In 1933, Lorca gave a lecture in Buenos Aires. He described duende as a "black sound." Here are his words, some of which I have already given.
"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."
"Spain is moved by the duende, for it is a country of ancient music and dance where the duende squeezes the lemons of dawn - a country of death. A country open to death.
Everywhere else, death is an end. Death comes, and they draw the curtains. Not in Spain. In Spain they open them. Many Spaniards live indoors until the day they die and are taken out into the sunlight. A dead man in Spain is more alive as a dead man .... [H]is profile wounds like the edge of a barber's razor."
