Missa de Beata Virgine

The Missa de Beata Virgine is a musical setting of the Ordinary of the Mass, by Renaissance composer Josquin des Prez. Though formerly believed to have been a late composition on the basis of stylistic analysis (Osthoff asserts 1513), evidence from Burchard’s Diary proves that the mass was written sometime before September 23, 1497. It was the most popular of his masses in the 16th century.

The Missa de Beata Virgine is unusual among Josquin's masses in that the first two movements are for four voices, and the last three for five, with the fifth voice derived canonically. Like most musical settings of the mass Ordinary, it is in five sections, or movements:
Kyrie
Gloria
Credo
Sanctus
Agnus Dei
