b. 317-318

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

2 slurs in A, EE & GE2

1 slur in GE1

No slurs in FE

..

The omission of one (GE1) or both (FE) slurs over the pairs of bass notes is certainly a mistake. The slurs were added in EE and GE2.

b. 317

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

Two 3-quaver slurs in A & GE2

3- & 4-quaver slurs in GE1

3- & 5-quaver slurs in FE

Two 4-quaver slurs in EE

..

The second slur in FE is almost certainly erroneous (perhaps it is a mistake repeated after the original version of GE1, which was then corrected in the last phase of proofreading). The version of EE, certainly contrary to Chopin's intention, is probably an attempt to organise slurs over similar figures in bars 316-318.

b. 318

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

No slur in A

4-quaver slur in GE1 (→FEEE)

3-quaver slur in GE2

..

The absence of the last of the three-quaver slurs in the L.H. is almost certainly Chopin's oversight. The slur was added in GE1 (→FEEE), by embracing the entire 2nd half of the bar with it. According to us, the addition can come from Chopin; however, it was most probably misinterpreted by the engraver. In GE2 the slur was shortened after previous figures, which we give in the main text as probably corresponding to Chopin's intention.

Same as in analogous bars 169-170, in A (→GE) there are no flats restoring a at the beginning of the 2nd half of each bar. The mistake was corrected in FE (→EE), probably at Chopin's request.

The first note in the top voice in A (→GE1FEEE) is an erroneous double dotted quaver. Moreover, the assignment of the middle note in the 1st chord is unclear; e2 – the head, devoid of a stem, could be combined with ain the top voice (as in the previous bar) or with din the bottom one (as in analogous bar 170). The editions repeated the layout of the previous bar, at the same time assimilating the value of ewith a2. The editors of mUltimate Chopin are inclined to the second possibility, suggesting in the main text a solution fully analogous with the version from the exposition.
