Lihué dulce lihué, a new score for unnacompained clarinet has already been published by Cayambis Music Press – Latin American Classical Sheet Edition! In the Mapuche language, spoken by the indigenous inhabitants south-central Chile and southwestern Argentina, “lihué” (catch light in English) refers to an errant song that alludes to an imaginary and timeless South American past. The name, along with the word “dulce” (sweet), forms a pun that gives name to an enigmatic figure, who is barely visible in the shadowy dusk.
