goal. Morales was the first Spanish composer of international renown. His works were widely distributed in Europe, and many copies made the journey to the New World. Many music writers and theorists in the hundred years after his death considered his music to be among the most perfect of the time. Masses Morales's masses, of which 22 survive, use a variety of techniques, including cantus firmus and parody. Six masses are based on Gregorian chant, and these are mostly written in a conservative cantus-firmus style. Eight of his masses use the parody technique, including one for six voices based on the famous chanson Mille regretz, attributed to Josquin des Prez. The melody is arranged so that it is clearly audible in every movement, usually in the highest voice, giving the work considerable stylistic and motivic unity. Morales also wrote two masses on the famous L'homme armé tune, which was so often set by composers in the late 15th century and 16th century; one of these is for four voices, and the other for five. The four voice mass uses the tune as a strict cantus firmus, and the setting for five voices treats it more freely, migrating it from one voice to another. In addition, he wrote a Missa pro defunctis (a Requiem mass). Its peculiarities of transmission, as well as its apparent incomplete editing, suggest that it may be his last work.
