Folk music in general, especially flamenco, tends to embody an authenticity that comes from a people whose culture is enriched by diaspora and hardship; vox populi, the human condition of joys and sorrows.
The duende is seen, in Lorca's lecture, as an alternative to style, to mere virtuosity, to God-given grace and charm (what Spaniards call "ángel"), and to the classical, artistic norms dictated by the Muse.
To a higher degree than the muse or the angel, the duende seizes not only the performer but also the audience, creating conditions where art can be understood spontaneously with little, if any, conscious effort.
It is, in Lorca's words, "a sort of corkscrew that can get art into the sensibility of an audience... the very dearest thing that life can offer the intellectual."
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."
It 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."
[6] Although perhaps not ideal illustrations of the spirit of the term, the following are examples applied to other contemporary, non-flamenco contexts: In March 2005 Jan Zwicky (University of Victoria) used the notion of duende in the context of contemporary music at a symposium organised by Continuum Contemporary Music & the Institute for Contemporary Culture at the Royal Ontario Museum, an event televised by Big Ideas: [The second way music can be new is] when it possesses duende: "black sounds", as Lorca called them, the dark counterpoise to Apollo's light, music in which we hear death sing.... Duende lives in blue notes, in the break in a singer's voice, in the scrape of resined horsehair hitting sheep gut.
Even if it is structurally amorphous or naïvely traditional, music whose newness lies in its duende will arrest our attention because of its insistence on honouring the death required to make the song: we sense the gleam of the knife, we smell the blood...

Australian music artist Nick Cave discussed his interpretation of duende in his lecture pertaining to the nature of the love song (Vienna, 1999): In his brilliant lecture entitled "The Theory and Function of Duende" Federico García Lorca attempts to shed some light on the eerie and inexplicable sadness that lives in the heart of certain works of art.
The writer who refuses to explore the darker regions of the heart will never be able to write convincingly about the wonder, the magic and the joy of love for just as goodness cannot be trusted unless it has breathed the same air as evil — the enduring metaphor of Christ crucified between two criminals comes to mind here — so within the fabric of the love song, within its melody, its lyric, one must sense an acknowledgement of its capacity for suffering.
