Claude Le Jeune was a Franco-Flemish composer born around 1528 in the Hainaut region who established his career in Paris from the mid-16th century within the late Renaissance, writing chansons, airs and psalm settings. Associated with the practice of musique mesurée and close text-setting, he helped develop measured song and refined polyphonic techniques that linked secular chanson traditions with psalmody and other sacred repertories within the French cultural milieu.
