Johannes Nucius

Johannes Nucius (also Nux, Nucis) (c. 1556 – March 25, 1620) was a German composer and music theorist of the late Renaissance and early Baroque eras. Although isolated from most of the major centers of musical activity, he was a polished composer in the style of Lassus and penned an extremely influential treatise on the rhetorical application of compositional devices.
