Duende.

The duende, then, is a power, not a work. It is a struggle, not a thought. I have heard an old maestro of the guitar say, 'The duende is not in the throat; the duende climbs up inside you, from the soles of the feet.' Meaning this: it is not a question of ability, but of true, living style, of blood, of the most ancient culture, of spontaneous creation.

Everything that has black sounds in it, has duende.

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.
