"Those dark sounds are the mystery, the roots that cling to the mire that we all know, that we all ignore, but from which comes the very substance of art. 'Dark sounds' said the man of the Spanish people, agreeing with Goethe, who in speaking of Paganini hit on a definition of the duende: 'A mysterious force that everyone feels and no philosopher has explained.'
So, then, the duende is a force not a labour, a struggle not a thought. I heard an old maestro of the guitar say: 'The duende is not in the throat: the duende surges up, inside, from the soles of the feet.' Meaning, it's not a question of skill, but of a style that's truly alive; meaning, it's in the veins; meaning, it's of the most ancient culture of immediate creation.
This 'mysterious force that everyone feels and no philosopher has explained' is, in sum, the spirit of the earth, the same duende that scorched Nietzche's heart as he searched for its outer form on the Rialto Bridge and in Bizet's music, without finding it, and without seeing that the duende he pursued had leapt from the Greek mysteries to the dancers of Cadiz and the headless Dionysiac scream of Silverio's siguiriya."
