b. 325-327

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

Slur in A, literal reading

Slur in A (contextual interpretation) & GE2

No slur in GE1 (→FEEE)

..

In A bar 325 is the last one on the page. The slur in the L.H. clearly suggests a continuation (similarly as the slur in the R.H.), which, however, is absent on a new page (in bar 326). In GE1 (→FEEE) the slur was completely overlooked, whereas in GE2 the slur of A together with the overlooked ending was restored. Since this is how Chopin's intention undoubtedly looked like, in this case in the main text we include the slur of GE2.

b. 326-327

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

Slur in A, literal reading

Slur in A (contextual interpretation→GEFEEE)

..

When interpreted literally, the slur of A does not exceed bar 326. However, its shape suggests leading it to the beginning of bar 327, which is confirmed by the corrected – most probably by Chopin – slur of GE (→FEEE).

Slur in GE2

The slur of GE2 was probably added due to the slur in the previous bars.

Two cautionary signs were added in EE – a  before e1 and a  before g1. In the main text we include the latter; moreover, we add a  before b

..

In A there is no  lowering g2 to gbefore the 8th semiquaver. Chopin's patent oversight was corrected already in GE1. In such a situation, a  should be added before g3, appearing three semiquavers later at the same pitch, which was not done until in FE (→EE) and GE2.
