Loys Bourgeois (c. 1510 to 1559) French composer and theorist. He was the first editor of the Calvinist Psalter, which set the new French translations of Marot and Bèze. He subsequently published four-voice harmonizations of these melodies in various styles. He also wrote a musical primer, Le Droict chemin de musique (1550) aimed at young musicians. His four chansons, written in the secular idiom of the day, were issued by Moderne and Du Chemin. “Ce moys de may” (not in Du Chemin) is a setting of a complete rondeau cinquain.
