"When a rural Ecuadorian, in the heart of the mountains, listens on his transistor radio to the Chilean Victor Jara singing his “Plegaria a un Labrador” (A farmers prayer) he is, although he may not realize it, listening to a piece of folklore. Such songs belong to a group of sometimes ephemeral phenomena which might be called “subjective folklore”, and which have not yet been given a place among the categories made by folklore specialists."
