Issues : Accidentals in different octaves

b. 37-40

composition: Op. 10 No 8, Etude in F major

..

The sources differ in the presence of accidentals, which, however, does not raise any doubts concerning the text's interpretation. Considering the fact that Chopin and a part of his editors used slightly different rules of validity of the signs written with the use of the octave sign, we state that A is missing two necessary signs, a  before the bottom note of the octave at the beginning of bar 37 (B) and a  before the 14th semiquaver in bar 38 (e1). In FE (→EE) only the 1st of them was completed, in GE – both. According to the rules which are generally applied today, we also consider both flats in the 3rd group of semiquavers in bar 38 (e2 and a1) and a  in the 3rd group in bar 40 (c2) to be necessary. Some of them were added in GE1 (the  of a1) and in EE4 (), while GE2 and subsequent GE,s include all of them.

In A (→FE) there is no  before the 4th semiquaver, which is a patent oversight. The sign was added in GE and EE. All signs in the 2nd group of semiquavers are our addition, introduced due to different rules of their validity with an octave sign.

In A (→FE) there is no accidental before the 4th semiquaver. There is no reason to doubt that it is a typical of Chopin inaccuracy, resulting from the rules of validity of the accidentals, which in fact were not fully established in Chopin's notation. It is confirmed by the  written in this place in FED. In spite of this, in GE1 (→GE2) there is a  before this note, which is certainly a mistake.

In A (→FE1) there are no flats lowering d2(3) to d2(3). In FE2 only the second was added. GE and EE present the correct text.
