Clear as mud, right? What the heck is duende or the Duende?
According to Wikipedia, “Lorca writes: ‘The duende, then, is a power, not a work. It is a struggle, not a thought… everything that has black sounds in it, has duende. [i.e. emotional “darkness”] [...] This “mysterious power which everyone senses and no philosopher explains” is, in sum, the spirit of the earth, the same duende that scorched the heart of Nietzsche, who searched in vain for its external forms on the Rialto Bridge and in the music of Bizet, without knowing that the duende he was pursuing had leaped straight from the Greek mysteries to the dancers of Cadiz or the beheaded, Dionysian scream of Silverio's siguiriya.’ [...] ‘The duende's arrival… brings to old planes unknown feelings of freshness, with the quality of something newly created, like a miracle, and it produces an almost religious enthusiasm.’” (Teoría y juego del duende" ("Theory and Play of the Duende"); Maurer (1998) pp. 48-62)
