Heitor Villa-Lobos's Étude No. 9, part of his Twelve Études for Guitar, was first published by Max Eschig, Paris, in 1953.
The piece is in F-sharp minor and is marked Très peu animé, and evokes the nostalgic countryside atmosphere associated with the cavaquinho.
Étude No. 9 is a study in arpeggios and slurred notes, developing musical ideas by Carcassi and Carulli. There is an emphasis on thirds, as in the Fifth Étude.
