b. 317

composition: Op. 2, Variations, complete

2 wedges in A

Wedge in GE1 (→FE,EE,GE2FESB)

Missing wedges result from oversights by the engravers of GE1 and GE3.

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.

composition: Op. 11, Concerto in E minor, Mvt I

No accidental (d3)  in FE (→EE,GE1GE2)

 (d3) in GE3

 (d3), our alternative suggestion

..

There is no accidental before the penultimate semiquaver in the majority of the sources. When interpreted literally, it is a ddue to the  before the 2nd semiquaver. This version, inconsistent notation (e2-d3) aside, implements the harmonic scheme of such figures in bars 315-318, using chord elements only, and we give it as such in the main text, adding a reminding  before the discussed note. However, one cannot exclude an oversight of the alteration's cancellation by Chopin, which is one of his most frequent mistakes. The version with d3, resulting from such an assumed mistake, continues the melodic and pianistic scheme defined in the two previous figures, which we suggest as an acceptable variant.

The sources feature a cautionary  before cand a reminding one before ain the 3rd chord. In the main text, we omit both marks, which are, according to us, unnecessary. In turn, we add a cautionary  before e2
