In 1999, American music composer and researcher Pozzi Escot (pictured below) published The Poetics of Simple Mathematics in Music, a study of the geometrical grounding and mathematical structure of various music traditions from the Middle Ages, Romantic era, Native American Indians or contemporary European avantgarde. Among the examples included in her book was a geometrical drawing (see below) after the Kwakiutl Indians’ Raven Song, featured in a Folkways LP published 1981 (sound excerpt).
Born in Lima, Peru, in 1933, Pozzi Escot teaches music theory and composition at New England Conservatory. She is the editor of Sonus - Journal of Investigations into Global Musical Possibilities. In 1976, with Robert Cogan, she wrote Sonic Design: The Nature of Sound and Music.
