b. 20

composition: Op. 10 No 6, Etude in E♭ minor

..

In A (→FEGE1GE2,→EE2EE3) there is no  raising G to G. This patent accuracy was corrected in FES and later editions.

In the sources the natural raising g to g is before the first sustained semiquaver in the bar. We move it before the 4th note, according to General Editorial Principlesp. 3.

composition: Op. 10 No 6, Etude in E♭ minor

No dot in FE (→GE1)

Dotted crotchet in A, EE & GE2 (→GE3GE4GE5)

..

Lack of the dot prolonging in FE (→GE1) is probably an error. The sign was added in EE, as well as in GE2 and subsequent GE,s.

The change of the notation introduced by Chopin in a proofreading of FE (→GE,EE) manifests both the harmonic progression and rhythmic values (shorter sound of g1). In EE2 (→EE3) the quaver flag is missing.
