b. 316

composition: Op. 2, Variations, complete

Slur in A

No slur in GE (→FE,EE)

..

The absence of the beginning of the slur the ending of which can be seen in a new line in bar 317 must be a mistake by the engraver of GE (→FE,EE). See bar 317.

b. 317

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

No indication in sources

[a tempo] suggested by the editors

..

According to us, the chromatic descending scale must be performed a tempo. It is possible that Chopin had to be satisfied with the marking leggieremente, which suggests a change of approach – the passages in bars 311 and 315, in spite of the very neutral dynamics, are not associated with "lightness." The ritenuto appearing in bar 324 may be considered an additional argument for changing the tempo in bar 317.

b. 317

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

leggieramente in A & GE2

leggiermente in GE1, contextual interpretation

leggieremente in FE

leggiero in EE

..

In the main text we adopt the newer form of this adverb, introduced in GE1 (we correct the erroneous 'o' at the end of the word to an 'e').

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.
