"Understanding, and eventually defining tayil [a "musical" genre] demands a delineation of its relationships to other phenomena in the Mapuche world. As a basis for departure we may say that tayil is the lifeforce that an individual shares with all living or deceased members of his/her patrilineage. The shared soul of a patrilineage is termed kimpen; the essence of a kimpen can be verbalized or activated only through the performance of its respective tayil."
