b. 316-317

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

..

In FE, both the  raising a2 to ain bar 316 and the  raising c3 to cin bar 317 are missing. These patent inaccuracies, most probably repeated after [A], were corrected both in GE and EE. The latter was added also in FED.

The version of GE is most probably a mistake, although, just like in the case of the majority of Terzverschreibung errors, it is possible to accept the sound result. Admittedly, the bar does not repeat the previous harmonic scheme, yet the melodic analogy remains clear, and changing the final interval would distort, for no apparent reason, the octave line implemented from bar 315:

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

 (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

b. 320-321

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

..

In each of three analogous bars (bars 319-321), the sources feature a cautionary  before the 1st semiquaver of the 3rd beat. According to us, when the figure is repeated, in bars 320-321, the marks are no more necessary.
