The Corpus mensurabilis musicae (CMM) is a collected print edition of most of the sacred and secular vocal music of the late medieval and Renaissance period in western music history, with an emphasis on the central Franco-Flemish and Italian repertories. CMM is a publication of the American Institute of Musicology, and consists of 109 series (individual volumes or sets of volumes) as of 2007. Renowned composers whose works have appeared in other collected editions, such as Josquin des Prez, Giovanni Pierluigi da Palestrina, and Orlande de Lassus, are generally excluded from the set.
