Henze described the score as a "recital for four musicians". They consist of a baritone who portrays El Cimarrón himself, a guitarist, a flautist and a percussionist, although all four musicians play percussion instruments during the work. The flautist also plays the Japanese "ryūteki" and the Italian "scacciapensieri" (Jew's harp), as well as the four conventional orchestral flutes.
