b. 37-50

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

..

In bars 37-50 in AI there are no performance indications, as a result of which we do not consider this version as an alternative to the remaining sources and we do not discuss it in detailed notes. Similarly in subsequent bars until the end of the Etude.

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

No ornaments in AI & A

Mordants in FE (→GE,EE)

..

The mordents were added by Chopin in a proofreading of FE (→GE,EE). It is a part of a wider proofreading of the mordents' use in the theme of the Etude.
