Copied from the Great METZLER Music Dictionary 4.0:
de CLEVE, Johannes de, *around 1529 duchy or city of Cleve, † 7/14/1582 in Augsburg; Flemish composer. He presumably spent his youth in the Netherlands as his compositions can be found in the choir books of St. Peter's Church in Leyden and in the anthologies of T. Susato. From 1554-64 he was a singer (tenorist) at the court chapel of Emperor Ferdinand I., then (from 1567 at the latest) until 1570 director of the choir at the court of Archduke Charles II in Graz. In 1578, after a period in Vienna without a position it has been confirmed that he was then in Augsburg where the local cathedral music director Bernhard Klingenstein was one of his pupils. CLEVE who belonged to the tradition of the Dutch vocal polyphony, mainly wrote church music as well as several so-called state motets.
