Thibault has the largest surviving corpus of literature from the northern trouveres of France, and, perhaps, of any trouvere whatsoever. He composed in almost every form known at the time including courtly and pastoral verse, crusade songs, jeux-partis, and religious works. Some of the religious works include a lai, serventois and songs in the form of chansons to the Virgin. As diverse as his choice of settings was, so to did he vary his rhythms. Employing many strophic structures, including a number of almost characteristic decasyllabic settings, Thibault also varied his modal structures but rarely exceeded the compass of a seventh, eighth or ninth. Modal structures were usually built around the "final" but initial notes were rarely far from the modal center with equally rare beginnings on the modal center itself. ~ Keith Johnson, Rovi
