Missa L'Homme armé is a part of an mass by Giovanni Pierluigi da Palestrina.
Composers of the late Renaissance began to work with freer and longer melodic lines.
Imitation begins and is used between voices, and each singer's melody fluctuates less in pitch and becomes more tied to the text.
In the Sanctus, the tenor sings the L'homme armé melody beginning on F; on the jubilant text Hosanna, the note values are diminished such that the structural function is hidden.
Agnus Dei II begins as if the cantus firmus is present on 'A', but proceeds to a freely composed trio.
Agnus Dei III places the now-familiar tune in extremely long notes sung by the highest voice.
