Unfortunately, Heitor Villa-Lobos didn't write for the organ.
This is my own arrangement of his famous aria, from Bachiana Brasiliera n°5, suite for soprano and cellos (or guitars) composed in 1938, a mixing between Brazilian folk tunes and baroque language, inspired by J.S. Bach.
The aria is a vocalise, accompanied by strings pizzicato. The central part contains words, from a short poem, with a lot of repeated notes (I replaced them by long notes) , accompanied by bowed cellos.
