(b c1517; d Antwerp, 19 Nov 1595). Flemish composer, music editor, singer and teacher.
"He was an innovator among mid-16th-century Flemish composers, and his style bridges the period between that of Gombert and the mature Lassus. His works are characterized by careful attention to the relationship between text and music, reflecting the current humanistic outlook, and by chromatic harmony and inventiveness in the use of dissonances." (Grove's - Robin Leaver)
Since Waelrant is quite well-known, I refer to other and easily accessible sources with info about him. He published his own Psalm settings in 'Jardin Musical' (3 volumes 1555-1556). There also other Flemish contributions to this genre (Cauléry and: psalm 51 by Clemens non Papa, the one who is famous for his 3vv settings of the 'Souterliedekens' ). The publishing firm 'Waelrant -Laet' was also responsible for the three volumes of Jean Louys' Cinquante Pseaumes also in 1555. Below the title page of the 3rd volume of the Jardin Musical.
