Early Music History is devoted to the study of music from the early Middle Ages to the end of the seventeenth century. It demands the highest standards of scholarship from its contributors, all of whom are leading academics in their fields. It gives preference to studies pursuing interdisciplinary approaches and to those developing novel methodological ideas. The scope is exceptionally broad and includes manuscript studies, textual criticism, iconography, studies of the relationship between words and music and the relationship between music and society. Articles in volume twelve include: Guerrero L'homme arme masses and their models; Oral and written transmission in Ethiopian Christian chant; The motets of Philippe de Vitry and the fourteenth-century renaissance; Sight, sound and ceremony in the chapel of Galeazzo Maria Sforza.
