Writers of the time explored its links with grammar and rhetoric, reported on the music of non-European peoples, and debated the role of music in religious and other spheres. The forty-five readings chosen for this volume by Gary Tomlinson cover a gamut that includes composers, theorists, poets, philosophers, courtiers, scholars, kings, and popes. Through the eyes of Bembo and Byrd, Du fay and Erasmus, Peacham and Palestrina, Charles IX and Gregory XIII, Calvin and Castiglione, Aaron, Tinctoris, Morley, and Zarlino, we see the many worlds of music in the Renaissance.
