hairpins under the L.H. part are almost certainly a mistake by the engraver of GE1. It is difficult to determine the exact range of the marks in A, since their arms are of different length.
