Anchieta's Missa Sine nomine, also called the Missa quarti toni, is here presented together with motets and pieces relevant to the liturgy, with the intention of evoking the sound of a liturgical ceremony of the period of the composer. All the pieces are dedicated to the Blessed Virgin, In honorem Beatae Mariae Virginis. The well-known melody of L'homme armé is used by Anchieta in the third voice of the Agnus Dei, and partly in the Kyrie, Sanctus and Benedictus of the Mass, while the principal theme of the Gloria is from Mass XV of the Graduale Romanum. His Salve Regina alternates Gregorian chant and polyphony in ten sections.
