composition: Op. 10 No 7, Etude in C major

..

In A there is no  lowering a1 to a1 in the chord on the 2nd quaver of the bar. It is a patent error, comprehensible when we realise that first Chopin wrote the part of the R.H., probably in a half-bar long fragments, and then he wrote the part of the L.H. At the moment of writing the discussed chord, a as an element of the prevailing harmony was already grounded in his awareness. The accidental was added in FE (→GE,EE).

GE with shifted accent

EE4 with two accents

The rhythm of A, interpreted literally, is unclear. Aligning the notes of the L.H. under the part of the R.H. suggests that Chopin thought of an analogous version to the version of bar 34 in this place. In the main text we adopt the version of FE (→EE3), as it is the latest authentic source, while the notation therein is faultless and unequivocal. The suggested variants include also different placement and number of accents in GE and EE4, most probably or certainly non-authentic.
