In the 16th century, more and more composers set the Requiem Mass. In contrast to practice in setting the Mass Ordinary, many of these settings used a cantus-firmus technique, something which had become quite archaic by mid-century. In addition, these settings used less textural contrast than the early settings by Ockeghem and Brumel, although the vocal scoring was often richer, for example in the six-voice Requiem by Jean Richafort which he wrote for the death of Josquin des Prez. Other composers before 1550 include Pedro de Escobar, Antoine de Févin, Cristóbal Morales, and Pierre de La Rue; that by La Rue is probably the second oldest, after Ockeghem's.
