Book excerpt: Both from the Ears and Mind offers a bold new understanding of the intellectual and cultural position of music in Tudor and Stuart England. Linda Phyllis Austern brings to life the kinds of educated writings and debates that surrounded musical performance, and the remarkable ways in which English people understood music to inform other endeavors, from astrology and self-care to divinity and poetics. Music was considered both art and science, and discussions of music and musical terminology provided points of contact between otherwise discrete fields of human learning. This book demonstrates how knowledge of music permitted individuals to both reveal and conceal membership in specific social, intellectual, and ideological communities. Attending to materials that go beyond music’s conventional limits, these chapters probe the role of music in commonplace books, health-maintenance and marriage manuals, rhetorical and theological treatises, and mathematical dictionaries. Ultimately, Austern illustrates how music was an indispensable frame of reference that became central to the fabric of life during a time of tremendous intellectual, social, and technological change.
