composition: Op. 10 No 9, Etude in F minor

No title nor dedication in AI

in A (contextual interpretation)

in FE1

in FE2

in GE

in EE3

in EE4

..

In the main text we give the title and dedication in the undoubtedly authentic version adopted in FE. The extensions of both the title (in GE and EE) and dedication (in EE) most probably come from the editors. See Etude in C, No. 1, bar 1.

b. 1-7

composition: Op. 10 No 9, Etude in F minor

Slurs for 5 & half bars in AI

2 bars in A

1 bar in FE (→GE,EE3)

7 bars in EE4

..

The sources differ in the length of the initial phrase of the Etude, provided with the slurs in the L.H. As there is no doubt that the aforementioned slurs are written as a model and the similar slurring generally applies in the entire Etude, all these notations should be considered as equal. In the main text we give the version of A, as undoubtedly authentic and later than AI (in FE the missing slurs in bar 2 may be accidental). See also bars 8 and 9-16.
