b. 9-15

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

Semiquavers in CLI & FE (→GE,EE) 

Crotchets in Ap
..

The articulation of the accompanying two-note chords, extended in Ap in bars 9-10 and 13-15, seems to be a one-time exclusive idea or a certain transitional phase in the shaping process of the Etude's text.

b. 9

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

No accidental in CLI & Ap

 before a1 in FE (→GE,EE) 
..

Chopin added a cautionary  before a1 still in the handwritten base text for FE (→GE,EE). In the situation in which the opening phrase of the Etude appears already for the third time, written from a new line of the text, the sign seems to be superfluous.

b. 9-13

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

..

The naturals returning a1, d2 and f2 in bars 9 and 13 are inaccurately written in some of the sources. In CLI they are totally absent, although in bar 13 the sign returning d2 is before the last semiquaver in the lower voice. In FEcor Chopin added them only in bar 9, yet, eventually, he also added the  returning f2 in bar 13 in FE (→EE2). In GE1 only the sign returning d2 in bar 13 is missing. The remaining sources have the correct notation.

b. 9

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

..

FE (→GE,EE) has cautionary naturals before the last semiquaver in bars 9 and 13. Despite being undeniably authentic, the signs are, according to us, unnecessary in such a regular figuration.

b. 9-17

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

No marks in CLI & Ap

Dots in FE (→GE,EE)
