Here is the Spanish poet and playwright Federico Garcia Lorca’s mesmerizing 1933 lecture/essay The Theory and Play of the Duende, as translated by A.S. Kline.
Some excerpts:
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.
