duende /duːˈɛndeɪ/ (n.)– a quality of passion and inspiration
This Spanish term implies something magical or enchanting. It originally referred to a supernatural being or spirit similar to an imp or pixie (and is occasionally borrowed in that sense into English with reference to Spanish and Latin American folklore). Now, it has adapted to refer to the spirit of art or the power that a song or piece of art has to deeply move a person.
