Issues : Accidentals in different octaves

b. 19-20

composition: Op. 10 No 2, Etude in A minor

..

In none of the authentic sources the notation of the accidentals in the part of the R.H. is entirely correct in these bars – particularly in bar 19. However, the inaccuracies do not pose problems in establishing the correct text. Moreover, in all sources except for Ap the unnecessary  before f2, the 14th semiquaver in bar 20, is repeated.

d-a-c1 in CLI (interpretation)

c-a-b in Ap

d-a-b in FE (→GE,EE

..

In the sources there are three enharmonically different forms of this chord. Two of them are inaccurately written: in CLI there are no flats lowering d to d and a to a and in FE there is no  lowering d to d (which was corrected both in GE and EE). In the main text we give the notation adopted by Chopin in the version for publication. Cf. bar 22.

..

Ap is missing a  next to the lower note of the octave at the beginning of the bar. This patent error is one of a few inaccuracies of this autograph's notation.

Semibreve in CLI

Version in #Ao & FE (→GE,EE

..

The semibreve in CLI is undoubtedly the original version. In the final version Chopin enriched the sound and made the rhythm more robust. In Ap  before the lower note of the first octave is missing. In Ap and FE there is no  lowering e1 to e1 on the 2nd beat of the bar. This patent inaccuracy was corrected in GE and EE. In GE3 and EE4 an unnecessary  before the 2nd e is also added.
