b. 27-28

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

Semiquavers in CLI & FE (→GE,EE

Crotchets in Ap

..

The crotchets in the lower voice in the R.H., in Ap on the last beats of these bars, are in strong articulation contrast with the remaining semiquaver two-note chords, which is additionally underlined with the accents. In the main text we give the homogenous, as far as the sound is concerned, version of FE (→GE,EE).

b. 32-35

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

Semiquavers in CLIFE (→GE,EE

Crotchets & semiquavers in Ap

..

Same as in other places, we consider the version of Ap with the extended articulation of the accompanying two-note chords as a transitional stage in the process of shaping of the Etude's text or even an exclusive one-time idea.
