This is a song book. When the learned first gave serious attention to popular ballads, from the time of Percy to that of Scott, they laboured under certain disabilities. The Comparative Method was scarcely understood, and was little practised. Editors were content to study the ballads of their own countryside, or, at most, of Great Britain. Teutonic and Northern parallels to our ballads were then adduced, as by Scott and Jamieson. It was later that the ballads of Europe, from the Faroes to Modern Greece, were compared with our own, with European Marchen, or children’s tales, and with the popular songs, dances, and traditions of classical and savage peoples. The results of this more recent comparison may be briefly stated. Poetry begins, as Aristotle says, in improvisation. Every man is his own poet, in moments of stronge motion, expresses himself in song.
